ESET is out of date. Whenever I run an update it fails towards the end.
Sometimes the Update File(s) become corrupted during the download process.
You can try removing all the files from the 'Updfiles' folder in ESET and then try updating again.
The folder is usually located here:-
C:\ProgramData\ESET\ESET Endpoint Security\Updfiles
If you are at all unsure please contact us for support.
Removing the wrong folder/files could cause problems with your PC/Laptop
