Well you have a Backdoor Trojan, password stealer on your computer.
These are the most dangerous, and most widespread, type of Trojan.
Backdoor Trojans provide the author or ‘master’ of the Trojan with remote ‘administration’ of victim machines. Unlike legitimate remote administration utilities, they install, launch and run invisibly, without the consent or knowledge of the user. Once installed, backdoor Trojans can be instructed to send, receive, execute and delete files, harvest confidential data from the computer, log activity on the computer and more.
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 them to be compromised.
They should be changed by using a different computer and not the infected one, if not an attacker may get the new passwords and transaction information.
Banking and credit card institutions should be notified of the possible security breech.

Though the Trojans have been identified there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of Trojan, the best course of action would be a reformat and reinstall of the OS.
Should you decide not to follow that advice, we will of course do our best to clean the computer of any infections that we can see but, as I already stated, we can in no way guarantee it to be trustworthy again.
