Support:
========
Support for AVScan is provided on an as is basis if time
permits. Since we make our living out of AntiVir IV, our comercial
virus remover (not a simple deleter!), you can reach us ONLY at:
CompuServe 71310,3143
InterNet 71310,3143@compuserve.com
Fax ++49 7542 52510
Background:
===========
AVScan is based on the algorithm behind AntiVir IV, which scans
for viruses in destroyed or damaged files. Some viruses do not
infect all kind of files quite easily. They usually have big
problems on certain files.
Scanning and removing viruses on infected files is usually quite
easy (advertisment: we can do it), even for encrypting viruses.
The problems are damaged files where the virus overwrote parts of
the host file. We take this seriously and built a scanning
version into AntiVir IV. This special feature enables the user
to scan for virus identities or signatures in damaged files.
This algorithm is the engine within AVScan and used within
AntiVir IV. AntiVir IV is a German product and available in
German only. Please don't ask about an English version - new
viruses keeps us too busy to implement new recovering methods
than to build an English version. I'm sorry about that.
Anyway - have fun and joy. You can contact us:
