Thank you for both of your replies.
Yes, I do click on the 'scan for issues' button first and I have not mistakenly unchecked the issues found.
An acquantaince of mine asked me to right click on the Ccleaner icon and then choose, "Run as Administrator." When I do this a box comes up with "Current user" selected and a check mark in the "Protect my computer and data from unauthorized program activity."
If I then deselect these items and instead select "The following user" my first name is indicated in the drop down arrow box. I am then asked to enter a password but I have no idea of what that password is.
I appreciate your time in responding.
Thank you again.
