What’s 0.dat? Is it safe or a virus?

Who dat? 0.dat? What a suspicious name for a file. In fact, while researching this executable I found many posts from Nvidia hardware owners (in the Nvidia forums) saying this file had been falsely flagged as malware by their antivirus program. So what exactly is this suspiciously named file (0.dat) and why is it running in the Windows Task Manager?

After some research I found that 0.dat (not related to O.dat) is typically a part of the driver packages for Nvidia graphics cards, containing important configurations and settings. For example, this process may start running if Nvidia releases a software update. 0.dat may also contain firmware updates and other essential data Nvidia hardware.

In the Nvidia forums, some different people claimed that this file is somehow related to different PC games, and helping them run in a more stable way with Nvidia hardware, but I couldn't verify that...

After checking the different PCs with Nvidia hardware in our SpyShelter cybersecurity lab, we found that any PCs with Nvidia did in fact have 0.dat. Therefore, we believe that as long as this process is signed by Nvidia, then it should be safe to run on your PC.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
