- What is AVScan:
-
- AVScan is a scanner that scans for more than 4200 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.

- Bootsafe.Exe
- ============
- Older versions of this program did not decrypt their scan
- strings properly. Delete it and replace it with a newer version.

- 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:

-
- 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:
