Doenload and install Malwarebytes. Run a full sweep of your system, and review the results. You should be able to remove the majority of the infections, but some may need further tools to sort them out once identified by Malwarebytes.

I also recommend spybot search and destroy
Assuming your on windows, you can also perform a system restore to when you didn't have any spywares/trojans.
