I have a Dell Dimension desktop PC running with Windows XP - Home + Sophos anti-virus software. Each time I log on to my ISP provider - AOL it keeps dropping out ie signing out automatically - after 30 seconds or a minute. After signing in 6 times or so the it stays signed in. I have done everything that AOL suggest I do to correct the problem still persists. I would be grateful if someone could tell me what the problem might be and how I could cure it?
