It's important, however to make suree there's nothing in startup that could revert this situation:
Go to Start/run, and type Msconfig. On the Startup tab, look to see if you can find one or more of the following entries:
SWPortal, SWCaller, Sp.dll, winn32.html, runme.hta, reg.hta, adshow.exe , OPQfile, and/or MSKernel32 (Win32.hta).
If you should find one or more of these, uncheck them.
Also anything that has 'regedit.exe/s' in its path.
Now click OK, close Msconfig, and reboot.
Also have your computer virus scanned.
There are malicious scripts like JS.Exception.Exploit which can do that as well.
