I use Spybot and Zone Alarm, the first time I used Spybot I was also shocked to see how many I had as well, I run the program once a week faithfully
You should get Spy Sweeper, too. I was FLOORED by it.....I found 52!
get Ad-Aware on that pc, too, and run it more than once a week...maybe every other day. Check for updates every time you open it!!!!
don't forget to check for critical updates and clean your cookies and temporary internet files, too.
the original poster might do well to clean everything in TEMP folders, ...
