I run bitdefender scan but nothing found
what is that file ?
it is on the root of my WD drive
can I delete it ?

msdia80.dll is present on your D: drive because you installed games on that drive. That particular .dll comes from Visual C++ 2005 Redistributable Package which some games will install because it is required to run those particular games. I would advise AGAINST deleting it, as deleting that file may make some of your games unplayable. ax64 time machine did not create the file.
