A few things you should do...

Open up Add/remove Programs from the control panel and uninstall any garbage that they installed.

Install Windows Defender from Microsoft. This will stop spyware/adware from installing in the future.

If you do not already have antivirus then install AVG antivirus.http://free.grisoft.com/

Windows Defender and AVG are both available at no cost.
