I have tried out SO many security applications. And I actually have liked most of them. But almost all of them seem to suffer from one problem: they slow down my machine. I actually liked all of the following applications but uninstalled due to resource usage: ewido, Spysweeper, and Counterspy. Online Armor...I like this one too but it conflicted with my firewall, causing a slowdown. Spyware Doctor...I liked this program more than all others but it gets too many false positives. Anyway, NOD32 does it right. Same with Spyware Terminator. These products seem to protect well, but don't slow down my machine. What others?
