You are cordially invited to try VDS 2.0 on your PC

                      DESCRIPTION & FEATURES
     VDS (Virus Detection System) is an anti-viral software package
designed to contain the spread of computer viruses by providing
early detection and quick recovery.  What distinguishes VDS from
other anti-viral products is that its operation is based on
analyzing viral behavior rather than just looking for known byte
sequences extracted from virus samples.  Therefore, VDS does not
require frequent upgrades.
     VDS uses a proprietary triple-pass verification technique to
catch the most evasive "stealth" viruses even when they are active
in memory.  Coupled with its blazing operational speed (thanks to
its optimized internal cache), VDS represents the strongest
software solution currently available.
     VDS (registered only) generates a customized device driver 
during installation.  The device driver barely adds three seconds 
to bootup time and catches all system infectors with ease.  It 
recovers vital system areas automatically.  The user is given an 
opportunity to embed his own message inside the device driver.  This 
message is displayed if a possible infection is detected.  Businesses 
will find this feature very useful since it can be used to prompt users 
to report any incidents as instructed by the message. 
     A unique feature of VDS is its decoy launching mechanism.  The
decoys are used to lure any viruses active in memory and to capture
them in a POV (Prisoner Of VDS) file for examination.  The captured
intruders can speed up diagnosis process since you will know which
virus you are dealing with or whether it is a new virus.
     VDS documentation rivals many books on computer viruses not
only by its readability but also by its technical content.  It
offers practical guidelines and a risk analysis test designed to
evaluate the vulnerability of your computers to viral attacks.
     The package includes a special utility program that helps
users to recover from all system infectors that target vital areas
of hard drives such as the master boot record.  Another program in
the package allows users to search network and floppy drives for
known viruses.
                      AVAILABILITY 
     VDS Advanced Research Group offers six different versions of VDS: 
trial, personal, academic, charity, business and complimentary.  Trial 
version is only $7 and can be ordered directly from the developers.  
It is also available on several BBSes and can be downloaded for free. 
Everyone is encouraged to upload the trial version of VDS to BBSes in 
their area, as long as the complete package with this message and 
documentation is uploaded.
     Personal version sells for $25 and can be used on as many computers as 
the user personally owns.  If the user chooses to become a registered 
user after ordering the trial version, the $7 is credited towards the
payment for the personal version.  Site-licenses for businesses can
be negotiated.  Business version allows all employees of a company
to use VDS on their home computers at no extra charge.
