These days, there are tons of free “Cleanup Programs”. How do you know which ones are real and which ones really work? That is tough because we have tested various ones that you see offered on TV, such as finallyfast.com and others. We have found that majority of these registry and system cleaners can do more harm then they do help. Some such as finallyfast.com have even been found to have spyware built into them. The only one I have found to work well is CCleaner. This is a great program and will clean your computer pretty quick. So when surfing the web for a free alternative, be careful, because you might just make your PC worse than it was before or compromise your PC to more spyware and viruses.
