Have to admit defeat on this one and ask for help (have never failed to fix friends computers, bit out of practice at present and this one has got me stuck). Windows 7 btw.
If I uninstall a program - I get a virus blocked message from Panda Cloud. Comsrv.dll. Did a MBAM scan, it picked up a couple of files in the GAC (something like tmp\U in the path). Rebooted afterwards and bang - I then get the %hs file missing blue screen.
I have a recent windows image backup - so restored, after a restore MBAM doesn't pickup anything, but if I uninstall (a different program this time). Panda pops up again, and if I check the registry I find and entry pointing to comsrv (if I change back to winsrv the system can re-boot).
Just restoring again - to get back to a system that is not actively infected, but of course as soon as I uninstall (and possibly install) I will be.
Suggestions on how to go about fixing?
