Okay, Looks like you have Trojan.Sirefef.C, which is a backdoor Trojan.
Trojan:Win32/Sirefef.C is the detection for a component of the
Win32/Sirefef family- a multi-component family of
malware that moderates your Internet experience by changing search results and generating pay-per-click advertising revenue for its controllers. The family consists of multiple parts that perform different functions, such as downloading updates and additional components, hiding existing components, or performing a payload.
]
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.

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!

Please download
AdwCleaner by Xplode and save to your Desktop.
Step 1.
- Double click on AdwCleaner.exe to run the tool.
Vista/Windows 7/8 users right-click and select Run As Administrator.
- Click on the Scan button.
- AdwCleaner will begin...be patient as the scan may take some time to complete.
- After the scan has finished, click on the Report button...a logfile (AdwCleaner[R#].txt) will open in Notepad for review (where the largest value of # represents the most recent report).
- The contents of the log file may be confusing. Unless you see a program name that you know should not be removed, don't worry about it. If you see an entry you want to keep, let me know about it.
- Copy and paste the contents of that logfile in your next reply.
- A copy of all logfiles are saved in the C:\AdwCleaner folder which was created when running the tool.
Step 2.
Using AdwCleaner v3: Scan & Clean:
This time click on the Clean button.
Press OK when asked to close all programs and follow the onscreen prompts.
Press OK again to allow AdwCleaner to restart the computer and complete the removal process.
After rebooting, a logfile report (AdwCleaner[S#].txt) will open automatically (where the largest value of # represents the most recent report).
Copy and paste the contents of that logfile in your next reply.
A copy of that logfile will also be saved in the C:\AdwCleaner folder
