Smart Security

Smart Security virus will pretend as an anti-virus application in order to cheat computer users and hide its true identity and purpose. Coming from the authors who also created the infamous Security Tool, it has the same method of spreading itself; most common is the use of fake online virus scanner. Typically, Internet browser that redirects to fake web sites is a sign of Trojan infection. The Trojan’s main objective is to propagate Smart Security virus. It modifies Internet browser settings and adjusts default home page settings for a malicious purpose. Once landed on fake online scanner, the site runs automatic diagnostic on the computer. As expected, it will discover a bunch of threats and security risks and advice to install Smart Security.

When inside the computer, Smart Security virus modifies your system files and registry. Embedding its own value will routinely run the bogus software every time Windows starts. Again, it will launch a virus scan, but this time it will perform local detection.  Consistently, it identifies similar threats.  Then, it shows an alert to convince victim in acquiring Smart Security activation code or registration key. Since the program is rogue, we never expect it to be fully functional security software. Smart Security author’s sole purpose is to gain earnings by deceiving computer users.
