After the scan, the program will ask you to reboot. So restart your PC at once. Do not wait for anything else. Just reboot your PC right away. Using the spyware scanner, do a quick scan of your system after you reboot. If there are still spyware infections, reboot and do another full scan.
I know, I know - it's tedious, isn't it? Well, that's the price we must pay for spyware and adware infection. Just look at it as a viral infection. If we do not kill the viruses in our body with antibiotics, the remaining viruses will become stronger and adapt to the medicine. That's just the way it is when you are on a Windows machine. The best thing you can do is prevent infection in the first place. You really have to watch out for malicious websites and never click on suspicious email attachments.
It's unfortunate that in this day and age spyware and adware are still in fashion. Don't lose all hope because even though it is an arms race, the good guys are almost always on top of the situation.

I think you need to shutdown and restart the program.
