GMail POP3 uses SSL protocol. I don't think that Avast scans encrypted traffic.
Come to think about it, it's definitely strange...since neither Avast ! 4 or 5 can scan secure connections, Avast! shouldn't be interfering with the connections.

correct for Avast 4.8 but i think V5 will
Even Avast! 5 cannot scan secure connection...it simply has a local proxy server which sits between the mail client and servers. At the moment, we are prompted to put the connection to non-secure one when Avast! 5 finds a mail client is using secure connection with servers. It's odd for the original poster to be able to receive email when he/she turns off Avast! since it must mean the mail client is using non-secure connection with Gmail... He/she needs to reconfigure the mail client in order for it to receive secure connection again. On the other hand, if the mail client is using secure connection in the first place, the traffic shouldn't be interfered by Avast!, at all.
Is he/she using Outlook plugin?
What is your mail client, vinnyavaster? Are you using Avast! 4.8?
