>>promptly downloaded a virus onto the home computer
Well, I stopped writing them down after cleaning off Virus Number 22. I told him to be more circumspect with what he was downloading, then he went and downloaded another swack of them on Sunday when we were at The Game.
The problem was (as I see it) is that one of the viruses toggled the firewall switches before deleting/mucking up the firewall software/settings (a fairly common occurance). A firewall is just a software filter that allows/disallows access to something. (Think of it as like a parent who can hear someone crying in a crowded area and recognize the voice as their offspring.) Mostly firewalls run between an internet connection and a computer; typically you don't need them active on a network if there's a firewall in place because they slow things down.
But because you need two access points on a computer to run a home network, one with a firewall and one without, when the virus toggled the firewall switches, it then allowed unchecked access from the Internet and turned on the firewall to the home network which meant nobody could access the Internet or the main computer files. It's virtually impossible to fix when this happens without advanced help or wiping off your disk drive.
I fixed it after about 30 hours of reading, restoring, rebooting and changing software. And it's the last time I intend doing that.
I did find out a couple of things though.
If you're having problems with spyware, pop-ups, hijacks and stuff, you should seriously look at Microsoft's Antispyware software. Surprisingly, it's FREE and found like 280 items on the main computer that Ad-Aware, HijackThis and Spybot didn't find. You can set it up to run automatically at, say, 4:00 a.m. and it'll keep track of all of the junk that it finds. I'd actually pay for this software, which is saying something I guess.
If you haven't got a decent firewall, or installed Service Pack 2 on your Window's XP, get McAfee's firewall. In the last 16 hours, the firewall has blocked 327 different attempts to access the main computer. Most of these attempts are coming from China, Japan, Korea and so forth, but I didn't have a clue that the volume was this high. The computer's disk drive isn't running all of the time now.
