• If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.

Uninstall Spybot and Super AntiSpyware. Spyware programs are not that easily available, if you use the internet using the sense .... those may come form some selected places, avoiding them is enough. Use a real time protector, that you dont have at all. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.
