PC Spring Clean - Malware be gone

I had a virus sneak on to my XP machine a few days ago - here are a few good tools to purge Windows of such nasties (use in this order makes sense to me)...

XP's Disk Cleanup
CCleaner
CWShredder
Rogue Remover
Spybot Search & Destroy
Ad-Aware
AVG Anti-Spyware
AVG ant-virus

AVG anti Virus and spybot offer downloads / updates, and stay resident - which are not too bad for freebies.
