My CPU usage is very high by default. As soon as I starts a program it touches the maximum. After some time it becomes normal. I have a doubt that my disk is infected. So I tried to install MalwareBytes and Kasperkey to scan it. But they consume most of the CPU.
My entire system hangs and I can't scan my system. It restarts some time. Can anybody suggest me a solution for this? And can anybody suggest me a lightweight antivirus suitable for a Pentium 4, 2.4 GHz, 1 GB RAM running Windows XP Service Pack 3?
The problem still persists, here is the print screen of process explorer. It's showing 96-100% cpu usage by interrupts. My machine is crawling because of this. Can anybody give me a solution?
