GCHQ has warned people not to do internet banking or use emails from computers with Windows 7 from Tuesday, when Microsoft will end support for the software.
The National Cyber Security Centre (NCSC), the public-facing arm of the cyber spy agency, said that devices still using the operating system after next week will become increasingly vulnerable to cyber attacks as the tech giant stops patching weaknesses in its product.
Microsoft announced last year that it would be ceasing technical support for Windows 7 and urged users to upgrade to its Windows 10 system, which costs £120.
