Avast problem and question
Recently my computer crashed after downloading Feb.'s Security Updates. I had to do a System Restore in Safe Mode to get my computer back. Now, I can't get Avast to update. I updated and ran Malwarebytes, and it came up clean. I also updated SpyywareBlaster with no trouble. Avast scanned last night so it works. It just won't update. So, I downloaded the newest version. My question is: Should I remove the old Avast or just install over it? I think I know the answer, but I want to ask for opinions first. Can anyone think of a reason why it won't update?
