Summary

Since September 5th, there has been information in the media about a trojan called Donald Duck, which is said to spread with a variant of the Love Letter worm. F-Secure is not aware of such a variant of Love Letter. Instead, there has been a hacker attack against an ISP in the Philippines, where the hackers were spreading two known trojans called "donald.exe" and "erap.exe" as email attachments. These files are detected by F-Secure Anti-Virus as SubSeven.backdoor.v213 and Trojan.PSW.Barok.c.

Removal

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.
