Whilst working on his PC a friend of mine says that the START menu activates on its own and seems to navigate to various programs as if someone has taken over the PC. He says that the programs open randomly and sometimes cause the computer to freeze completely. The problem started a few weeks ago and is getting more frequent. Sometimes he can combat it by pressing the ESCAPE key repeatedly but this only works occasionally. He has scanned the PC for viruses (using McAfee) which reveal nothing. I advised him to do a system restore but he wasn't keen on the idea. He is connected to the Web via an ADSL router.
