I'm not sure if I should be asking this in the Email forums or in SpamBlocker, but since I am using SB3 I thought I would try here first.
Due to the increase of viruses/trojans being sent out inside of zip files that clamav is not detecting, is there any way to block .exe and .com files that are compressed in zip files?
They're getting through clamav but a few hours later when I resend the effected email to a test account, clamav then detects the virus. Clamav is set to update hourly and I believe they are new viruses or variants that arent added to clamav's database for several hours.
On clamav's defense, they also arent being detected by either Microsoft Security Essentials or Norton AV 2010 right away but a couple hourly updates later, they are. (Only given the option of "this file is suspicious, send a copy to us" prompt when I scan them manually.)
