The Year in Review
As the year comes to a close ... it appears that Trojan.Zlob/Codec remains the #1 threat. This is mainly due to the coordinated effort of the Malware writers and the Rogue Anti-Spyware community ...
While the detection rates have become better for the commercial Antivirus/Antispyware products, the "freeware" versions have failed to keep pace and are no longer recommended as a first-line of defense ...
The huge rise in the amount of "Rogue Anti-Spyware products" really surprised me this year. Even exposing these fakes has done little to stem the tide ... what I would like to see is all the "Mag" sites run several reviews on these bogus products and get the main-stream media involved in exposing all the parties involved.
So folks remember it's important to keep all your software updated, as the trend now is to attack the 3rd party products as the malware writers are finding it harder and harder to attack Windows itself.
I'll leave you with the following from August of this year ...
"The most interesting part (for me) however was the "Defense Evaluation / Blacklisting" part. When applied on their dataset the very famous hosts file maintained by winhelp2002 blocked all infections, although it contained only a minority (12%) of the domains." [source] (emphasis added)
