If you¡¯re running anything pre-Windows 10 which is connected to the internet you¡¯re really asking for trouble. However, rather than splashing out on a new whizzy machine, many older machines will run a flavour of Linux and be much more responsive than under Windows - and that upgrade is not going to cost you lots of money, perhaps just some time getting up to speed with the new OS.
