been there done that it was a pain in the ass

1. Use Malware bytes and spybot and scan and remove anything it finds
2. Open Programs and Features in control panel and remove any programs you don't recognize, there could be 3 or 4 in there
3. Find your shortcuts to your web browsers (you will need to do each one you have), right click, properties, then in the target make sure its just something like this "C:\Program Files\Internet Explorer\iexplore.exe" with nothing after it, there will be a redirect link after it so every time its opened it will take you there.
4. change your home page back to your default

That should take care of it all
