Ron hears that he won't be able to use Windows 7 after 2020. Does that mean he can't use his computer? Leo says no. The so-called "end of life" phase, Microsoft won't be updating the operating system with security patches. So he uses it at his own risk online. But if there's something really bad, Microsoft usually puts out a fix. And Leo has a hunch that the 2020 end of life date will be extended.
Leo also says most infections come from out-of-date browsers. So keep the browsers updated. Practice safe online computing. Update the AVS.
And he can always get a cheap Chromebook.
