- What is AVScan:
-
- It is a scanner. It now scans with about 3100 signatures for
- viruses, not couting special methods. Special methods are used
- for polymorphic style viruses like MtE, TpE, NED, Tremor,
- Girafe, Urugay to name a few. These viruses are marked with
- (encr.) or (encrypted).
-
- The purpose of this release of AVScan on CompuServe is to get
- some feedback of false positives and the new network features.
- The last version of AVScan on CIS is now rather nine months old.
- AVScan is updated monthly in Germany (weekly by BBS) and we will
- release future version also, if time permits.
-
- We've added a long list of exciting network features, such as
- bradcasting, server logout, date-file and the like. /? gives a
- complete list of command line parameters.
-
-
- 1.26 Signature for CRUNCHER and other viruses added
- 1.25 New virus signatures added
- 1.24a Scrambling of a temporary work buffer added due to LZExe
- 1.24 New virus signatures added
- False alarm with inhouse developed cobol programs
- fixed. Scan string was ZK 900 (A)
- 1.23 New virus signature added (same emergency)
- 1.22 Two new bs-viruses added (emergency-on customer demand)
- 1.21 Signature for DAME added
- 1.20 New virus signatures added, mostly polymorphic
- 1.19 New virus signatures added
- Fixed discrepancy with file count and directory count between
- logfile and screen display
- 1.18b False alarms with two PC-Magazine utilities fixed. LOCK.COM
- and UNLOCK.COM were flagged as containing MtE-unencrypted.
- 1.18a Fixed bug which stopped AVScan from scanning subdirectories
- on diskettes when in manual mode (/M)
- 1.18 New virus signatures added
-
-
-
- KNOWN PROBLEMS IN 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 pathc 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.

- Got a nice review in Virus Bulletin 1/93. However, they found
- some other programs, which AVScan 'flags' as infected:
-
- Virex-PC V.2.3
- ==============
- 570
-
- Vi-Spy Version 10

- 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

- 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
- German versions of DOS - while the German version of AVScan
- does.
-
-
- We're thinking of bringing AVScan to North America. Ideas
- welcome. You can contact us:
