My computer is roughly 3 1/2 years old now but this past week it has slowed down tremendously. It recently got new memory and it was speedy after that plus I recently had a virus so it has been completely cleaned out pretty much. But in the last week I have downloaded: last.fm Windows live 8 and some photoshop actions, and music files. I mean i just waited 7 seconds to get my bar thing up that has all my window open.(i forget what its called) And there is a de.ay on what I type. I have restarted many times with no success. It's gotten to the point where I can't talk to people on my messenger or go to certain websites but I am pretty sure it's not a virus. I'm not getting any messages saying anything is malfunctioning and my virus scans are coming up clean. So.. help please?
