Avg tells me i have this trojan on my system: IRC/BackDoor.SdBot.30.G
However it does not remove it, nor has the A2 scanner found it or The Cleaner Professional. It was restarting my system much the way the Blaster Worm operates, until i blocked all traffic with my firewall. Anyone know how I can remove this bloody thing? Thanks in advance.

I would try using 'Stinger'. You'll find a link to it in the 'Helping yourself' sticky in the Security section of the forum.

I've moved this topic to that section.
