Have you tried using TDSSKiller? It only looks for specific things, but in my experience those are usually what caused me to redirect. I'm looking at an old version, so I don't know if anything's changed, but I have the additional options off because it gives false positives. Service and Drivers and Boot Options should be enough.

I've also used Malwarebytes Anti Malware to scan for problems. I haven't updated this one in a while either, but a quick scan might be enough. Full scan to be safe. Definitely use both of these in Safe Mode.

They're both free (although I think Malwarebytes has extras if you pay; I've never paid), and usually they work pretty well together for me. I've had some stuff slip through and mess up the computer, though. You definitely want to address a redirect virus as soon as possible; it might have been coincidence, but after weeks of struggling with a redirect I encountered another virus that, as far as I could tell, corrupted the operating system to the point that I couldn't even do a factory reset.

No, I don't know if that's exactly what happened. But I could only access my files by burning a free OS on a disk and booting from that, so it's not as if it simply deleted everything, but it definitely wrecked some essential system files. I had to buy a whole new computer because of it, so I'm hoping that things will be better for you. Good luck!
