Security Defender is not legitimate security application. The program is totally scam that displays false information, detects fake infections in order to trick you into thinking your computer in danger. The fake antivirus will say that all you have to do in order to remove viruses, malware and trojans is purchase its full version. Important to note, the program is unable to detect and remove any malware and viruses, so do not pay for the bogus software! Simply ignore all that it will display you and remove Security Defender from your PC as quickly as possible!

Security Defender promoted through the use of advertisement which pretends to be an online malware scanner. This advertisement will state that you computer is infected and all you have to do in order to cure your computer is install the software.

SecurityDefender will also display various fake security messages and warnings that inform that your PC in danger.

However, like false scan results above, all of these security messages are just a fake and has been displayed to trick you into purchasing so-called full version of Security Shield. You should ignore all of them!
