How to remove Security Antivirus (Removal guide)

Security Antivirus is a new rogue security program, also known as rogue antispyware application. The rogue from the same family of malware as Live PC Care. Security Antivirus is installed through the use of trojans that come from fake online malware scanners.

When the trojan is installed, it will download and install Security Antivirus onto your computer and register it in the Windows registry to run automatically when Windows loads. The same trojan will also drop several files with random names in %UserProfile%\Recent folder (ANTIGEN.drv, ANTIGEN.exe, cid.dll, CLSV.drv, DBOLE.sys, ddv.dll, ddv.sys, energy.tmp, FS.drv, PE.exe, PE.sys, runddlkey.dll, std.exe, tjd.drv). All of these files can`t harm your computer, but Security Antivirus will label them as serious computer infections.

Once running, the rogue will simulate a system scan and report above files as dangerous infections that will not be removed unless you first purchase it. Of course, the scan results is fake, because Security Antivirus is unable to detect or remove any infections. So you can safely ignore all that the program displays you.
