On this page, you can specify which types of archive file are checked when scanning. Certain file types are scanned by default but you can also specify other types that should be scanned by checking the appropriate box.
By clicking once on any of the default file types in the list, you can see a description of that particular type of file at the bottom of the page.
If you want all archive files to be scanned, check the box “All packers”, however, this may significantly increase the scanning time.
