How to remove Win32:AutoRun-BDI [Wrm]

I have a problem with a worm called Win32:AutoRun-BDI [Wrm]. From time to time my Avast antivirus informs me numerous times, that the malware has been detected and moves it to virus chest. It continues on and on. The worm tries to create .pif, .scr or .exe files in different locations.

I want know how can I remove it. Avast just blocks it, but the worm is still there hiding somewhere.

do you have…or use removable drive…or skype?
