Thank you.

I selected scan at boot and following terminating at 23% using the esc key windows 10 flagged that it was not activated.  Renetering the code appears to have fixed that.  there were a number of .cab and .exe files marked as corrupt and a .dmp file was quarantined.  Normal scan had not reported any problems.

Has anyone else seen this?
