I have cleaned several computer of this recently and the only true and simplist way I have found is to Google a file called mbam-setup.exe. Download and run it.
This infection will disable your Anti-virus software until you run mbam twice. (run, reboot run again, reboot, run anit-virus software, twice. Remove everything it finds.
And the best part is it is totally FREE.
I hope this helps.
Birddog,
I pray that I may live to fish until my dying day. And when it comes to my last cast I then most humbly pray. When in the Lord's great landing net and peacefully asleep. That in His mercy I be judged, BIG ENOUGH TO KEEP.
