Are you running Windows 98 or ME? 
As reported here on the Microsoft website, on July 11, 2006, Microsoft will end support for Windows 98, Windows 98 Second Edition, and Windows Millennium Edition, including all security updates.
If you use one of these obsolete operating systems, your computer is quickly becoming a security risk. Without new security patches, older systems are exposed to new security threats, and remain vulnerable for attacks.
Please call your I.T. provider to make sure they upgrade any machines to the latest, more secure and current verrsions of Windows. If you are in Essex, contact AAH Computers, our I.T. sister company, who can carry out these upgrades for you. At the same time we will carry out a security audit on your computer to ensure it is not infected with viruses, malware, trojans or adware.
