Summary

The virus installs itself in memory by copying itself into the interrupt vector table at 0000:0200. Virus infects all executed COM files which are between 6 bytes and 60 kilobytes. Virus doesn't reinfect infected files; it determines whether the file in question is infected by searching for KLF starting at offset 3 in the file. Virus preserves file attributes and date/time.

This virus does nothing except for messing up the interrupt table and spreading itself around.

Removal

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.

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 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.
