zip-tiedoston tarkistus, kun se sisältää toisen salasanasuojatun zip-tiedoston ?

Pystyykö F-Securen ohjelmistot tarkistamaan tuollaisen tiedoston tai varoittamaan puutteellisesta tarkistusksesta ?

How does F-secure check a zip-file containing another password-protected zip-file ?

Does F-secure warn user if it can't check the file ?

Simon

Someone will correct me if I'm wrong on this, but I think it would only tell you that it hadn't scanned the file if you do a manual full or 'target' (right click) scan, then read the report.

If the zipped file contained anything malicious, FS should alert you as soon as the file is opened.

All popular (including F-secure) antivirus-programs tell that the (original) zip-file is OK. None tells nothing about the contained password-protected zip-file. So, after unzipping the original zip-file user will have an unchecked zip-file in his machine and anything can happen. This is  practically equal to an unchecked crypted file.

The Password protected Zip-file may not be able to be scanned. On the other hand it is like @Simon says that the files are scanned when opened and blocked if found malicious. Files that are contained in a compressed file cant do any harm until they are decompressed and released in the system.
