MalwareBytes Anti-Malware.v2.

From the developers...

(Malwarebytes Anti-Malware Free utilizes Malwarebytes powerful technology
to detect and remove all traces of malware
including worms, Trojans, root kits, rogues, dialers, spyware and more.)

This is one of the best programs we have used to clean out infections
We like this and install it on all computers we work on.
We set it up as a stand alone scanner not a real time scanner.
We have never heard of a false positive detection
That Doesn't mean there hasn't been any,
Just we haven't heard of any.
Free version differs from paid version by not being able to schedule scans.

Installing is by double clicking the .exe

During Installation uncheck the option to try the Pro Version when offered.

(we are only interested in free versions)

Clean Install, No other software is installed.

All other settings I would leave at their default state
but you may wish to change some of them.

If you have trouble getting MalwareBytes Anti-Malware to run
