These are good. I use them. I use spybot ( http://www.safer-networking.org/ ) as well.
I have AVG ( http://www.avg.com ) for my antivirus. It's free if you don't have one.
And remember, if you already have antivirus software loaded on your machine (like McAphee or Norton or any other), remove them before adding a new one!!! Antivirus software does NOT play nice together!!! Also, if you are removing McAphee, using uninstall isn't enough. You have to go online and get a special tool to get rid of the debris it leaves behind. Find it at MajorGeeks. This issue has been causing people major headaches for years!!!
There are several good Free antivirus programs available. AVG has a good reputation as does Avira (which I use).
DeesHens: Sorry to hear your hard drive is having problems, but on the flip side I'm REALLY glad to hear you're doing backups!!! So many people never do and they lose so much when the bad happens. We have a portable hard drive that we use for backup. If the main computer goes south all we have to do is plug it into another one and we're ready to go. Actually... I have two... I keep one off-site in case there's a real disaster like a fire or theft. Is my geek background showing yet?
