mod.ver file errors often occur during the startup phase of ESET Nod32 Antivirus, but can also occur while the program is running. These types VER errors are also known as “runtime errors” because they occur while ESET Nod32 Antivirus is running. Here are some of the most common mod.ver runtime errors:

Furthermore, mod.ver file corruption could be caused from a power outage when loading ESET Nod32 Antivirus, system crash while loading or saving mod.ver, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.
