You are the man Andre... I had high CPU usage on 3 different PC's and couln't figure out what the cause was. I formatted the first two and the issue went away but I was determinned to find the cause on the 3rd. I came across this forum and your information. I was able to use xperf to find that the driver fslx.sys which is tied to Norton was the cause of my issue. I had a norton/firefox virtual browser installed which I removed and since then the issue has been none existant. Mine was hard to troubleshoot because sometime I could go almost a day without high cpu usage so it took me alomost a week of trying different things to figure this out. I def could not have done it without the info provided here. Thanks
