Security Defense

It has become increasingly more difficult to distinguish between genuine security tools and rubbish rogue antispyware applications like Security Defense. This rogue antispyware application derives from the same family of rubbish rogues as Security Protection. It will cause your system to crash if you allow it to stay in your computer for any period of time. Even though Security Defense looks very much like a popular antivirus program, it is nothing of that kind. As a rogue antispyware application, this malicious computer threat damages your system with intention to rip you off. That is why you should not succumb to its persuasions to buy the full version of the program.

You will do yourself a favor if you destroy Security Defense the moment you see it in your computer. This rogue might be dormant for some time before it starts terrorizing you, but once it unleashes its wrath, then you are bound to experience a lot of annoying security alert messages that say things about your computer being seriously infected. What is more, Security Defense also performs a fake system scan and as a result finds a lot of viruses and errors in your computer. The scan should also be ignored, just like these fake security alert messages.

It will also annoy its victims with other irritating symptoms, some of which range from users being unable to connect to the Internet, or launch any type of application on the infected PC. Security Defense will also cause increasingly erratic system behavior and poor system performance.
