win xp home sp3 here, Avast! free and outpost firewall.
Please can anyone say what Avast! process causes unsecapp.exe to start lately?
I don't really need some of the Avast! extras like browser cleanup, grime fighter, etc, so if unsecapp is called by one of those I will just turn that off.
Thanks in advance for any feedback.

Fwiw:
unsecapp runs here until it is stopped manually.
unsecapp can be stopped using process explorer, and does not restart until the computer is restarted.
I have renamed it to unsecapp._xe so it won't start.
wmiprvse.exe still starts like it always did, so that is not affected by the absence of unsecapp.
All other apps and processes seem to still work, but more time is needed to be sure.
