Those who want to keep a Pc clean of Malware might want to download and use these freewares:
Spybot Search & Destroy
EMCO Malware Destroyer
SUPERAntiSpyware FREE Edition
I also used to use AdAware, but no more as I have had trouble with it, other than AdAware, all of the other above programs can be intalled and used as they don't get in the way of each other, they are compatible and each of them complement each other, just only run one of them at a time, when you finish with one then you can run any other one, one at a time, when all have been run, there should not be any Malware left on your Pc maybe, or very little if anything, update them before each use and try to use them at least once a Month, or whenever you have malware problems, or after you download programs so they can be checked for viruses and malwares.
If nothing else, at least use ClamWin and SpyWare Terminator and a good FireWall, not the Windows FireWall, but a better one, of course first disable the Windows Firewall before you use some other one.
You can find them with Google or with any other search engine.
I use all of those myself, one at a time of course, don't run two of them at the same time, run one and then later another one and so on untill all of them have been used, then you will have a malware clean Pc.
For Viruses use AntiVirus software such as ClamWin and SpyWare Terminator, they are also freewares.
