Speaking of Norton, I was doing some consulting for a lady Realtor who knew absolutely nothing about computers. She bought a laptop, a printer and a router. She didn't even KNOW she already HAD a router!! Anyways, I set up her system, got her a copy of AVG and installed it. I TOLD her that it would conflict with Norton, but just ignore it and when her trial period of Norton expired, to uninstall it (or call me and I would). Instead of calling me, she called the Geeks Squad to fix Norton!!
Oh well, I guess if she's THAT stupid, I didn't really want to deal with her.
AVG has never caused me any problems and it's FREE for personal use. There are other good ones out there, too. Why pay for bloatware when something is out there for free and is better??
