Antivirus: Scan malicious code in double zip archives ?

AndiS
We received today a double Zip compressed archive file with malicious code by email. 
The file was not recognized by the UTM as malicious code. 
Scans the UTM ever double packed archive files ? We have activated the 'Dual Scan' option, but there are no option for the 'scan depth' of an archive file.

    Andi, the person that opened that zip needs to learn a bit more caution.  I can't imagine anyone being foolish enough to open a suspiciously double-zipped file.  You do have the option to 'Quarantine unscannable and encrypted content', but that requires more effort by the administrator - hopefully, your manager understands that.

    Then again, if this is at home and one of your kids got this, my heart goes out to the child.  I'd be glad to take a look at the email headers and report the criminal in that case.

    Cheers - Bob
