In this case you will need to obtain an advanced tool which combats trojans, browser hijackers, spyware, etc. GMER is able to wipe these infections by using simple, yet powerful tools. Download the application, run it and perform a scan of the computer. If you see any red items on the scan list, right click them and select Delete, then perform the same scan 2-3 times in a row.
