Dll file is not working. file is not responding.
Hello Roy. What is your OS and its version? What is the Norton product you are using and its version? What program is this file related to and what notices, if any, are you getting? DLL files are shared libraries, some of which are system files. Given the file you referenced is numeric I would suggest a possible system infection. Download and run a full scan with Malwarebytes, select use the FREE version vice the 14 day trial. Let us know your results.
Cheers
