I know almost nothing about computers so you'll have to work with me here. I'm not quite sure how I got it but ive noticed my rather expensive computer that should be able to run almost anything with no lag is having trouble even watching a video in windows media player. I checked task manager to see what was wrong and I noticed there are either 2-6 notepad.exe processes running and they all are using 80,000k to 200,000k (not quite sure what that means) and there are also two processes of iexplorer.exe running and those both vary from 200,000k-400,000k. when I end the processes my CPU drops down from upper 80-100% to below 5%. The processes shortly come back within the minute of me ending them. If I try to delete them it says I don't have permission and ive also noticed that it is not allowing me to run antivirus programs or download it. all other internet features work fine but when it comes to downloading or using an antivirus it slows down immensely and often results in error.
