This afternoon my computer started asking whether I wanted to allow Windows Activation Technologies to make changes to my computer. I keep clicking "No," but it pops up again every thirty seconds to two minutes later. I looked it up and it's apparently an anti-piracy software that prevents an illegitimate copy of Windows from running after 30 days or so, but I've had my legitimate computer for about two-and-a-half years now. I suspect a virus or whatever is trying to use it to maliciously affect my system. My computer has also become less responsive, briefly freezing every so often and not always registering when I click on something. I'm using Windows 7 Home Premium with a 64-bit operating system on a Lenovo laptop. The program that keeps requesting permission is located at C:\Windows\system32\Wat\WatAdminSvc.exe . There's probably a lot more information you need--I've seen posts with huge logs of data--so please let me know what info you need and how to get it for you.
