What are StartupGuard.cache Error Messages?


General StartupGuard.cache Runtime Errors

StartupGuard.cache file errors often occur during the startup phase of Avira Free Antivirus, but can also occur while the program is running. These types CACHE errors are also known as “runtime errors” because they occur while Avira Free Antivirus is running. Here are some of the most common StartupGuard.cache runtime errors:

Most CACHE errors are due to missing or corrupt files. Your StartupGuard.cache file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Avira Free Antivirus), or deleted by a malware infection. Furthermore, StartupGuard.cache file corruption could be caused from a power outage when loading Avira Free Antivirus, system crash while loading or saving StartupGuard.cache, 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.
