My avast pro suddenly has interrupted. I click the button fixing and the button for starting but it can’t restart.
What can i do?
Repair>> Open Control Panel, go to either Add/Remove Programs or Programs & Features, depending on OS.
Begin as though you are going to uninstall Avast!, but choose the Repair option.
It shows me the message:error processing packages, please use full update
WTF, never heard of that one ???
Anyway, on to a clean reinstall then.
Grab a new Pro setup>>http://files.avast.com/iavs5x/setup_av_pro.exe
Then grab this here>>http://www.avast.com/uninstall-utility
Now remove Avast! normally through Windows Control Panel. Then run the uninstall utility in safe mode. Once thats finished, you should be cleared to reinstall.
Thank you very much for your help 
Did it work?
I’ll take smiles as a yes, I suppose.
Anyway, your welcome. 
Yes it works!
