Re: How do you secure your PC
If I ran anti-virus: Nod32 or Avast! Home Edition
Truecrypt whole disk encryption
Firefox + adblock plus
Also, a little knowledge about safe computer practices, and I never have problems with virus/spyware/malware. The fact that Gmail doesn't allow exe attachments in emails is also of note.
