I also just received a call from Quickbooks Support Team.  Unfortunately, he seemed legit after asking him some pertinent questions.  

He also said it was about some downloads that were not being installed and he advised me to go to Help>Update Quickbook Desktop and update the files.  Some files were not being downloaded and some errors were present.  He had me reset the update and try that and some files downloaded but one did not and there were two errors.  He asked me to download Logmein123 and set up remote control for him.  Unfortunately, I did this.

The conversation and trials went on for anothe 20 minutes and finally he said I needed another service that he downloaded which I could purchase for $399 dollars.  That's when I got suspicious and ended the conversation and he warned that Quickbooks could not guarantee that problems would not  happen to my software if I did not buy this extra service.

Now I'm not sure I'm even talking to the real Inuit support online.   I have changed the password for my Admin.  Anything else I should do?
