Fix Slow Computer: spyware, trojan horse, virus removals

What is BackDoor-Guard.com?
BackDoorGuard (www.backdoor-guard.com) is a browser hijacker, the imitation of Windows Security Center. It informs you the following:
“You strongly need to FIX this problem! If you don’t do it - all the information from your computer might be deleted! Press the button below to check for all harmful programs and viruses from your computer and get help to delete it”.
The purpouse of this message is to scare users and force them to buy rogue anti-spyware applications or to call to paid telephone number (2.5 $ per minute) for “technical support” or “instant access”. Backdoor-guard.com results from Zlob trojan and may be difficult to remove manually. In addition Zlob can open browser security holes to download new spyware. Use Backdoor-guard.com and Zlob removal tool to delete these parasites from your PC.
