-Look in the logs, and tell us what has been blocked.
-Disable "block unknown applications while comodo isnt running". In defense+ settings.
Or move the avast folder to "trusted files" (mark, include sub folders).
Thats the easiest way.
Avoid trainings mode. Its learns everything what tries to run. Thats not safe.
Defense's log screen only said AvastUI and Peerblock partial blocked, but the folders are all in trusted files (It's this the log or are there any Comodo log file in some folder in Win 7 x64? I can't find any txt log file in users)
I disabled "block unknown applications while comodo isnt running" and it works now! I have Fw + Defense in Safe mode, and Avast free Antivirus running. Peerblock driver starts ok now.
Thank you very much to both of you.
