What are Sentry.data Error Messages?

General Sentry.data Runtime Errors

Sentry.data file errors often occur during the startup phase of BullGuard Internet Security, but can also occur while the program is running. These types DATA errors are also known as “runtime errors” because they occur while BullGuard Internet Security is running. Here are some of the most common Sentry.data runtime errors:

• Sentry.data could not be found.
• Sentry.data error.
• Sentry.data failed to load.
• Error loading Sentry.data.
• Failed to register Sentry.data / Cannot register Sentry.data.
• Runtime Error - Sentry.data.
• The file Sentry.data is missing or corrupt.

Most DATA errors are due to missing or corrupt files. Your Sentry.data file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with BullGuard Internet Security), or deleted by a malware infection. Furthermore, Sentry.data file corruption could be caused from a power outage when loading BullGuard Internet Security, system crash while loading or saving Sentry.data, 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.
