Yesterday 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. My computer has also become less responsive, briefly freezing every so often and not always registering when I click on something. I know WAT is a legitimate program from Microsoft, but I was on an untrustworthy site when it first started happening and I suspect something malicious got onto my computer and is trying to use the program to negatively affect my system. 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.
