Everytime I go on my laptop, during a session I will repeadtly get 2 rundll's in the processes list. I can tell when they appear because the laptop fan will increase speed rapidly. The strange thing is, if I don't end the 2 processes straight away, my CPU usage remains at 100%, the computer will then after about 2 minutes become almost useless. it doesn't crash or close any programs, but everything goes really slow. The mouse will still move fine, and the cursor will change from the loading symbol to the mouse pointer perfectly fine, but whatever programs I have running will become non responsive, and pressing CTRL+SHIFT+ESC won't work, neither will CTRL+ALT+DEL. I've ran both Malwarebytes and Norton 360, but nothing comes up. It's a really annoying thing, and even if i end the rundll proceses, they return anywhere beetween 10-30 minutes later. Any help much appreciated.
