I found that Kaspersky Internet Security 2009 to clean virus/trojan/malware isn't easy as the previous version.

KIS 2011 does not slow down my laptop but it does not clean infection. It detect, scan and reboot, could not delete at all although I keep click the option to delete it. Prompt me a few times. Crap!

This version of 2011 is real screwed up, remind me years ago of Norton. Can detect, can't delete. Crap! 2010 is better although 2011 has better features. Pretty disappointed, shall revert to 2010 and wait for new version
