As soon as it sneaks into the computer system and gets activated it would begin to try to scare the PC user with Warnings and security Threats of viruses and malware detected.

It can be used by hackers to record your keystrokes and web browsing history so as to steal you personal information.

However there is no licensed version and unsuspecting people would just lose their money and compromise the payment details to thieves and hackers. One of the victims said: I’ve recently acquired the Security Defender Virus and I can’t run any .exe files to get rid of it. I tried in both normal and safe mode with networking. Anytime I try to open malware bytes or rkill it comes up with a screen saying security defender firewall alert and lists the program i’m trying to open. It gives me two options “Activate” (to register my copy of Security Defender) or “Stay Unprotected”. I tried using a flash drive to open up RKill and MBytes but it still won’t let me run them.
