My first post, so apologize in advance if not following correct protocols. Running Windows 7 on an HP p6774y desktop. Primarily use Firefox for a browser. At startup tonight, lots of hard drive access, which seems to happen from time to time. Opened Task Manager just in time to see a process dirt.exe, with very high PID count, bounce around the top couple of processes then disappear. Quick Google search was not encouraging so thought I would inquire on the Norton forum for any insight. Any help appreciated!
