Is there a rootkit tool for zeroaccess and Sirefef removal for 64 bit Win 7? Lots of people are running 64 bit OS and on my first round of searching have not found a product for removal. The latest attack by Open Cloud AV on a laptop modified the taskmgr to make it useless (copying a clean taskmgr to system did not work - I suspect the rootkit/FakeAV is playing with modal windows API's to hide taskmgr menu bar and tabs or just substituted a useless taskmgr) and finally disabled the trackpad - really bad stuff. I got it under control but I have a feeling because of system behavior that there is still a rootkit hiding somewhere.
