Virus, Trojan




A97M is F-Secure's platform designation for malware spread in specially crafted Microsoft Office Access documents (version Word 97 and onwards).

Automatic action

Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

Vulnerability Protection

The vulnerability (or vulnerabilities) leveraged by the specially crafted document file are usually application- or platform-specific; a particular program (or even a specific version of the program) must be installed on the machine in order for the exploit to be effective.

To prevent exploitation of such vulnerabilities, please refer to the application vendor for the latest updates and additional advice.

Suspect a file is incorrectly detected (a False Positive)?

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest detection database updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note You need administrative rights to change the settings.

Technical Details

Due to the almost ubiquitous nature of the Microsoft Office business suite, specially crafted document files are often used as a vector for delivering malware. Such documents typically exploit a vulnerability in the document management program itself in order to plant the malware on targeted systems.

Specially crafted Access documents typically contain malicious code that silently executes when the document is opened. The malicious code is usually inserted as macro code. A representative example of A97M malware is:
