How do I know if I have an IRC bot on my computer?
You may not notice the presence of some bots. Others may slow your computer or show symptoms similar to those of spyware and viruses. The CERT-In: Indian Computer Emergency Response Team site explains the functions of an IRC bot in detail and lists a technique to help Windows users locate IRC bots that may be running on their systems. Securityspace.com offers a free malicious IRC bot vulnerability test for registered users (registration is free) at http://www.securityspace.com/smysecure/catid.html?id=14841.
