I have been wanting to change from AVG to Avast, but 1 thing bothers me, with everything I have read here, it says that avast cannot scan gmail since it is SSL protected. But, AVG can do it through this setup:

could avast use this approach? Please let me know as I would love to make the change, but want my gmail accounts scanned.

I’m sure someone will correct me if I am wrong, but I think it should be possible it you manually setup the email scanning in avast4.ini. It could be that on NT systems avast will reset the options since it is setting up the email checking transparantly.
I’m not sure on this and I can’t test it since I don’t have gmail.
Hi NormandieFrance and welcome to the forum! read here and see if this does the trick

darth.mikey,
I just glanced at the link, I will have to take some real time and search it out. Looks complicated though. Thanks for taking the time, I will see what I can figure out.
Have a good day,

No, it’s not possible, unfortunatelly. Gmail uses SSL (Secure Socket Layer) connections and avast mail scanner doesn’t support SSL.
But take a look here: http://forum.avast.com/index.php?topic=10428.0 to see how to set up secure email with avast!.
Since SSL/TLS e-mail is encrypted and decrypted in the client, external virus scanners (including avast!) can’t read or scan it.
The solution is to pass e-mail in and out un-encrypted from your client (Outlook Express, Thunderbird, …) to a proxy program (Stunnel) that does the actual ssl or tls encryption/decryption of the pop3/smtp e-mail and communicates directly with the ISP server on the appropriate ports. Another drivers (OpenSSL) are need as a library of encryption/decryption routines.
