avast is not so good...its update still improving..
I am using kaspersky...and when windows is loading...it really take sometime to load it... but update roks!
heard tat nod32 works well...gonna try
I'm using Kaspersky right now and it's hands down the best AV program I'ved used. I'm very suprised Mcafee made it to #2...it would be at the bottom of my list along with AVG. Symantec is a mid-range solution at best. Trend Micro is under-rated in this study.
I have Norton SystemWrks 2006. Although robust, it is very invasive and often hogs the system. I removed it and opted for my lighter campus version of Symantec Client Security. McAfee is good as well, but I have not had any experience with BitDefender.
