Windows Antivirus Booster

What is Antivirus Booster?

Windows Antivirus Booster is a fake antivirus program, which infiltrates operating systems using fake online security warning messages. After successful installation, this rogue software blocks the desktop, performs fake security scans, and reports the 'detection' of various Trojans and high-risk malware infections.

PC users should be aware that none of the security threats indicated by Windows Antivirus Booster exist on their computers. This program is created by cyber criminals who make money from users who fall for the trickery displayed by this bogus program and go on to purchase the 'full version'.

Note that paying for 'ultimate protection' (the 'full version') of Windows Antivirus Booster is equivalent to sending your money and credit card information to cyber criminals - you will lose your money and your credit card information could be used for further thefts.

Windows Antivirus Booster also modifies the registry entries of an infected operating system by blocking execution of installed programs and disabling the Task Manager. This program is a scam. Users who observe it on their systems should not trust it. The correct way to deal with Windows Antivirus Booster is to eliminate it from your operating system.

Windows Antivirus Booster originates from a family of fake antivirus programs called FakeVimes. Previous variants were named Windows Antivirus Helper and Windows Antivirus Tool. Cyber criminals responsible for releasing fake antivirus programs from this family employ identical user interfaces and functionality, merely changing the names of variants distributed.

To avoid computer infection by such fake antivirus programs, do not trust online security warning messages indicating security infections and offering installation of security software, supposedly to eliminate the security threats. Other safe computing tips include using antivirus and anti-spyware programs, and keeping installed programs and operating systems up-to-date.

It is difficult to determine sites are genuine when the Hosts file is modified. To fix this, please download the Microsoft Fix It tool, that restores your Hosts file to the Windows default. Run this tool when downloaded and follow the on-screen instructions. Download link below:

Summary:

The fake antivirus programs (also known as "rogue antivirus programs" or "scareware") are applications that tries to lure computer users into paying for their non-existent full versions to remove the supposedly detected security infections (although the computer is actually clean). These bogus programs are created by cyber criminals who design them to look as legitimate antivirus software. Most commonly rogue antivirus programs infiltrate user's computer using poop-up windows or alerts which appear when users surf the Internet. These deceptive messages trick users into downloading a rogue antivirus program on their computers. Other known tactics used to spread scareware include exploit kits, infected email messages, online ad networks, drive-by downloads, or even direct calls to user's offering free support.

A computer that is infected with a fake antivirus program might also have other malware installed on it as rogue antivirus programs often are bundled with Trojans and exploit kits. Noteworthy that additional malware that infiltrates user's operating system remains on victim's computer regardless of whether a payment for a non-existent full version of a fake antivirus program is made. Here are some examples of fake security warning messages that are used in fake antivirus distribution:

Computer users who are dealing with a rogue security software shouldn't buy it's full version. By paying for a license key of a fake antivirus program users would send their money and banking information to cyber criminals. Users who have already entered their credit card number (or other sensitive information) when asked by such bogus software should inform their credit card company that they have been tricked into buying a rogue security software.
