Michele, Comcast is our ISP, and it gives us free anti-virus, spyware/firewall, and privacy protection services by McAfee. All I had to do was download all the software. It shows me a log of people/other computers trying to get into my computer during the day. It also automatically updates the anti-virus protection. The privacy protection won't let my son online unless he has my permission (after which I type my password in a dialog box.) Does your ISP provide such services? I know there are tons of software out there but I've always gone with McAfee (just habit), even before we switched to Comcast from AT&T dial-up a long time ago. Of course, I had to pay for the software then.
