You can find Revo Uninstaller at http://www.revouninstaller.com (freeware). Heres a quick look at how to use Revo uninstaller.
Launch Revo uninstaller after installing, select the program you want to uninstall or search for it using the built in search tool.
Click the Uninstall button on the toolbar
This will start the uninstallation wizard for the particular program you selected. Revo uninstaller will go through a series of steps which include creating a system restore point, creating a backup of your Windows registry.
Then analyze the program and run its default uninstaller, click Yes when you see the above dialog. After the uninstall is completed, you have a choice of scanning modes to select from. What this will do is let you scan for any left over files, folders and registry
items from that particular program. Safe looks in the usual places, moderate in more advanced locations while Advanced does a thorough search throughout the entire computer. After selecting your choice, (I went with Advanced), click Scan.
After the scan is complete, you will see a list of registry entries left behind by the program, select them then click Finish to thoroughly remove the program from your system.
The default uninstaller should work for most persons, but for those troublesome programs, the Force Uninstall feature and advanced scanning options will give you more control.
If you continue to experience problems removing the software, you might need to scan your computer for malicious code.
