Bagz Removal Tool is a small but powerful utility that was created in order to provide you with a simple means of erasing the Bagz.B@mm malware.
This is a mass-mailer that also drops a backdoor. It also tries to disable the windows firewall and to install it's own network driver in order to avoid detection by normal firewalls.
The worm starts a thread that searches for mail addresses every 2 hours in files of types:
.txt
.htm
.dbx
.tbi
.tbb
It sends mail using it's own SMTP engine (it parses the mail address and then uses a DNS query to connect directly to the recipient's SMTP server).
