I'm glad AVG is in the lead, just because I believe it's the best software out there.
Over the years I've run McAfee, Norton and Kaspersky and honestly, I don't think any of them were worth the money. Furthermore, I much preferred AVG to all of them. It gets the job done, it's free, and it has frequent updates. You can't go wrong with that
I defintely prefer panda but its not there i used it for 4 months approx and never had a prob with any viruses others i tried i always had such as AVG etc...
