Which should I use? I get the Norton SS free with Comcast and offers more features than Norton 360 Suite. The McAfee comes with my computer. Which should I use?
Don't waste money on either of those suites. Windows 8 comes installed with Windows Defender and it does its job very well. Defender (along with some common sense) will protect you adequately and not bog down your PC like Norton and McAfee do.
Neither, I use Avast, refused to pay twice for an antivirus sub (use Norton on my laptop). It's kept my computer clean as a whistle, apart from that one time there was a rootkit, but it cleaned that up nicely once I figured out what to do. And then there was that Steam false positive, which was a false positive.
