Memscan:trojan, Memscan:rootkit, Memscan:worm, Memscan:virus


This detection indicates that the program or file performed suspicious or harmful actions when it was run in an isolated virtual environment.

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.

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

Suspicious or harmful behavior in a sandbox

To examine a program or file's actions more closely, the security product will run it in an isolated, tightly controlled virtual environment that mimics a normal computer system (a sandbox). The program or file's actions within the sandbox are monitored, and if it performs suspicious or harmful actions, it will trigger a detection.

The detection 'Memscan:[variable]' (where [variable] can be 'trojan', 'worm', 'virus' or similar) indicates that suspicious processes or components were found in the sandbox's virtual memory after the program or file was run.
