Cervivec is a mass-mailer worm written in Delphi. The code body is over 600 kilobytes in size. It collects email addresses from the user's ICQ contact database.
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.
The worm installs itself to the Windows System directory as "ntkrnl.exe" and adds a value to the registry to
"Software\Microsoft\Windows\CurrentVersion\Run\Kernel Loader"
to make sure that it will be started when the machine starts up.
It sends email messages in different languages:
"Cau posilam ti cerviky tak se na to podivej (virus to neni)" "Cau posielam ti cerviky tak sa na to pozri (virus to neni)" "Hallo, Ich habe ein guter Witz-Wurm so sieh! (kein virus)" "Hi, I have some cool joke - worms so have a look at it (no virus)" "J'ai une bonne blague ca s'appelle verre de terre alors jette un coup d'oeil (il n'y a pas de virusi)" "Czesc, mam swietnz dowci te mando los gusanilloes. Pues mirarlos (no es un virus)" "Hola te mando los gusanilloes. Puesmirarlos (no es un virus)"
