Remove Crutle.b. Description and removal instructions

Title: Crutle.b
Type: Worms	Severity scale: (50 / 100)

Crutle.b is a worm that spreads via IRC chats and through file sharing networks using popular Kazaa software. Once executed, the parasite silently installs itself to the system and creates a folder with numerous infected files inside it. These files have meaningful names. Then Crutle.b shares a new folder using the Kazaa program, making files inside this directory accessible to other peer-to-peer clients. The worm doesn't carry any destructive payload, as it is designed only to spread. Crutle.b automatically runs on every Windows startup.
