Yesterday, I searched my computer for viruses, as I normally do, using Avast. It as usual found no viruses. I decided to also perform a boot-time scan, and then went to sleep. Earlier today I started the computer and the scan started as scheduled. When it was finished, Avast told me that it found something along the lines of "Win32.Rootkit-gen [rtk]" in directory $Recycle.bin which was "moved to virus chest". Having recieved a rootkit on another computer about 2 years ago, I downloaded the same utilities I used back then (Trend Micro anti-rootkit, MBAR, Spybot S&D, TDSSKiller, McAfee Rootkit Remover) which all showed the computer was clean. While I think I'm still infected by something malicious, I've noticed no adverse effects from the infection at all - no toolbars, popups, account hijackings etc.
How should I continue to make sure whether I'm infected or not?
Thanks a lot for taking your time to help me.
