Summary

This virus was written by two brothers in Switzerland, 18 and 21 years old. The virus is related to the 'Flip' virus - possibly they wrote it as well. Tequila is difficult to detect as is uses a variable encryption algorithm. When an infected program is run, the virus will infect the MBR of the hard disk, so the next time the computer is booted, the virus will be active in memory, ready to infect .EXE files as they are run. One interesting effect of the virus is the display of a crude, character-based Mandelbrot set image on the screen.

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.
