I use the following:
Norton - AntiVirus and a Spyware Blocker
Spyware Doctor - Spyware Remover
Acronis Privacy Expert Suite
Microsoft AntiSpyware - Spyware Detector
Spyware Blaster - Spyware Deleter (blaster)
Spybot - Search & Destroy
I would recomend you
ALL getting the ones in
bold.
You can find most of them on
www.majorgeeks.com and they are FREE (ones in bold).
I have so many because I go to A LOT of sites on the net. I would say a few hundred + each day searching for stuff.
