Support for Windows 7 has ended, leaving Marcy wondering how they can protect themselves

I do a lot of work on a Windows 7 desktop PC that is about five years old. I’m a widow and can’t afford to run out and get a new PC at this time, or pay for Windows 10. If I do stay with Windows 7, what should I worry about, and how can I protect myself? I have been running Kaspersky Total Security for several years, which has worked well so far. Marcy
