RE: How to remove a virus.
MBAM and other automatic scanners can't possibly remove all infections, most of the time.
As they only do the scans of viruses in their databases, they usually won't fix broken keys, hijacked dlls/exes, or Internet Browser settings, such as proxy settings. This is why most of the time after a user is infected with a Rogue AV, they can't use their internet because their proxy settings were mingled with by a virus. MBAM can remove the virus itself usually, but not always the damages that it leaves.
HJT isn't the best program for secondary scanning, and you shouldn't be giving advice on logs if you don't know how to.
Other scanners such as OTL, another manual removal, but far more complex than HJT is a good scanning program that will give a more in-detail report of the system, the drives, the user, the programs, modified files, etc.
