Security Guard Removal

Security Guard is a rogue spyware program that is related to the well known fake security software Cleanup Antivirus. Security Guard tries to trick users into purchasing its license. It enters a user’s computer via Trojans or other malicious software that download and install Security Guard. Once installed, this rogue software creates a number of harmless files on the hard disk. Then it will endlessly perform fake system scans and return results and flag the above created harmless files as security threats. This is an aggressive technique used to stop the user from trying to manually remove Security Guard. This rogue software then proceeds to insist that the user should buy a license to the ‘full’ version of Security Guard, claiming that the currently installed ‘trial’ version is inadequate to clean the system of the falsely generated ‘threats’. Whenever the program is run, it will enforce this request through its GUI and through various pop-ups. However, the so-called ‘full’ version has no capability whatsoever to scan or clean your computer, and you should never fall for this trick and buy the software.
