I am running Windows XP, my ram is 1GB, my CPU usage has just now spiked to 100% and seems to stay there. I have just ran a anti spy ware and removed spyware found. But my CPU is still running at 100%. I have noticed in the Windows Task Manager under process running I have approximately many duplicate processes such as devldr.exe. The devldr.exe must have 10 process running and many more items are more than dupicated. When I look under processes the whole area is constantly changing, like it is constantly updating and dupicating itself. What do I have? A virus. I am just running AVG anti virus and nothing appears to be there. Every process takes along time to complete with the high CPU usage. Please advise.
