Summary

The only unusual feature of this virus is that it does not store the original partition sector anywhere - instead it just overwrites the first part of it, and performs its functions.

The virus may cause some strange symptoms and interfere with printer operations, as after 32 boots, the virus activates and disables the system's COM1 and LPT1 ports.

When Azusa infects a floppy, it overwrites the sector at Track 39, Head 1, Sector 8. This is at the end of a 360 Kb floppy. However, it is in the middle of a high-capacity floppy, thus almost certainly destroying information there.

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.
