Why not testing more Amiga-antivirus products ?
  The selection of this products is a subjective view of the
  actual market. The selection of tested products represents
  common virus-scanners which were updated at least once
  in 1995. 
  Why we didn't test BootX-Recog: BootX is updated within
  its recog-file which makes detection of modern viruses
  like Crime etc. impossible.
  Why we didn't test Vscan: Vscan was not able to run without
  crashes in our testing environment.

Official release date of this test:

  The official release date of this test is the
  start of the CeBIT in Hannover on 8.3.1995.

Tested facilities of the products:

  This test mainly shows the detection rate of the products.
  User-interface, styleguide etc.. are no essential topics
  of this test.

V. Comments
The following are some peculiarities about the tested 
virus scanners. Those comments might be usefull to have 
in mind when selecting one of those products.

* Vectorcheck
  VT:   Checks some vectors, displays their names
  VW:   Checks many vectors, but shows only their offsets
  VZ:   Checks some vectors
  VC:   Checks some vectors
  SFAP: Checks only resident vectors

* Reporting functions
  VT:   Very good
  VW:   Had a bug in 4.8
  VZ:   Good, but includes Ascii control-characters
  VC:   Good, difficult to activate
  SFAP: Good, not saveable

* Bootblock data check
  VT:   Yes
  VW:   Yes
  VZ:   No
  VC:   Yes
  SFAP: No

* Integrity check
  VT:    Yes
  VW:    Only for the scanner itself, PGP signatures
  VZ:    No
  VC:    Only for the scanner itself, PGP signatures
  SFAP:  For files, (added as comment)

* Memory monitor
  VT:    Yes
  VW:    Yes
  VZ:    No
  VC:    No
  SFAP:  No

* Heuristics
  VT:    No
  VW:    No
  VZ:    No
  VC:    No
  SFAP:  Yes (only for bootblocks)

* Decrunching
  VT:    Yes
  VW:    Yes
  VZ:    Yes
  VC:    Yes
  SFAP:  Yes, the decrunch task executes some files !

Other remarks:

When some of the scanners remove a virus, they restart the scanning 
from the beginning - this is very inconvenient for owners of big 
hard disks.
However the repair method used by the other scanners can 
miss some files due to the change of the directory structure
that results after the repair.

VZ reports on the screen that it is performing repair even if it
is started without the repair option, regardless that in this
case repair doesn't actually occur.

When SFAP is run with the decrunch option, it executes parts
of the files in order to decrunch them. Unfortunately in some
cases this scan starts the virus in the file as has been verifyed
to happen with viruses like Crime1000, Commander-Link etc.
This makes the testing of this scanner extremely difficult.
For instance after the Commander-Link virus infected the whole 
test environment, we had to restore the original state from
a backup.After that we only tested the scanning capabilities
of SFAP only without decrunch, due to a lack of time for
