Can antivirus detect infected ZIP files?

Antivirus like other apps on your PCs, are programs that are designed to perform certain tasks. If your antivirus software comes with the ZIP scan ability, then it will perform the actions.

However, even though some antiviruses claim to scan ZIP files, and archives in general, some of them fail to detect infections.

Moreover, some antivirus need to temporarily decompress the contents of the ZIP file to scan them, which is advantageous for the ZIP Bombs. While other antivirus software only scan the file contents after fully extracting them.

Furthermore, antivirus software can try to detect malware certificates that it is trained to scan. In case some new malware is in the market and its signature is unknown to the antivirus, then it could let that malware pass through.
