Not wishing to start a argument here, but isn't like the only reason Kaspersky is rated above NOD32 because of it's user interface?
Well lets see;
kaspersky Anti-Virus 6, shines for its top-notch malware detection and disinfection rates. It boasts a 96 percent detection rate, and cleaned 86 percent of all items in our disinfection tests. It is also the fastest at delivering new signatures out of the eight tested programs, with an average response time of 0 to 2 hours.
Now lets look at NOD32
NOD32's overall malware detection rate wasn't stellar, however. When pitted against AV-Test.org's nearly 900,000-strong "zoo" of Trojans, viruses, and other malware, NOD32 caught only 90 percent, compared to the 96 percent rate of top performers Kaspersky Anti-Virus 6, Symantec Norton AntiVirus 2007, and BitDefender Antivirus 10. It fared surprisingly poorly with 32-bit Windows viruses (approximately 1 in 11 samples in the zoo), catching only 73 percent.
Well judging by http://www.pcworld.com/article/id,130869/article.html
it's not just a GUI or interface that makes it rated above NOD32. lol
