Two Worm "Families" Make Up Most Botnets
JMoon writes "HNS has an article about the Sdbot and Gaobot families which are responsible for most botnets worldwide. These two families were responsible for 80 percent of detections related to bots during the first quarter of 2007. Other culprits, although on a much lesser scale, included Oscarbot, IRCbot or RXbot."
If you are stuck with dialup, get a friend to download the SP2 CD and burn it for you.
If you have DSL or Cable and nothing else on your LAN is infected, your NAT or other firewall should protect you from "out of the box" threats. As long as you stick to known-safe web sites like windowsupdate and most security-software vendors, you should be OK long enough to get updated.
What's that? You are on DSL or Cable and do NOT have a firewall? Spend a few bucks and get one!
