Article Body:
In the last few years the most dangerous computer viruses are disappearing. Macro viruses and script viruses are almost extinct.

But in the meantime there was an increase of trojan, backdoor, rootkit and spyware which can be used to remotely control a pc. There was an increment of malware that includes spyware programs from 54.2% to 66.4%.

Rootkits are becoming famous. They are used by virus writers to remotely control infected computers and use them for stealing money and perform DDOS attacks.

In the Windows world the rootkit term is usually used to describe viruses and malware programs that use a special technique to hide into the system environment. In Unix environment, rootkits are usually rewritten tools of the operating system that are used to hide data from the users. For example the ls command can be rewritten so that it doesn?t show certain files.

There exist user-mode rootkits and kernel-mode rootkits. User-mode rootkits are basically normal processes that can be easily detected and eliminated. Kernel-mode rootkits are hidden inside of the operating system itself and caan be very hard to detect and eliminate.

SubVirt is the name of a research project directed by Microsoft with the help of the University of Michigan. Currently malware software and detection software have both control of the system at kernel-mode level. Virus writers are trying to find the best way to hide their malware in front of detection software and maintain at the same time the have maximum control over the machine.

The result of this research is the VMBR, Virtual Machine Based Rootkit. A Virtual Machine is a special software layer that works between the hardware and the operating system. On a Virtual Machine also the operating system runs in user mode. The rootkit would install itself between the operating system and the hardware and would have a total control of the system.

In order to work, the VMBR needs to start up before the operating system, so it?s necessary to modify the Master Boot Record in order to make it work. At computer startup the Virtual Machine would start and then it would run the operating system in a virtual environment. Potentially it can run two operating systems at the same time, the user?s Windows and a specially crafted malware operating system that would be invisible to the Windows system and to the user.

The problem with this type of malware software is that it would slow down the system. During their tests Microsoft noticed that the system sturtup takes about 30 seconds more with the Virtual Machine and it eats about 3% of system resources.

It?s also important to point out that the virtual machines that Microsoft used had the size of about 100 megabytes, which is too much to fit in a common MBR.

Rootkits ? Hidden Hazards on Your System

Summary:
With the rootkit in place, the hacker has a virtual backdoor into your system. He can read your keystrokes, record passwords, gather information from your network and change your data and files.

Keywords:
rootkits, root kits, spyware, malware, viruses

Article Body:
If you?re concerned about security on your computer network, there?s a new word to add to your vocabulary ? rootkit. A rootkit is a set of utilities installed on your computer whose purpose is to hide what other programs are doing. They?ve been around for a few years, but they didn’t really hit the security spotlight until November 2005. That was when researchers discovered that some CDs from Sony were installing a rootkit on user computers as part of their DRM (Digital Rights Management) software. The purpose of the rootkit was to prevent the DRM software from being detected and uninstalled ? but there was an unintended side effect. The rootkit opened a security hole on those computers that couldn?t be detected by standard security software, and left them vulnerable to attacks by malicious software and hackers.

That?s bad news for users and IT professionals who depend on virus and spyware detection programs to alert them to an invader on their networks. Generally, when you?re computer is infected by spyware or malware , it can be detected by monitoring your computer activity. You can check the running processes and find programs that shouldn?t be loaded. You can run a virus or spyware scanner to find registry keys and files that fit certain patterns. You can monitor activity coming in over a network.

A rootkit makes all of those defenses worthless by hiding the keys, files, processes and communications from your computer operating system. What your computer can?t see, it can?t report and you can?t fix. The methods used to hide the files and processes vary and are getting more and more sophisticated. Most do it by ?hooking? into a process that Windows expects to find running, either by replacing the process files, or by adding itself into them.

With the rootkit in place, the hacker has a virtual backdoor into your system. He can read your keystrokes, record passwords, gather information from your network and change your data and files. A hacker with access to your system through a rootkit can reinstall hacking programs, access your accounts and your users? accounts and wreak general havoc. It?s the ultimate Trojan backdoor.

Once a rootkit is installed, it?s virtually impossible to detect and remove. When a virus detection or spyware program runs, they don?t see the rootkit processes ? they see the process that?s cloaking it. Some may alter their own files with the details and stats associated with the files that they?re replacing so that operating systems don?t notice a difference. A sysadmin who is an expert in network security may be able to detect it by running system checks from an uninfected machine, but most agree that once a rootkit has been installed, the only way to be sure you?ve removed it is to wipe the drive clean and install the operating system.

Because rootkits don?t install themselves, you can block them by blocking attempts to penetrate your network. One way to effectuate this is to install a spyware or malware protection program to help prevent rootkits from being installed at the server level or on individual desktops. The key is to practice excellent network security at all times so that you block the programs that install rootkits.

Notebook computers bring a tremendous convenience to personal computing. Just sit within range of a wireless hotspot and you can connect to your office or home network, access your email, and complete important projects for work. However, roaming from one unsecured wireless network to another can leave your computer vulnerable to malicious software attacks.

Spyware and Viruses

If you are connected to a wireless network without its own firewall, hackers can easily intercept the signals you send and receive across the airwaves. Malicious individuals can also install spyware and viruses on your computer.

Spyware refers to an application designed to track a computer user’s internet activities, keep note of sites visited, and gather other information. The term, “spyware,” can also refer to any non-viral malicious software, including software that takes over your internet connection, pops up unwanted advertisements, or even blocks your internet connection. A tracking program is technically labeled as spyware only if the computer user does not consent to the download or installation.

Spyware collects information and sends it back to the spyware controller. The owner of the spyware program usually sells gathered information to marketers. For instance, spyware can get a computer user’s email information, using that information to bombard the user with advertisements and spam. Spyware is also known as “malware” (Malicious Software), as it can be used to aid identity theft and fraudulent activities (some spyware programs mine credit card information and other sensitive financial information). Keylogging programs, used to steal credit card information and passwords by monitoring everything a user types, fall under the umbrella of spyware/malware.

Viruses are another type of malicious software. A virus is a piece of code that attaches itself to a program, a file, or your boot sector. These malicious programs are called viruses because they work much like a viral infection ? they spread to other files, programs, and even computers, and they are designed explicitly to damage your files and destroy your applications.

Protecting Your Notebook from Spyware and Viruses

Protecting your notebook computer from spyware and viruses protects you against fraud and protects your privacy, too.

The first thing that you need to do is install a secure web browser. Internet Explorer is particularly vulnerable to unauthorized scripts which could be run and installed on your computer without your knowledge. Instead of using Internet Explorer, you can try using Mozilla Firefox, one of the most secure web browsers around. Firefox will always inform you about any download or installation, inform you about suspect sites, and update your browser automatically to continually improve security.

Aside from using Firefox, it is important that any computer user install a personal firewall to block unauthorized access attempts. For Windows XP users, Comodo Personal Firewall is a free option (there is an Alpha version of Comodo Personal Firewall Version 3, which adds Vista support, but this would not be a stable option until they reach the final release). Even the best firewall can sometimes allow spyware through, however, so scan your computer with a free program like Spybot: Search

It?s not always easy to spot a scam. Many times, checking with the BBB and other resources simply is not sufficient because the scam is too new. But when you are looking for a work at home opportunity of any kind, it helps to know what red flags to be aware of, whether in a job or business opportunity.

The first rule of thumb is can you follow the money? That is, can you figure out how the company will be earning money from your efforts? If you?re offering lifetime free services to someone and earning a large commission every time someone signs up, where does the money come from? It?s easy to tell yourself it can?t be a scam because no money is being spent, but you need to consider more possibilities. What information are you giving them? What about your customers? Can that be used against you? Do you have to download anything at any point? Spyware and/or affiliate commission theft could be the goal.

Second, is the pay commensurate with the effort you are putting forth? If they are offering 2-3 times the going rate for a job, but you have to pay for training, it?s probably a scam. They?re relying on your need to earn money and desire to earn lots of it with little effort to cloud your judgement. Similarly, if you are earning commissions for your efforts, does it look like the company you will be representing can possibly be making a profit? This is very similar to point #1 above, but worth considering on its own.

Next, what kinds of promises are being made to you and to the customer? Are they even remotely possible? This can be either a bad case of exaggeration, which may concern the FTC, or a sign of a scam. In either case you do not want to be involved.

In the case of home business, I am always wary of pre-launch hype from marketers I have never heard of. If they don?t have a name in the business, how do I know their product will be any good? It could just be a way to get information, get you to download something, etc., rather than the introduction of a real, quality product. Pre-launch marketing does get used by reputable marketers too, but not very often. After all, if you?re offering a quality product do you really need to get people excited about it before they can see it. It might be fun, but not all that necessary. Pre-launch hype also has a way of annoying potential customers, as they wade through months of excessive advertising and spam about the product. It generally makes much more sense for a company to launch a product when ready, rather than give a buyer time to change his or her mind because they?re tired of the hype.

There is no guarantee, however, that a given opportunity is a scam just because it looks like one. It is possible to misjudge, but you have to decide if you would rather miss an opportunity that could hurt you financially or destroy your reputation if it is a scam than take a chance on it. If too many warning flags go up, it is probably not worth it in my opinion, but you have to decide for yourself.

Summary:
This article discusses free music downloads and the hazards of downloading the wrong materials. It talks about the shifts that are now occurring in the music industry and the fact that there is now a substantial amount of free music on the web that is available for free as a legal music download.

Keywords:
music

Article Body:
While downloading music is one of the most popular online activities, besides social networking and playing games, there is a lot of information that is not made available to the public at large.

There are a number of serious issues that should be understood when downloading music (which most people overlook) and there are also ways to obtain free music that are simply unknown by the majority of people online.

This is very important when considering the growing trend by the large music companies, of suing individuals who infringe on their copyrights. Court records show a large number of out of court settlements, with fines ranging from $3000 to $5000, and maximum awards in excess of $250,000.

As if the fines and legal issues where not enough of a problem now there is the added danger of downloading music imbedded with spyware and viruses. The need to be cautious in your quest for free downloadable music is evident.

Having access to free music download files means that you can enjoy as much music as you want in your own home whenever you want it. You will find that many musicians are now freely giving away their music as a way to promote themselves and their bands. The concept of free legal downloads means that you have permission from the author or creator to download their intellectual property.

Free music downloads have surged in popularity since the emergence of the Internet and even more so in the last few years. With the advent of iTunes, the mass population has become more accustomed to buying their music from the Internet in the form of single track downloads from membership websites. No longer is it necessary to purchase an entire album when you really only want a single track.

A huge shift occurred and people have moved toward digital media for the ease of use and speed of acquisition that it offers. As such, more and more people have begun to search the Internet for music rather than going to the local record shop.

You can find and use free and legal music downloads from a number of sources and in a number of ways. The key is to be aware of the dangers and also to know what you can use legally and what will get you into trouble.

They may think they are the Yosemite Sam?s of the modern world, but you are the New Sheriff in town! Marauders of today do not come moseying up bow-legged into your path with a six-gun slung across their hip telling you to, “Stick ?em up, or else.” Instead, today?s modern outlaws can be in and out of your life without a trace of you knowing what has happened. With the explosive popularity of the Internet, untold numbers of citizens are blindly allowing computer data miners to collect sensitive information from their computers. This ?mined? information can be used for many purposes, but the main issue here is that the information is stolen from people who quite literally hand it over with a smile. A random click here on a harmless looking popup or web link can mean the difference between a safe surfing experience, and one that results in a ?Stagecoach Robbery?.

Average Internet surfers just starting out have no idea if it?s normal for them to win a thousand dollars with a single click or not, much less if it?s normal for them to have to scroll through many sites to get to the one they first clicked on. Therein lays the Holy Grail for the modern day marauders.

Hijacking is one of the most serious threats to internet safety. These rascally scoundrels will set programs and lay in wait, watching your every move of your computer. They see that you innocently want to search for something and suddenly, you are taken to one of their websites. They hijacked your computer and made you go where they wanted you to go! Once at their site which are often fake search engines and portal sites, you begin to get pop-ups, they tag your computer with modern-day invisible post-it note reminders. Once these ?reminder? files are embedded, they function like little thieving robots, storing and sending information on all the searches, websites, links that YOU and your family have clicked on in the past three months. In addition to that, there have now been hidden programs installed on your computer that generate a myriad of pop-up ads. The crook has planted his hijack, and only has to sit back and watch his booty collect.

You and your entire family are exposed and at risk. Your banking info, your credit card statements, even your cell phone are all potential threats just because you just simply didn?t know you were making yourself an attractive target. Hijacking is one of the most alarmingly popular means of marauding of today, but take heart, there are ways to combat this problem and impose your own form of Martial Law to protect your family.

The first line of defense is a good firewall. Firewalls come in many different versions and are made by many companies. There are software firewalls, and hardware based ones as well, but they all serve a similar purpose. The purpose of a firewall is like a gate: nothing comes in or goes out through your Internet connection without you knowing about it. Firewalls, however, are only as good as the persons using them. Knowledge is power, and you should familiarize yourself with the normal functions and files that it takes to run them. When you know the real deal, counterfeit files or intruders are many times more likely to be recognized and apprehended. When this happens, you will not be finding yourself in uncharted territory and will be able to click “Access Denied” with confidence.
Secondly, the market has come out with some really good anti-hijacking software that are specially designed to prevent your browser from being overtaken and can eventually save you from a totally dominated and bombarded computer. Software such as this is not used as a replacement for a firewall or antiviral defense. In fact, today, a myriad of software solutions should be used to keep your system totally clean and under your control.

Lastly, a good anti-spyware program is a good means at combating the problem of hijacking. It will guard against the editing of your registry which would command the start up of malware as well as prevent any information from being broadcast over the net or emailed back to the user. Some anti-spy programs will also guard against hijacking, but if you are a victim of hijacking, they will also prevent the usual serious repercussions of the hijack. Remember, prevention is key. It is much easier to start with a clean system, implement a firewall, antiviral software, anti-spyware, and anti-hijack software than it is to painstakingly scrub clean an infected system. After all, it?s a lot easier to return to a mouth that has fed you, than to find another hand.

The last thing you should remember is that ownership is of utmost importance. If one chooses to be likened unto an ostrich and chooses to not educate themselves on the dangers that lurk about in this modern Wild West, that puts them at a severe disadvantage. Nobody is too old or too young to be aware of the dangers of this world, and it is just vital to change with the times and adapt. Familiarize yourself with firewalls and anti-hijacking software, get to know how your computer works, and you will be well on your way towards making sure you are safe from marauders!

There may well be some rootin-tootin, tech-savvy individuals out there, but you are the one with the badge in this horse town.

In the new computer age, We don’t always log on from home where our PC’s are thoroughly protected. (You took care of that already, right?) Cyber cafes, libraries, airports, hotels and other places offer use of a public terminal for those on the go. But, unfortunately, those computers may not always get secured well nor checked regularly. And, since others use them, they can get infected only minutes before it’s your turn.

Here are a few tips for how to protect your information while using a public computer.

Most of the email clients nowadays allow you to forward email from one account to another, just as you forward your phone calls. Take advantage of this feature to enhance your security.

If you plan to be away from home for a few days – but aren’t using your regular computer or laptop – try to forward your email to an account you set up especially for the trip. This helps protect your information a lot.

Both the account and the password are much less likely to be known to scam artists. Yet, you can retrieve any email sent while you’re away from your regular PC. Also, if the userid and password do get cracked, your ongoing risk is low, since you’ll be abandoning this temporary account shortly.

If you have to log in to a public computer with one of your regular username change the password the first time you use it away from home. Then change it back when you get back home, This limits your exposure time.

Public computers can contain a specific kind of spyware/trojan called ‘a key-logger’ that records your every keystroke. Apart from getting your logins and passwords, that also allows the thief to access anything else you typed in during your session. So, you must avoid making credit-card transactions online or accessing your online banking and credit-card accounts.

Before you go to any site that would require a username and/or password, disable any auto-complete or password storing feature. If you can because some public computers have these features locked down by the administrator.

Avoid unfamiliar sites, if practical, while you are away. Most online hacks come from auto-downloads of spyware, viruses, etc. Few of the sites you visit regularly are likely to have those. Just as you would avoid talking to unsavory strangers while on a trip, avoid dicey websites.

Defer clicking on ads while you’re away from home. Those can lead to just the kinds of sites mentioned above.

Once you are done using the public computer, erase – if you can – here again administrators may not allow you to access the feature – any Temporary Internet files, cookies, etc. This helps protect not only you, but leaves the computer in a better state for the next user.

Needless to say, don’t leave any downloaded files on the computer and never allow anyone to look over your shoulder while you are typing in a password or other sensitive information.

Paranoia isn’t needed. But a little awareness and sound judgment while using a public computer will help keep your information secure – then and after you get back home.

One last tip would be to use a better secure browser like Firefox or Opera while surfing on your home PC as well as a public computer.

Once you click on the various pop ups that it is incorporated in, the adware penetrates the various aspects of your computer system. You won?t even know in most cases that anything is going on until it is too late. It is important that you have an excellent software program for your computer that allows you to remove adware and continues to prevent it from attaching to your computer system in the future.

The main reason you need to worry about adware is it can compromise your personal information that is on the computer. Some of the adware just tracks the sites you look at so it can send you advertisements in that area of interest. Others are more aggressive and actually classified as spyware. These actually track everything you do and can give the sender access to your credit card account numbers and the passwords you use to access such accounts.

There are a few clues you can watch for that could indicate your computer has been compromised by adware. The most telling sign of adware is that you will start having more and more pop ups appearing on your computer. Pay attention to where you are taken when you type in a URL. If it is isn?t the site you indicated and you haven?t made any typos, it is a good possibility that adware is redirecting your browser.

In many instances the presence of adware will result in web pages opening slower and interrupted service of your internet access. If you see these signs it is vital you implement a way to fix it as quickly as possible. Do all you can to minimize the damage and to prevent it from happening again.

There are many different adware removal tools you can access online or purchase at retail stores. You need to make sure you are getting a quality program or it won?t be effective for stopping adware and spyware from affecting your computer. Some of these adware removal tools are free of charge and others you will need purchase.

It is worth it to invest in a quality adware removal program that will remove any problems you already have and prevent new ones from developing. Look for a quality program that offers continuous updates so you will never have to worry that your adware protection can be breached with advances such scrupulous people have made.

Ironically, some of the different free adware protection tools out there are actually nothing more than a clever way to provide you with adware. While you are installing it to protect your computer, you are actually giving such criminals access to everything they want.

It is never a good idea to click on any pop up advertisement no matter how appealing it is. They are likely infected with adware or even spyware that you need to avoid. Don?t fall for scams that ask you if you want them to scan your files or remove any viruses from your computer. These are designed to give them access to your information as soon as you click on them.

It is a good idea to have an operating system in place that will block out all pop ups on your computer. This is a good line of defense against the various types of adware and spyware. Since most people rely on their home computers for a variety of activities, you want to make sure your computer is safe and able to run as efficiently as possible.

One of the main ways to compromise internet security on your PC is via a program called a Trojan Horse. A Trojan Horse is a program that quietly runs in the background, inviting the user to run it, while spreading its malicious code. This code can do any number of things. It can start right away or it may simply install a program that won’t start for sometime. Once it does start, it can delete all of the files on the computer or it can infect the computer and try to infect other computers on the network. There are a number of ways spyware is delivered, and as a Trojan horse is the most common.

In addition to these things, spyware may infect your e-mail address book. Once this occurs, spam will be sent to every single person in every single infected address book.

The major difference between spyware like Gator and most other spyware programs is that users are understandably notified of its download before it actually occurs.

Another significant spyware threat is CoolWebSearch. This spyware can do a number of things to compromise your internet security. First, it can take over your current internet settings, making things display wrong, and causing other system inconsistencies.

The third major spyware threat is 180searchassistant. This program has both pop-up and pop-under ads based on the user’s search terms. Moreover, once a site is clicked on, a new browser window opens to display more advertisements based on the search terms. It constantly updates by itself, and it can display pop-up ads even when the internet is not running. In addition to compromising your internet security, it can cause system slow downs.

The fourth detrimental spyware threat to your internet security is ISTbar. This spyware program displays adult pop-ups, even when the internet is not in use. It can hijack your browser settings, reset your homepage, and cause continual cascading pop-ups while you are using the internet. It will continually download related files without your knowledge. Moreover, it can cause system slow downs.

The final major spyware threat to your internet security is Internet Optimizer. This program redirects your computer to its advertising sites. It also downloads and continually updates itself without your knowledge. The worst part about this spyware, though, is it leaves a back door open to your system so other viruses can penetrate your defenses.
