Kaspersky lost his leader position in Europe, since Norton 2010. It doesnt have Anti-Banner, but i think ADB or NoScript plugins(Mozilla Firefox) can fix it better then any anti-banner.
It is good that you use Nod32 now because you cant check detect of this AV

As i know in Poland and Russia, Eset is very agressive.
But absolutely leader in this world is Symantec with 6,15 Billions of dollars in the last fiscal year. Actually this corporation with over 17,500 employees has only 2 competitors. But they got together only about 4 Billions (McAfee and Trend Micro).
Some days ago was released Norton 360 v4.0
It has all technologies of Norton 2010, Backup (Symantec is absolutely leader in backup programms) and Tune up (Symantec bought PC Tools in the 2009 year, so it has technologies and methods of PC Tools programms.)
Also Microsoft used technologies of Symantec in Windows XP. Symantec is #5 as a Software company.
