I am posting some good info (list of free programs) that I got from Roderick. It appears that the worm has hit a lot of people:

I have personally used the 1st on the list of each group with an ADSL connection through aol proxies on a W2k OS - I confirm they work well.

Firewall
Sygate Firewall This product backtraces more nodes than my $60 McAfee!
Zone Alarm A respected program by all accounts but untested by me.

Anti-Virus
AVG Anti-virus by Grisoft
Avast3, Free for home users May have to dig about on the page, but it is free for home use only.

SpyWare Killers (Removes all those naughty little cookies and advertising programs that arrive with so-called free programs.)
Spybot, non-commercial So good I sent him $20
Lavasoft Ad-aware However rumoured to let a few 'selected' cookies remain on the system

Trojan Killer
Swat-It I havent tried this myself, the free links are in the left lower frame area.
I hope you find the links useful.
