I was using windows live mail (which is no longer supported or available.) I used Avast Cleaner and it damaged the program that in such a way that it will no longer open. I get the message that it is damaged or corrupt. If I could go back to a "restore point" of 11/29/2017 the problem would be solved and I could save valuable data in "Calendar" and "contacts" files. It could save years of accumulating data I can't duplicate. Also another problem has happened since the cleaning: My curser jumps backward when I am entering text anywhere in the system (even in writing this memo) or word processing.
