The key to Malwarebytes is that you have to run it in safe mode. When you get these virii, restart in safe mode and then run MB.
The thing with that, was that while malwarebytes could find the nasty stuff, it could not find/fix the root of the problem that was really the issue. The real trouble was in the corruption of WIN registry, the Win32 something. Malwarebytes would remove the virus, trojans, etc, but each reboot would kick in a new set of problems, and hijack the browser, and shut down the security system. Pretty clever little btsard, but finally I beat it with the help of MSFT.
Again, I am very impressed with the MSFT folks, and the outsourced group working from Bombay. They would not give up on me, and called me and emailed me several times to make for DARN sure, there was not a customer dismayed/lost.
I must say, from reading all these various posts about troubles, that the simplicity of just picking up the phone and having msft do it for free, is a HUGE peace of mind.
