It will not let me clear my history. If I hit the button it freezes. Basically the hourglass justs keeps spinning. If I go into the task manager is says it's not responding. I usually clear my history each day. This started happening on Friday. Also I noticed last night that on my desktop if the computer is just sitting idle with no programs open there seems to be something running in the background or I am guessing that. My pointer turns into the hourglass every couple of seconds. I ran a virus check, nothing. Please help.
