Go to start, then Control Panel, then programs and features. Uninstall anything related to Surf Canyon. Anything that looks suspicious. Besides, don't know which browser is infected, so I would take Firefox for example. After doing all that above, Reset Firefox. Firefox reset is the easiest and best way to fix nearly all problems in Firefox: Go to Firefox > Help > Troubleshooting Information>Click the “Reset Firefox” button. When this is done, you can remove Surf Canyon from your browser surely!
