Just this really. And then I have to go to task manager and close it down and open it again but I can't get any work done as I can't save anything. I just installed the windows 8.1 patch two days ago. Any ideas anyone?
Run an antivirus program, perhaps overnight for a full scan, so that your system is clean. If you know you do not have one, use something like Avast! or MSE. Malwarebytes is a great free accompanying tool for an additional scan if you'd like: Malwarebytes : Free Anti-Malware
Make sure your system only has programs that you want installed on it. For example, COUPONTHIS is not a good program to have installed; uninstall it.
The SFC scan will do you good, as well as an antivirus scan, but the rest is just to eventually speed things up, but not really solutions to your current problem. Let me know at least how the scans go, and we'll move on from there.
