Nope, don't agree. Norton definitely slowed down my pc, no doubt but not McAfee that I have noticed. Sorry to be misleading about Limewire. It was the initial page that showed up as safe. I didn't go any further but if I had, McAfee would have picked up on it as it does anything else dodgy. I have never installed anything else with McAfee, not anti spyware, nor any other protection. AVG is fine too. The point I am trying to make is that if you don't download, you don't have a problem, unless it is from Adobe, Java or big trustworthy companies. It is easy to download stuff without even realising it. Sometimes you get pop ups warning about spyware with options to clean or cancel. To click on either of these can unleash all sorts of rubbish as I found to my cost. I had to get my son to clean up everything
When in doubt, click top right hand!
