AVG: please post this question for me

[Chankama]

Unfortunately, AVG doesn't allow you to register until you download and install their program - which I don't want to do before I know more details of the product. One of you guys who own AVG, please post this question for me on their free forum?.. Thanks!

Title: (so their won't be duplicate questions)
"AVG definition update process secure?"

Message:

Hi guys.

Just have a quick question regarding the security of the virus definition update process. You can get them 2 ways:

(1) Run the auto-update from within AVG
(2) Download the definitions

Is either of these procedures "secure"? As in can an attacker force corrupt/malicious definitions on your system?

Only if the download channels are secure (e.g. SSL) or definitions are digitally signed will they be totally reliable IMO. Otherwise, some attacker "can" force their own definitions on you.

Can someone please provide me with more details as to what AVG does?.. Thank you!
