yes, but their test bed is too small... with just under 400 total
viruses, last years test was a joke...

the scanners are not the problem with those tests...

i disagree... with that unreasonably small test bed, the chances of a
statistically anomalous set of results is quite high...

untrue, i don't listen to those types of tests either... the best tests
i have ever seen done were by (at the time) third party
individuals/organizations... they only managed to use about half of all
the known viruses but that is orders of magnitude better than the virus
bulletin test last year... there are several requirements for a good
test and one of the most important ones is a large and sufficiently
random test bed... this is a requirement of any statistical analysis...
if i went out and surveyed five people on their opinion of something,
would you trust the results? i wouldn't - that small a sample can't hope
to be representative from a statistical point of view... the virus
bulletin test had the same problem (though to a somewhat lesser
degree)...
... beware of quantum ducks... Quark! Quark! Quark!...
