5.10.228257.2253 signing issues

Just updated to 5.10.228257.2253 last week. Ever since then, Comodo Firewall continually complains that the following executables aren’t signed

symerr.exe (symantec antivirus error reporting)
wbem.exe (Web Management)
wmiprvse.exe (Windows Utility)

I’ve added them to the trusted file list but it doesn’t stick. Next time the app runs, I get a popup.

Did a clean install and the problem seems to have gone away.
