Look out for a fake anti-spyware program with the name Backdoor Guard-this
misleadingly named program only pretends to protect your computer. Once installed, however, it opens a backdoor, so that the programmer can access your system.
If the victim restarts his system after installation, the trojan blocks your normal desktop and opens a website.

The victim then sees messages saying that there is a problem with the license and that a call to a long¬distance number is required. A PIN number is displayed on the website and you are instructed to enter it when calling. However, the PIN will cost €20 (approx Rs 1,190)! There's a quick way to rescue your computer: all you have to do is boot up in Safe mode and then delete the file 'locker. exe' in the Windows folder.
