This is a rogue malware program

What this programs does:

Antivirus Vista 2010, Win 7 Antispyware 2010, and XP Internet Security 2010 are new rogues that are exactly the same program, but are shown with different names and interfaces depending on the version of Windows that it is run on. After I wrote this guide, I was told that this rogue goes under quite a few different names, which I have listed below:

• Antivirus Vista 2010
• Vista Antispyware 2010
• Vista Guardian
• Vista Antivirus Pro
• Vista Internet Security
• Vista Internet Security 2010
• XP Guardian
• XP Antivirus Pro
• XP AntiSpyware 2010
• XP Internet Security
• XP Internet Security 2010
• Antivirus XP 2010
• Antivirus Win 7 2010
• Win7 Guardian
• Win 7 Antivirus Pro
• Win 7 Antispyware 2010
• Win 7 Internet Security
• Win 7 Internet Security 2010

When installed, this rogue pretends to be an update for Windows installed via Automatic Updates. It will then install itself as a single executable called AV.exe that uses very aggressive techniques to make it so that you cannot remove it. First, it makes it so that if you launch any executable it instead launches Antivirus Vista 2010, Win 7 Antispyware 2010, or XP Internet Security 2010. If the original program that you wanted to launch is deemed safe by the rogue, it will then launch it as well. This allows the rogue to determine what executables it wants to allow you to run in order to protect itself. It will also modify certain keys so that when you launch FireFox or Internet Explorer it will launch the rogue instead and display a fake firewall warning. Last, but not least, when try to browse to a web site, it will hijack your browser and state that the site is a security risk and not allow you to visit it.

There are a total of 14 images you can view.

Once started, the rogue itself, like all other rogues, will scan your computer and state that there are numerous infections on it. If you attempt to use the program to remove any of these infections, though, it will state that you need to purchase the program first. In reality, though, the infections that the rogues states are on your computer are all legitimate files that if deleted could cause Windows to not operate correctly. Therefore, please do not trust anything it states are infections.

While running, Antivirus Vista 2010, Win 7 Antispyware 2010, and XP Internet Security 2010 will also display fake security alerts on the infected computer. The text of some of these alerts are:

Tracking software found!
Your PC activity is being monitored. Possible spyware infection. Your data security may be compromised. Sensitive data can be stolen. Prevent damage now by completing security scan.

XP Internet Security 2010 Firewall Alert!
XP Internet Security 2010 has blocked a program from accessing the Internet
Internet Explorer is infected with Trojan-BNK.Win32-Keylogger.gen
Private data can be stolen by third parties, including credit card details and passwords.

Just like the scan results, these fake security warnings and alerts are all fake and should be ignored.

Without a doubt, this rogue is designed to scam you out of your money by hijacking your computer and trying to trick you into thinking you are infected. Therefore, please do not purchase this program , and if you have, please contact your credit card company and dispute the charges.

2. From another computer, please download Malwarebytes' Anti-Malware, or MBAM, and the reg files from the following locations and save it to an external media such as an external hard drive or a USB flash drive. We will then use the external drive or flash drive to to transfer these files to your infected computer. If you do not own a USB flash drive, you can get one from any local or online computer store for a small price. An example of a good and cheap one can be found at Newegg.

If it is not, you can launch it by running any program on your computer as that will trigger the rogue program to run. Once running, do not close it during the entire length of this guide.

When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.
    
     
13. When MBAM has finished removing the malware, it will open the scan log and display it in Notepad. Review the log as desired, and then close the Notepad window.
