The thing that I have used which is not currently listed, is Spyware Blaster from JavaCoolSoftware;
SpywareBlaster® | Prevent spyware and malware. Free download.
Rather than scanning and finding a problem "after the fact", spyware blaster makes a few changes to prevent the problem from happening. It doesn't run in the background as a process and consume resources. Instead, you open the app, update it, tell it to fix known issues for your currently installed web browsers, it makes it's changes...and it's done when you close it.
I'll be honest, I rarely ever run into any type of problem. So, I cannot say that this program is super effective, but I can also say that it hasn't caused me any problems either. Perhaps it's things like this which keep me safe in the first place, and I simply don't know it.
Note: It protects IE, and it protects Firefox....but Chrome is not in the list of protected browsers. So, if you are mostly a Chrome user...this may provide very little benefit to you.
