A dialog box keeps popping up saying lightn~1.SCR has encountered a
problem and needs to close.
When does this message pop up and what system changes (installation/s)
have been made prior to this encounter?
what is this and how do you get rid of it?
I am not running a screen saver
Any screen saver may be started by any program at any time, even when
there is no screen saver selected in the corresponding Windows dialog.
Search your drive/s for the file "lightn*.scr" and check its location
and file properties in order to find out its origin. Note that some
malware comes as *.scr files - check your malware status as well.
