The best occasionally run anti-spyware is Ad-Aware SE, also free, click on Ad-Aware @ Lavasoft - The Original Anti-Spyware Company - Lavasoft & download Ad-Aware free. I recently ran this on a friend's machine who had never had anti-virus, anti-spyware or a firewall & he had 15 Trojans & 290 other viruses including 200 instances of Sasser Worm.
It is a pretty awful thing to do to a partner I'd be furious.
Before people get too panicky and think that every bit of spyware means their nearest and dearest are spying on them, I don't really consider pc pandora to be the average spyware program that goes on your computer.
PC pandora is legit and I know parents sometimes use it to track what their children are getting up to.
Spyware can really mess up your computer with pop ups etc and send data back, pc pandora is a little different.
