From Comvigo:

IM Lock is a powerful Instant Message Blocking software for home, education, and small business. IM Lock was created to protect internet users from the new dangers posed by instant messaging (IM). Instant messaging has become the new access vehicle of choice for hackers, worm virus writers, identify thieves, online predators, and cyber stalkers. IM Lock is specifically designed to prevent these threats at homes or organizations that have 1 to 50 computers. Beyond virus protection, IM Lock provides other important benefits.
