Mytob.gen is not a specific worm, but a generic detection for unknown variants of the Mytob family. Worms belonging to this family have the following common characteristics:
- They connect to an IRC server in order to receive remote control commands, such as delete, download and run files.
- Some variants prevent users from accessing certain web pages, mainly belonging to antivirus and security companies.
- They spread via email, across the Internet by exploiting the LSASS vulnerability and across network shared resources that are protected using weak passwords.
If you have a Windows XP/2000 computer, it is highly recommendable to download the security patch for the LSASS vulnerability from the Microsoft website.
Mytob.gen is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
