Win Fixer is a piece of malware which pretends to be a diagnostic tool. The makers of Win Fixer claim “WinFixer 2006 detects and repairs corrupted files, removes useless data, cleans up clogged Windows registry and fixes hard drive errors. This useful utility helps you maintain an error-free PC and achieve 100% system performance.”

Win Fixer is distributed as a part of many software packages. It then executes every time Microsoft Windows starts up. Win Fixer will assail you with adware messages about illusory problems with your PC.
