In the last week I have had troubles with my Laptop. When ever I enter My Documents my computer will start to run at rediculously slow speed. It wont fully freeze but it is still unberable. I looked at my task manager and it said my prossecor was running at 97 - 100%. I have run spy ware and anti spam software. Any ideas or solutions would be great.
