Windows Functionality Checker is one of the many fake security applications belonging to the FakePAV family of rogue anti-virus software. On the surface, Windows Functionality Checker resembles Microsoft Security Essentials. However, the resemblance stops there; Windows Functionality Checker has no legitimate security purposes or capabilities. Windows Functionality Checker is part of a popular cyber scam which relies on fake security programs that display bogus alerts and scans in order to make their prey think that their computer has been taken over by a severe malware infection.

Then, it attempts to convince the victim that these non-existent problems can only be removed with a useless “full version” of Windows Functionality Checker. This fake security program puts your computer at risk as well as your wallet and should be deleted with a legitimate, reliable anti-malware tool immediately. It is important to note that most malware does not attack alone and that the presence of Windows Functionality Checker on your computer may indicate that you have been infected with a Trojan designed to download and install malware. Malware in the FakePAV family of rogue security applications will often be distributed through fake video codecs and freeware media applications, as well as through malicious email attachments contained in phishing email messages.

What Windows Functionality Checker Actually Do to Your Computer

Although Windows Functionality Checker pretends to run a full scan of your computer system, there is actually nothing going on in Windows Functionality Checker’s authentic-looking interface. This program is merely designed to display constant fake error messages and to cause your computer system to behave erratically or poorly to enhance the illusion of a severe malware infection. Windows Functionality Checker has the capacity to close any legitimate security application that may pose a threat to its existence as well any kind of web browser, which may allow the victim to gain access to a solution for the Windows Functionality Checker infection.

Windows Functionality Checker also runs automatically whenever Windows starts up, which may give computer users a hard time when trying to remove this threat. Because of this, ESG security analysts recommend first staring up Windows in Safe Mode. This prevents Windows Functionality Checker from launching automatically, ensuring that you can gain access to your web browser and security software without interference from Windows Functionality Checker. Known clones of Windows Functionality Checker include fake security programs like Windows Passport Utility, Windows Debugging Center, and Palladium Pro.
