This is a story of hubris, nemesis and very bad language. Mine. We all like to have our egos flattered and I'm no exception, so when two old acquaintances told me their Windows laptops were infected with viruses I knew they were about to put the bite on me. They did. Could I fix them? Well, my vanity was flattered of course but it was to be a salutary experience that got me to thinking about whether it will ever be possible to wean users off Microsoft products.
