I have gone into the account, forwarded myself the offending email, and when I download the attachment, all the other AV clients pick it up as a virus of sorts. When put into Thunderbird, I can easily find some of the files SEP lists, so I know they're not false positives.

Same file (Well, two copies of the original mbox format file).

(There are other factors, like ease of use, deployment, firewall, scanning, etc, but those two are the most important ones.)ĮDIT 7/2/14: This is what I mean when I complain about the scanning. Is it so hard that I find one that does both?

Scan and remove any files that did get through (Zero Day Hueristics, etc) that are stored in Thunderbird's mailbox files.Ĭurrently, only SEP will find viruses inside the Thunderbird file, and only Avast does scanning incoming IMAP properly.

Scan incoming emails, so that viruses and such don't even hit the mailbox.

This year, SEP, Webroot, Malwarebytes, Avast, VIPRE, and ESET were on the testing table, and none of them fit two of the largest requirements I have: As our antivirus contract nears renewal, I always peruse through the options out there to make sure we're getting the best program for our money. I recommend you to turn this off if you value internet privacy.Hello everyone! Bit of a pickle here. There is a checkbox in “preferences” in Avast that says “scan secured connections”.

(2) Unsecure website certificates (maliciously exchanged, cracked or shared with third-parties) will be accepted by your browser and the whole concept of secure, encrypted and authenticated connections is ignored. (1) Man-In-The-Middle attacks by any person exchanging the website's keys to their own so that they may tap in on your connection will go unnoticed by your browser. This completely compromises internet privacy. There is no other way for Avast to decrypt the connection than to generate its own certificate with a known derived decryption key, then signing them with a custom Root Certificate from Avast installed on your system. Scanning encrypted SSL/TLS sockets requires that Avast can decrypt the connection.

This is happening because as others described, the Mail/Web shield needs to be able to scan your web traffic before it is saved on your system / does any harm. If it worries, you, you can disable this behavior - go to Settings>Active Protection>Web Shield>click on "customize" and tick the box next to "Disable HTTPS scanning." If you do this, avast! won't be able to proactively block malware on HTTPS sites.

Whether this behavior presents additional security issues is debatable but I don't think it's something you need to be deeply concerned about - after all, your own antivirus software is doing the man-in-the-middling, not a malicious party. I'm guessing this is what avast! is doing.

The solution that many antivirus programs use is to install its own SSL certificate as a root certificate so that it can essentially man-in-the-middle all HTTPS traffic to scan for malware. This presents a risk because if you download a virus, the antivirus software won't know about it until the download is finished and the virus is already saved to your hard drive, allowing criminals to bypass the "live defense" features of AV by simply hosting the malware on an HTTPS site. As useful as it is, HTTPS presents a bit of a problem to antivirus software because when you visit sites over an encrypted connection, your antivirus software cannot see what sites you're visiting or what files you're downloading, at least until the download finishes.

The whole goal of HTTPS is to prevent eavesdropping so that anyone monitoring your web traffic can't see what you're sending.
