Once upon a time there was no DOS and no computer virusses. But since DOS was invented as a small OS which was easily extensible, virus writers saw their chance to easy spread their hacks. Although running a Linux system is relative safe, most of the files that most of you have available on your bbs are DOS based programs. And before you put them available for download, they should be checked for virusses. Macro virusses are a relative new danger, this can also hurt Unix/Linux users.
The problem is that there are not many scanners available that run native Linux, as far as I know there are only 2 scanners available.
The first is uvscan from McAfee. This program is not supported anymore because it uses version 2 .dat files and only version 3 and 4 .dat files are being made nowadays.
The other one is AntiVir/Linux made by H+BEDV Datentechnik GmbH. This one is up to date, can scan (Word) macro viri, scan inside archives. This version can be registered for personal use.
If people know of more Linux scanners, please mail me, so I can include it in this doc.
As soon as you have made a scanner available in the setup and the tic area files come in have the scan flag set, these files will be checked. Also uploads from users will be checked.
