Hi, I've tried several fixes for this issue...
I get a notification saying definitions need updating. I click on update but after few seconds I get 'Http server returned error'
I have tried Avast Repair, also I used avast clear in safe mode then re installed latest version...these didn't resolve the issue.
Manually downloading the update file I was able to update the virus engine...
I am using:
Windows 7 Premium Home Edition(64-bit)
Avast Free Antivirus - Program Version 11.1.2253, definition version 160212-0 no. of definitions 3,260,218
Spy Bot Search & Destroy
CcCleaner
Any help or suggestions would be appreciated...
