1: Secunia Personal Software Inspector: ok.
2: OpenDNS: give up, server down from time to time to me.
3: Active Virus Shield (free anti-virus): incompatible with avast. Never tested.
4: Haute Secure: new to me. Need to learn about it.
5: GMER anti-rootkit: too advanced for my knowledge. I only use if someone else analyze the results.
6: Netcraft Toolbar: tried in the past, by Polonus' advice. Give up.
7: File Shredder: I use Eraser.
8: CCleaner: ok.
9: PC Decrapifier: ok.
10: NoScript for Firefox: must have.
Thanks Bob.
