What you want is a on-demand scanner that removes already-installed Malware. The most foolproof method would, obviously, be nuking and reinstalling. Assuming this isn't an option though, you can use one or more of several tools specifically targeted towards removing browser hijacks, such as ADWCleaner or Junkware Removal Tool, which has being acquired by Malwarebytes, but should still work. The Chrome Cleanup Tool could work as well.
After that it's a good idea to scan with a normal anti-malware program, such as Malwarebytes Anti-Malware, Spybot Search and Destroy and HitmanPro are good contenders, and they should work alongside normal antivirus fine. HitmanPro uses engines from several other antivirus products and has a 30 day trial if you just want to scan something.
Finally, you can look through the files yourself, by checking some sort of task manager. I use Process Hacker right now, but it has the disadvantage of actually needing to double-click on a process to see DLLs. It's slower work, and you'll only catch the ones that are running, so I'd recommend one or more of the scanners above instead.
