What are psi.db Error Messages?


General psi.db Runtime Errors

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

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\ProgramData\AVAST Software\Avast\psi.db

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.


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

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your psi.db issue. These troubleshooting steps are listed in the recommended order of execution.

If you are not currently backing up your data, you need to do so immediately.



Download psi.db Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying psi.db to your appropriate Windows system directory. Avast Software typically does not release Avast Internet Security DB files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing psi.db and all other DB files for Avast Internet Security. An incorrectly installed DB file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
