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 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 do so, use the link next to the
name of the object. It changes its value when you left-click on it. If you select the mode of scanning new and changed
files only (see page 76), you will not be able to select which types of compound files are to be scanned.
You can restrict the maximum size of the compound file being scanned. Compound files with the size larger than the
specified value will not be scanned.
Large files extracted from archives will be scanned even if the Do not unpack large compound files box is checked.

1. Open the main application window and in the top part click the Settings link.
