After installing the latest version of Kaspersky Anti-virus, I can no longer receive e-mails.

I can send e-mails, but I can't receive any and they do not get copied to my Sent folder. I have two accounts (using the same Thunderbird installation and the same IMAP server) and both have the same problem. Thunderbird no longer asks my for my passwords and after a while I get a message that says only that the connection has timed out. Before the connection times out, the text that appears on the bottom bar says Checking mail server capabilities. On another thread, someone suggested logging into the account vis a Web client and deleting the oldest undownloaded message from the inbox because it could be a problem with the e-mail that blocks Thunderbird, but all my undownloaded e-mails were received after the problem started occurring.

I recently installed the latest version of Kaspersky Anti-Virus, so I'm suspecting it's blocking the incoming connection. I tried to re-install Thunderbird to see if it would work around Kasperky or tell me what I should do to get it to make an exception (or something like that). No such luck.

The Kaspersky support services don't seem to be worth anything so I don't think I'll get any help from their end.

Any help from here would be greatly appreciated,

Simon

I do not know how server traffic scan works, but I do know what heuristic analysis is. That is examination of code and dumping something containing code that is normally used in viruses.

Thanks. It looked very promising, but, unfortunately, the information that seemed relevant only applies to Kaspersky Internet Security.

My problem seems to be with the Mail Anti-Virus part of Kaspersky Anti-Virus. When I disable that completely, Thunderbird works fine, but I'd rather not disable the whole thing.

Does anyone know which setting I should change to allow Thunderbird to download e-mails while still having protection from viruses and other threats that could come with them?

I've attached a screenshot of the advanced settings.

I'm guessing the problem is the server traffic scan, but that also sounds like the most important thing.

Why connect to MS Office Outlook? What has that got to do with Thunderbird? Why scan outgoing mail? If the computer has no viruses, there will be none in outgoing mail.

Beats me, lol. I wondered pretty much the same thing when I saw those settings. Unfortunately, they're not the ones causing the problem.

Does anyone know if it's safe to disable the server traffic scan?... Will it create a giant hole in my computer's protection?

And what's a heuristic analysis? Is that good enough on it's own, without the traffic scan?

Sounds like the heuristic analysis is the only thing I really want it to do to my e-mails.

Thanks!
