Hello, I have been using comodo for a while and haven’t had any major problems until I reformatted my system. I completely wiped my system and had to reinstall all windows updates. On SEVERAL updates, COMODO’s realtime scanner (I have it set to high heuristics as always) continuously flagged windows update files in the c:/windows/winsxs/temp/PendingRenames folder as the following : “Backdoor.Win32.PcClient.~a@97069727”. Sometimes the files could be quarentined, other times they could not. COMODO prevented these updates from being successful when it flagged these files as viruses.
i don’t know all the updates it flagged because I turned it off for a while, however I can say that while attempting to install Windows Vista Service Pack 1 (vista 32-bit) it flagged a file which resulted in the failure of the update. I suggest further testing. After turning off the real-time scanner feature, I was able to successfully install Windows Vista Service Pack 1 (32-bit).
