Wow...I had a lot more spyware than that the first time I ever cleaned my comp, but yeah that is pretty bad if that's how much you get regularly. About 2 years ago though, before my comp had a firewall, it slowed down SOOO MUCH it wasn't even funny. When I found out why however, I was surprised my computer was even still running.
After the spyware scanners were run, an antivirus scan, and everything else cleared, the end product was this: 4221 pieces of spyware and 7 viruses.
Since I was introduced to adaware though, I haven't had any problems like that since.
