There are plenty more, but those are 3 of my favorite "free" offline scanners. I prefer offline scanners because then I can load them onto read-only media (CD, floppy) and do an analysis without altering the system too much. Plus, with a web-based scan you have to be on the Internet - sometimes when your client's system is hosed you just can't afford to do that!
Be careful with some versions, as they're for home use only. Don't use them on a job.
One quick word, Trend Micro's Sysclean is easily my favorite freebie scanner. The best is that they really don't list any limitations for it (i.e. for home use only) - so you can use it pretty much anywhere I think.
Do you guys have other offline command-line scanners that you use that are "free"? Post them up!!!
