Windows Prime Shield is a rogue anti-malware scanner that delivers results of questionable (or completely false) accuracy. While Windows Prime Shield incites a sense of threat in the affected PC user, Windows Prime Shield also may block other applications or conduct other forms of mischief that Windows Prime Shield blames on fictitious PC threats. At the end, Windows Prime Shield demands money for a premium registration key, but malware experts have a better suggestion for dealing with Windows Prime Shield: disabling Windows Prime Shield and then deleting Windows Prime Shield with a legitimate anti-malware scanner.

A Prime Example of the Problems with Fake Security Programs

Windows Prime Shield is a member of the FakeVimes family and a clone of Privacy Guard Pro, PrivacyGuard Pro 2.0, Extra Antivirus, Fast Antivirus 2009, Presto TuneUp, Windows Security Suite, Smart Virus Eliminator, Packed.Generic.245, Volcano Security Suite, Windows Enterprise Suite, Enterprise Suite, Additional Guard, Live PC Care, PC Live Guard, Live Enterprise Suite, Security Antivirus, My Security Wall, CleanUp Antivirus and Smart Security. Although Windows Prime Shield claims to include a range of useful security tools, ranging from process managers to anti-virus protection, Windows Prime Shield actually is a threat disguised as a security product. Purchasing Windows Prime Shield doesn't hold any advantages for your computer, and malware experts warn that personal information transferred through Windows Prime Shield could be exploited by criminal entities.

Windows Prime Shield does imitate pop-up warnings and even system-scanning functions that are common inclusions in real security programs, but with one important difference: all of the threats detected by Windows Prime Shield are inaccurate. As added salt to this wound, any other attacks Windows Prime Shield implements may be blamed on these fake PC threats. Malware researchers find that you should expect many PC security suites and other programs to be blocked while Windows Prime Shield is installed, such as:

  • Web browsers.
  • Anti-virus software.
  • Update utilities for popular brands, such as Adobe software.
  • Skype and other instant messengers.
  • Torrenting clients.
  • Webcam utilities.
  • Apple's iTunes and other music managers.

Windows Prime Shield may continually search for and terminate the processes of these programs and others, essentially denying access to any unapproved software.

Shielding Your PC from the Brunt of Windows Prime Shield

Windows Prime Shield, also known as Rogue.Win32.GuardSoft, may be installed through JavaScript-based drive-by-download attacks, including fake system scanners and other scams. Websites that are risky or websites that have been hacked, along with some less than safe advertising networks, are the major methods by which these attacks infect new PCs. Even if your PC doesn't show any of the symptoms listed in this article, contact with anything resembling these PC threats should be treated as equivalent to a potential infection by threats.

Windows Prime Shield should be terminated prior to removing Windows Prime Shield, which will let you access any blocked programs that are necessary for your PC's safety (such as anti-malware tools). If Safe Mode is inadequate at doing this, you may feel free to resort to other methods recommended by malware experts, such as launching a peripheral device-based operating system. You also may attempt to use a free registration code on Windows Prime Shield before removing Windows Prime Shield, such as 0W000-000B0-00T00-E0001, 0W000-000B0-00T00-E0002 or 0W000-000B0-00T00-E0003.
