How's your computer behaving now ?

The pop-ups have disappeared. Everything seems to be working well.

Malware is gone 


It is necessary to uninstall the ComboFix :

• Click Start (or ) then Run.
  
  
  On Windows7 or Vista you may use Start Search field if Run is not available.
  
  
• In the line of text type in (Copy) the following:

Code: [Select]

ComboFix /Uninstall

Note that there is a space between " ComboFix " and " /Uninstall " .

• then click OK (or press Enter ).

Wait for the uninstall process is complete.




Run OTL and hit the cleanup button.

I've uninstalled combo fix. I'm having an issue when running games where they lag when they did not before the infection. Would it have something to do with the messages about not finding sbmpar.dll and wmdvi.dll on start-up?

[argus]

Try this (sfc /scannow command)

The sfc fix did not work.
Any other clue as to what it may be?

[J0Jl]

I figured out what was wrong with my wmdvi.dll. It's infected with tojan.midhos. Is there a way to get rid of the virus from the program without removing the whole thing like Malwarebytes seems to be doing?
