2. Do not check or use any outside e-mail services from your laptop or desktop computer. This includes hotmail, yahoo mail, AOL, e-mail accounts you might have with your local ISP etc. For laptop users this applies to you whether you are using your laptop here in the office or from home. I know this is a hardship, but so is chasing down and removing viruses from our network.
Sure. I'll put that right on the top of my action agenda.
