Hi Prof-rabbit
Win32.Rbot.DUA is an IRC controlled backdoor (or "bot") that can be used to gain unauthorized access to a victim's machine. It can also exhibit worm-like functionality by exploiting weak passwords on administrative shares and by exploiting many different software vulnerabilities, as well as backdoors created by other malware. There are many variants of Rbot, and more are discovered regularly. Rbot is highly configurable, and is being very actively developed, however the core functionality is quite consistent between variants.
IMPORTANT NOTE: Backdoor Trojans are very dangerous because they provide a means of accessing a computer system that bypasses security mechanisms. Remote attackers use backdoor Trojans as part of an exploit to to gain unauthorized access to a computer and take control of it without your knowledge. If your computer was used for online banking or has credit card information on it, all passwords should be changed immediately to include those used for email, eBay and forums. You should consider all your passwords to be compromised. They should be changed by using a different computer and not the infected one. Do not change passwords or do any transactions while using the infected computer because an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breech.
