Tdsskiller does one thing. - scan for rootkits. This isn't what you have.
uninstall your non-legit program.
Run a full fledged Antivirus software like avg free, bitdefender free.
Then run malwarebytes anti-malware and update it. Reboot into safe mode and run it.
I would also recommend several programs that can help you to clean your system. I would suggest malwarebytes as popatim suggested. You can also try roguekiller by Adlice, adwcleaner written by xplode, and malwarebytes anti-rootkit. If these do not take care of the problem then you may need a professional.
