I seem to not be able to get rid of WincodecPro trojan.
Kaspersky, Malwarebytes and Spybot all seem to not even see it (all updated constantly).
I tried Combo-Fix (http://www.forospyware.com/sUBs/ComboFix.exe) as well. It seems to clear things up (odd icons are gone, resolution is fine, sound is back). However, once the machine is reboot problems are back: fatal error message icon on taskbar, resolution change, I am not able to look at Task Manager, etc..
Please advise if you can!
