P.S Another good site to find out more on “Common Vulnerabilities and Exposures (CVE)”
is http://cve.mitre.org

I am testing a AV named say ” ABC” .
There is another reputed AV say XYZ. A virus called say “XX” which is detected by XYZ , may be passsed undetected by ABC. How will we test AV ABC for various various definations. My understanding is vairus definations are available when a AV updated from AV server.

While testing , how do i get a affected files/data to test this definations?
How do i ensure that realaiablity of this file/data i am using for testing ?

“Get some good bets by reading comparative reviews of competing
products published by third-parties, such as PCWorld, Consumer Reports,
and MacWorld.
- – Hedge your bet by opting for a trial version, if available, and one
that you can upgrade to a full subscription without reinstalling.
- – Weigh effectiveness, performance, features, support and, lastly,
price-at most a difference of $30/year.
- – Verify that the product includes anti-virus, anti-spyware,
anti-phishing, anti-spam, a two-way software firewall, and automatic
online updating.
- – Performance and effectiveness are judged best by the results of
professional testing, like those performed by AV-test.org and
http://www.av-comparatives.org.”

Some other thing to consider are applicability to your industry and useability. And please remember that AV solutions are only a part of the multi-tiered security solution that you should have protecting your business.

Hope this helps!
