Processing speed of my MacBook is extremely slow when opening applications, whether Mail, Safari or MSOffice

Problem description:

The processing speed of any function is extremely slow - such as opening Mail, Safari, clicking on a page within Safari, switching to MS Word, adding a window in Safari, loading a page from Safari. I get the spinning wheel most of the time before the action is completed. All other Macs which are newer in my home WiFi network operate just fine. I have done a top level (novice) check for malware, and haven’t found anything. Any help you can suggest would be truly appreciated! Thank you!
