An Access 2000 database may stop responding when you open the database in a multi-user environment

“This article applies only to a Microsoft Access database (.mdb).
Moderate: Requires basic macro, coding, and interoperability skills.
SYMPTOMS
When you open an Access 2000 database in a multi-user environment and then you run Trend Micro antivirus software on your computer, the Access database may stop responding. If you use Windows Task Manager to try to end the task that corresponds to the database, you may receive the following error message:
This program cannot be closed. If it is being debugged, please resume it or close the debugger first.
CAUSE
The Trend Micro scan engine software scans all the types of files in the scan list. The scan engine of the antivirus software may take longer to scan large Microsoft Access database files (.mdb) than other types of files. If you try to close the Access database file while the file is being scanned, you may receive the error message that is mentioned in the ‘Symptoms’ section.
RESOLUTION
To resolve this problem, remove the .mdb files from the scan extension list or remove the .mdb files from the Trend Micro Scan Engine software virus scan.”
