Nope,this IS a support forum,so feel free to ask whatever you want regarding avast!. You can also use Search function to check if the info was already posted.

Hm,i assume that DiamondCS’s RegProt blocked Startup values.
Turn it off,uninstall avast!,install avast! again. I’m not quiet sure how Regprot works,but its probably blocking new startup values set by avast! installer.
