Been running this for about a month now. Sorry, Symantec, you've lost a customer. This is the heaviest app I have evar seen! I was working on my desktop the other day, and couldn't figure out why my performance was suckin'. Took a quick peek over at the Task Manager, and there it was...Norton Anti-Virus had maxed out my processor. And it stayed maxed out for some time. I wasn't downloading anything, and I wasn't scanning anything. I checked online, and many other people are complaining about the same thing. I've read a solution that suggests just not running the runtime scanner, but that seems a little drastic. I kind of like having a real time scanner. So, I've tried AVG on my machine, and it's great. Not so heavy, and seems to do the job just as well.
Good job, AVG.
