What is Prime Shield?

Windows Prime Shield is a fake antivirus program, which employs fake security threats detection to scare unsuspecting PC users into believing that their operating system is infected with high-risk malware. This program is created by cyber criminals who use 'exploit kits', malicious websites, and fake online security scanners in order to distribute this rogue antivirus software. After successful infiltration, Windows Prime Shield blocks the user's desktop and continually performs fake security scans, which imitate the detection of various security infections. To remove the supposedly-detected malware, this bogus software demands activation of 'ultimate protection' (by purchasing a full version of the software).

PC users should be aware that Windows Prime Shield is a scam. Purchasing the license key is equivalent to sending your money to cyber criminals - you will lose your money and your computer will remain infected with a fake antivirus program. This fake security scanner originates from a family of rogue antivirus programs called "FakeVimes". Computer users who observe Windows Prime Shield on their desktop are dealing with a fake antivirus program - ignore the fake security scans and do not purchase the useless license key. This is a scam.

Previous versions of this rogue antivirus program were named Windows Prime BoosterWindows Virtual Protector, and Windows Accelerator Pro. The aforementioned programs merely imitate the behavior of legitimate antivirus programs - they hold no virus definition database or virus scan engine. Note that these programs mimic the detection of identical security infections on all computers infiltrated. To avoid system infection with Windows Prime Shield, keep your operating system and installed programs up-to-date and use legitimate antivirus and anti-spyware programs. Do not trust online security scanner pop-ups, which scan computers for security infections and offer download of antivirus programs in order to eliminate supposedly-detected security infections. Computer users already dealing with this rogue antivirus program should use this removal guide to eliminate Windows Prime Shield from their computers.

Step 4

After removing this rogue software, reset your Hosts file. Do not skip this step, since Windows Prime Shield modifies your Hosts files and you will encounter browser redirect problems if malicious entries are not eliminated.

The Hosts file is used to resolve canonical names of websites to IP addresses. When it is changed, the user may be redirected to malicious sites, despite seeing legitimate URLs in address bar. 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.
