Scan of compound files

A common method of concealing viruses is to embed them into compound files: archives, databases, etc. To detect viruses that are hidden in this way a compound file should be unpacked, which can significantly lower the scan speed.

For each type of compound file, you can select to scan either all files or only new ones. To make your selection, click the link next to the name of the object. It changes its value when you left-click on it. If you select the scan new and changed files only mode, you will not be able to select the links allowing you to scan all or new only files.

You can restrict the maximum size of the compound file being scanned. Compound files larger than the specified value will not be scanned.
