Botter is a dangerous rapidly spreading Internet worm that propagates by e-mail and through IRC online chat network. The parasite arrives in RAR archives containing malicious files.

Once executed, Botter silently installs itself to the system, runs a payload and spreading routine. The worm sends e-mail messages with attached archives containing infected executables to all the contacts in Windows Address Book. It connects to predetermined IRC servers, joins certain channels and sends private messages to other users. These messages contain a link that downloads an infected file from a web server that the worm runs on a compromised computer. Botter can also directly send malicious files to chat users through specific DCC commands.

The parasite's payload is comprised of several harmful functions. Botter searches all fixed, removable and remote drives for RAR archives and inserts a randomly named copy of itself in all archives found. It installs a variant of Spybot worm, which gives the attacker unauthorized remote access to a compromised computer, terminates practically all known antiviruses, firewalls and security-related programs and blocks access to popular security-related web sites and services. Botter also disables certain Windows components.

The worm automatically runs on every Windows startup.
