I think I may have the same issue.
after one of the recent comodo updates I keep getting notifications for some windows exes
like dllhost.exe (shows COM Surrogate as the description) and
DeviceDisplayObjectProvider.exe
WmiPrvSE.exe
TaskHost.exe
wermgr.exe (Windows Problem Reporting)
it says the files are not digitally signed…
checking the Always Trust does not seem to stick…as the notification keeps popping back up
I’m also running 7 x64 without SP1
well I’ve had the issue where just a restart has fixed it previously
I had already tried that a couple times in this instance as well
either way…seems it may be fixed now. it doesn’t seem to be doing it anymore
