Control-Alt-Delete

I got a Windows update last night. This morning, I got one of those severe warnings along with a handy phone number to call for help in dealing with a virus invasion.  Lynn got one several years ago.  She called the number in the message and we became convinced later that following the helpful advice was what gave baddies access to install trouble.  I think the bill later was $200 to remove the troublesome insertion that helpful sweetie had inserted while "helping" her deal with the problem.  

A more recent difficulty had me carry my laptop to genuine Help.  The young woman who came up to assist lifted the machine, hit a few keys and handed it back.  It was clear that she knew a sequence of keys to use and I asked her what it was.   She told me but I quickly forgot it.  When things went sour today, I searched.  At first, I didn't get anything that helped but with a few adjustments to my search terms, I read to try "Control-Alt-Delete" and that helped a big bunch.  

I don't have the personality to do that sort of work steadily but I am glad I succeeded.  Took maybe a half hour.
