I don't really know if it's Benchmarked or not but I run Advanced Windows Care which does a very good job in keeping my Computer running smooth. And it also get rid of the Freezing and Crashes as well as many other PC problems. And keep Junk Files and Spyware out of your Computer before it even have a chance to Install it self into it. I also use CCleaner. This do a very good job as well though alot of the things it does Advanced Windows Care do alone. One last thing you might want to try is Advance Search Bar. Though it may sounds like something that just search the Web it really help Protect your Computer as well by cleaning up your browse history. I hope this Information was of help.
