Godzilla is a slow mass mailing worm. It activates in a similar way as JS/Kak, by reading an infected email message.
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.
Variant:Godzilla.A
Godzilla.A uses Outlook Express 5.0 to spread as HTML source in each email from infected machine. To do this it saves its code in Update.hta in Windows Startup folder:
C:\WINDOWS\START MENU\PROGRAMS\STARTUP\
so it will be executed next time when the system is restarted.
The virus also saves itself in C:\Windows folder in a file Sign.html. By modifying the Windows registry:
HKCU\Identities\DefaultUserID\Software\Microsoft\OutlookExpress\5.0\Signatures
it changes Outlook Express signature to use Sign.html. On that way the worm code will be embedded in each outgoing email message.
If the date is October 10th, VBS/Godzilla.A shows a message box with a the following text:
Have you danced with the devil in the moonlight ?
VBS/Godzilla.A@m also contains the following comment on the top of its code:
