Technical Details



Various F-Secure Anti-Virus products detect newly created e-mail-based malware usingZero Hour Protection only moments after they begin spreading. Typically these viruses and worms have not yet been analyzed; it is the Zero Hour Protection techniques that confirm the inspected e-mail contains new malware.

At this stage of detection, the malware has not yet been included to the more traditional virus definition databases. It does not yet have a signature. As soon as the detection has been added to the definition updates, the name will be changed from the generic Email.0Day.Malware to the actual name of the malware. If the e-mail messages infected with Email.0Day.Malware are rescanned at a later date the infection will likely have a different name.

Every new malware detected by F-Secure Anti-Virus products utilizing Zero Hour Protection use the generic name of Email.0Day.Malware. Multiple viruses or worms are detected under this name.

If at all possible, please provide a sample of the malware detected for analysis by our Security Labs. This will assist us in creating signature definitions to include in our detection databases.
