The comparative
was conducted in Feb/March 2007 on a sample of over
35600
infected files. Files were infected
with old and new virus, mildly
very harmful, worms, trojans and
similar. These files were unpacked
in a dedicated folder where they got
scanned by the different antivirus
systems.
Each antivirus
was set to operate to the top of its
heuristic and scan
potential. It is
important to note that in the
results enclosed below, the
slowing down of the
OS has not been taken into
consideration.
Every antivirus
has been updated before the test.
Since the
antivirus roundup of 2006, the
database of virus samples has more
than doubled. For some AV this
increasing did not make any
difference; in a few cases there
have been notable variations.

NOTE: The time for the
scanning concerns the scanning of the 35600 infected files. The scanning speed
of infected files can be very different from
scanning speed of files the are not infected.
In comparison to the
2006
comparative, we can easily notice that, despite
the virus samples have more than doubled, the
principal antiviruses maintain the same percentages
of recognition. In any
case, if there have not been changes in top
classification (except Panda, that improved both in
speed and in recognition), there have been changes
in the lower part; AntiVir PE has gone down,
slightly, while Norton and the open source ClamWins
seem to have been more penalized.
Unfortunately widening of the sample database has
not helped the free antiviruses; in fact - with
exception of AVS (Active Virus Shield), that has the
Kaspersky engine - they have all lost both in
percentage of recognition and in positions
(furthermore AntiVir has also become heavier than in
past), above all ClamWin, the only one that -
because of its license - could also be used for
business purposes.
Update: starting August
2007 AVS is no more distributed.
A notable disappointment has come from Comodo
Antivirus that, unlike the good firewall (always
free) of the same software house, not only arrives
distant from the first ones, but also from the last
ones. Probably in Comodo have assigned more
resources to the development of firewall than of
antivirus.
I also remember that the 1% of difference between an
antivirus and another begins to be meaningful,
because on some hundred thousands of circulating
threats, 1% of recognition in less means to be
exposed to some thousands of risks in more.
