exact identification is important for relief from false positives and
also from false negatives with polymorphs...
exact id is more about an increased degree of certainty about the
diagnosis than about avoiding screwing up the disinfection... false
alarms are more of a problem than mistaken identity (it's a very big
problem with some scanners... and false positives will always be a
problem with scanners that don't do exact identification...
take a look at vesselin bontchevs paper on the maintenance of a virus
zoo, in it he praises f-prot (this is before he started working there)
for being the best at identifying the family to which a virus belonged
(and this is despite f-prot's exact id capabilities)...
don't forget that most scanners wear two "hats" now... the virus
specific hats and the heuristic hats... varient detection is better
relegated to a heuristic process than to relying on an overly general
virus specific scan string... it allows for both high accuracy when
dealing with known viruses, and as it happens higher accuracy for
varients (as the more specific scan string contains more information
about the virus to compare the varient to)...
... in AV, the code that gets control first wins... boot clean!...**
