I have actually seen malware uninstall a certain A-V program before. The weird thing is when I tried to install a new A-V program, it would start to install...then...nothing.
Seriously the computer would act like I never even installed the new anti-virus program.
The reason is that a Rootkit is blocking the installation of certain programs.
The solution is boot the computer up in safemode(F5) with networking, and download Combofix from www.bleepingcomputer.com
This A-V will enable you to now install your malwarebytes or AVG or whatever.
If this still doesn't help I urge you to read my Malware Hijacked tutorial.
Best wishes

ReplyDeleteI'll click the banner on top, even though I'm running Ubuntu/B|T5. You're welcome.
I think in that case using a Linux based bootable anti virus CD is the better option.
ReplyDeleteUse the Malware Rescue CD to get started. Its free.
