What is AVScan:
AVScan is a scanner that scans for more than 4500 virus signatures,
not including the other special identification methods it uses!
These methods are used to detect polymorphic viruses, such as MtE,
TpE, NED, Tremor, Girafe, Uruguay to name but a few. These viruses
are marked with (encr.) or (encrypted).
The purpose of this release of AVScan on CompuServe is to receive
some feedback on possible false positives and its network features.
The last version of AVScan on CIS was nine months old, but
AVScan is updated monthly in Germany (and weekly by BBS!) and we will
release future versions if time permits.
We've added a long list of exciting network features, such as
broadcasting, server logout, date-file and so on. More
features are under construction, but it seems that not all
possibilites of NetWare are published by Novell :-).
Parameters:
/? gives a complete list of command line parameters.

KNOWN PROBLEMS WITH OTHER PROGRAMS:
Usually all programs from Central Point (CPAV and MSAV) do NOT
cipher their scan strings (either memory and program file) which
makes it easy to patch these programs. False positives are
likely to occur. We've had an enormus outbreak of Tremor in
Germany during the last four months. Did you know that Tremor
specifically switches the resident part of CPAV and/or MSAV OFF!
If you receive an virus alert in memory, please check that you are
NOT running CPAV or MSAV: common messages are Vienna-634 or Youth-
Silence.

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:

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 keep us busy to implement new recovering methods
than to build an English version. I'm sorry about that. This
version of AVScan is supposed NOT to work on systems equipped
with German versions of DOS - while the German version of AVScan
does. Users inside Germany should get a licensed version.
We're thinking of bringing AVScan to North America. Ideas
welcome. You can contact us:
