After I wake my laptop up from sleeping, I encounter really odd functionality. When I click into an application, it appears to rapidly blink, as if you were alt-tabbing out then into it again super fast. When you open a browser and try to type in it, it provides no text - instead it seems to do various other tasks, such as if I were to hit "Y" it would open the YouTube bookmark. If I try and hit minimize/close - it does not allow me to do so. Also if I try and hit the shut down button, it will close all of the applications, that can be shut down (ie avast won't close), in the window's task bar like it normally would, but it never shuts down and I'm left at desktop again. It all seems like a nasty virus, but after I force restart the computer it works as intended.
