Download: CCleaner (freeware)

Run the installer, and uncheck the option to install Yahoo toolbar (unless you want Yahoo toolbar of course)!!.

Once installed, run CCleaner click the Windows [tab]

The following should be selected by default, if not, please select:

Next: click Options click the Settings tab

Uncheck: "Only delete files older than 48 hrs.", click Ok

Then click Run Cleaner (bottom right) then Exit

Download and run spybot or AVG antispyware.

Finally

Go to Start->Control Panel->System, Click on the System restore tab. Tick "Turn off System Restore" and then reboot your computer.

That will erase all restore points.

After reboot, go back in again as above, and Turn System Restore back on. <<< IMPORTANT!!
