i too am having an issue, in the last couple of days my avast wont update the virus protection. Im wondering is there an issue with this or my pc. i have tried rebooting and using the repair in remove/change program features. it come up with an error of: ERROR PROCESSING PACKAGES. PLEASE USE FULL UPDATE.
i am using the current version of avast, and after rebooting it wont go past initializing when trying to update
