no, there are many backdoor trojans and do not know all of them, i have a good antivirus and firewall which takes care of frontdoor and backdoor torjans,
What's the different how they're called. I think you should download Bitdefender (or Kaspersky, Norton) and everything scan with it, after few seconds program should find your trojans and delete them of course...
Sorry i haven't heard that, but i think is more easy by instaling+updating+scan your computer with the Antivirus !!!
Let the antivirus work, and see ...
