Windows: Over time, your Windows PC will accumulate a whole bunch of unwanted programs, services and other things that slow it down. FreeFixer sorts and lists everything on your hard drive and offers more information about each to help decide whether it's needed.
Once FreeFixer runs a full scan, it will show you a long list of items including registry startups, scheduled tasks, processes, services, namespace service provides, SVCHost and Explorer modules, and Firefox extensions and search engines. Each item comes with an icon, full file path, and a "more info" link to find out further details about that item. After randomly clicking 15 of them, I'm satisfied with the information FreeFixer is able to give about the items.
To safeguard you from deleting things you shouldn't, FreeFixer does not list critical system files. It further marks files from trusted software publishers (such as Microsoft, Apple, Trend Micro and so on) as "trusted files" in green. These too can't be deleted and they won't appear when you generate a log file. The advantage of this is that when you publish a log file on a forum to identify a problem, it's easier for those helping you.
FeedFixer can be scheduled to run these scans periodically in the background. It also has a File Nuker utility to delete any unwanted file on your next reboot, as well as a Windows System File Checker tool.
If FeedFixer is still a little complex for you, then check out ADWCleaner to remove all toolbars and malware in one click.
