Q

The ability of antivirus software to scan zipped files

Since encrypted attachments cannot be accurately scanned by antivirus software, how about password-protected zipped (compressed files)? Can they be scanned?

No! Compressed or encrypted files cannot be read by antivirus systems while being transmitted. To mitigate this risk, antivirus agents are installed on systems so that when the files are uncompressed or un-encrypted they are then scanned.
