re: #312 Locker
Additionally get Spyware Blaster and install/update it. That program isn’t a scanner, it’s a passive blocker but it blocks a LOT of shit.
Just to make sure you and others get the right links:
Security
Spybot
ad-aware
spyware blaster
avg free
zonealarm free firewall
Utilites
EasyCleaner
keepass - password safe
