An issue has been identified for QuickBooks users who have downloaded an update for the AVG Anti-virus software used. The following error message occurs when trying to open QuickBooks:
An error occurred when QuickBooks tried to start the database server that manages access to the QuickBooks company file. Error (-6094,0)
What You Need To Do
1. Update AVG to the latest virus definition Signature file 271.1.1/2832 (AVG v9.0.814) – this update was just released to correct the issue where AVG unnecessarily detects QuickBooks as infected with a virus.
2. Restore QuickBooks files that were quarantined by the Anti-virus.
