This virus adds itself to the end of infected files and encrypts the full file after that.
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.
When run, the virus decrypts the original program and writes it to the file called HOOTERS.EXE. Then it executes this file and finally deletes it - sometimes leaving a zero byte HOOTERS.EXE behind.
A side-effect of this is that the memory map might list - for example - an infected mouse driver as HOOTERS.EXE instead of MOUSE.EXE.
Hooters was found in the wild in Australia in September 1996. It has been spread over the internet.
