My problem …. For a week now ive not been receiving the automatic data base updates, also when I try manually downloading the up dates, when I click start updates
It say’s …. Downloading Updates Receive data…..but there’s no movement on the download bar, and after about One Minuet I get this message….Error Wrong Answer
Ive checked my ZA settings to allow the downloads, which seem to be ok,
I can update every thing else on my computer with no problems…?
When I first bought AVG Antispware it automatically downloaded the up dates with no problems..? and ive not added any new programs to my computer.

This is my first new computer so I am a newbie to computers; can some one please advise me what to do next please…? As I miss the auto update facility.

Thanks …… Mpenry
