Hello All,
I’ve Avast Premier on my windows laptop. I can’t actually open the program at all (either by the program list or the shortcut) but I assume it’s running as the little symbol thingy in the right hand corner says I’m protected. Any thoughts?
Thanks.
Perform a repair of avast.
If that doesn’t solve it, perform a clean installation of avast.
Make sure any remnants of other any other previous installed av('s) are removed.
See http://www.ache.nl for links to instructions/tools.
Thanks will try that and let you know!
Think it might have been a Microsoft issue because directly after the Avast problem my Microsoft account became corrupted and wouldn’t sign in. I deleted the account, started again and Avast updated and is running fine! 
Thanks for your help.
You’re welcome.
