Hi


Run a Hijackthis scan and place a tick next to each of the below entries:


R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = res://C:\WINDOWS\system32\tnytp.dll/sp.html#37049
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = res://C:\WINDOWS\system32\tnytp.dll/sp.html#37049
R3 - Default URLSearchHook is missing
O4 - HKLM\..\Run: [UserFaultCheck] %systemroot%\system32\dumprep 0 -u


With all internet explorer windows closed, click on Fix Checked.

Reboot and post back a new hijackthis log.
