Is their a "best" malware remover?

You should always use more than one antivirus/malware removal software to be sure you've removed all infections, as some softwares will catch infections that other ones miss. I usually use Malwarebytes and SuperAntiSpyware (as mentioned above, they have a free version available). Also, make sure that your computer's security updates are kept up to date, and that any updates to your antivirus/malware removal software are installed.

The problem with your search results getting redirected sounds like you may have a rootkit infection. If that's the case, you should also run an application called TDSSkiller from Kapersky. It's a tool specifically designed to remove rootkits, since rootkits often aren't picked up by regular antivirus/malware removal software.

I would install and run Malwarebytes and SuperAntiSpyware (you may need to do this in "safe mode", I forget). Then once they've removed any malware, reboot, download and run TDSSkiller, which should get rid of the rootkit, if you have one. Once the rootkit has been removed, run Malwarebytes and SuperAntiSpyware again, to make sure you're clean. Then reboot again and you should be fine. Hope that helps!
