More details about [email protected]

The [email protected] application is an Internet worm. A worm is a computer program designed to spread across computer networks. It uses a network to send copies of itself to other computers on the network. Worm applications do not infect files but may include one or more threats leading to computer security compromise and information theft. An unsuspecting user typically installs worms by unintentionally opening an e-mail attachment or message that contains executable scripts. Once installed, it replicates itself on the user's system until the time that it does take up all the available memory on the infected computer. This results in system slowdown and may even cause the computer to crash. A worm application may also affect the hard disk. This restricts the user from saving or creating new files.

When [email protected] opens, it terminates all the processes with strings such as firewall, dr. web, spider, kasper, nod32, virus, guard, anti, avp, amon, avg, rav, and avx. [email protected] searches and tries to contaminate all the MSIL executable files on drive C. It also sends itself to all the email addresses that it locates in the Internet Explorer cache folder and Windows address book. The email is encoded at UTF-7 format, and the “from address” is [email protected] The email has VB scripts that add the value “Serotin”. The [email protected] eliminates this registry value after the worm opens for the first time.
