It degrades your computer running speed and brings many other nasty infections into the computer. Moreover, this Trojan horse will try to collect your personal information by monitoring your activities. You need to get rid of it immediately without delay. Users can follow the manual guide here to remove the virus efficiently and completely.

1. Know Your Enemy
Any great war general will tell you to know your enemy, get inside their head, think like they do, act like they do, and become their best friend, as this will prepare you to overcome your enemy. So engage with the virus: keep an eye out for any security messages that pop up, as these usually provide the exact name of the virus that has infected your computer. If it gives you a security message that says "For More Info Click Here," or something else to click on, and it is not asking you to enter personal financial information or install anything, you may want to go ahead and click on it. Be prepared to write down any product name it gives you, or any file name and directory path (example: C:\Users\YourUserName\AppData\LocalLow\Temp\Virus). Remember, NEVER give out your personal financial information in these dialogues with malware.
Now if you were lucky enough to catch a security message and get the name of the virus itself, then you can continue on to Threat Expert and get all the information you can on that malicious software.
If you were only able to get a product name, then you need to do a search on it. Most likely, you’ll find out that the product is "fakeware" (malicious software that calls itself an anti-virus program).
In your search, it's a good idea to pursue results that link you to a forum, as you may find the information you need in discussions there, for example the name of the virus infecting your computer.
Once you have the name of the virus and the report from Threat Expert you can begin the hunt. It won't be a long hunt if you were able to get the directory from the "security" message, because that is where that little malicious bugger is hiding.
2. Block the Virus from the Startup List
You can’t kill the virus unless you put it to sleep first. So to put the virus to sleep we will end all the processes created by the virus.
A first step is to block the malicious program from starting itself up along with your usual programs every time your computer starts up. You can use System Configuration ("msconfig") to do this. One way to do this is to click the “Start” button on your desktop, type "System Configuration" into the "Search" field, and select “Start System Configuration” from the results. Or find it by clicking "Start," then "Control Panel," then "System and Security," and then "Administrative Tools," and then double-clicking "System Configuration.?"
System Configuration is great for helping with virus removal, allowing you to keep the virus turned off when you start up again.
System Configuration opens the "General" tab, where you will need to select the circle next to "Selective Startup." Next, move to the “Startup” tab and go through the list there: select all the programs that have an unknown manufacturer and disable them, because programs with unknown manufacturers are almost always malware. Restart your computer to close any currently-running versions of the malware.
3. Start Task Manager and End Virus-Related Processes
When your computer restarts you will open your Task Manager immediately, which can be done quickest by pressing the "Ctrl," "Alt," and "Delete" keys all at the same time and then selecting "Start Task Manager" from the options that appear. Select the “Processes” tab and then compare the processes listed as running on your computer to the list of virus-created processes you got from the Threat Expert report or other research. Any processes running on your computer that match the ones on the report need to be ended, until all virus-created processes are gone.
4. Seek and Destroy That Malicious Software: Delete Its Files
Now we will go to the directory where the virus is and delete the virus. Tip: viruses like to hide themselves inside your “Temp” folder. If you got the directory path from the security message the virus gave you, then all you need to do is open up your computer's Explorer window and follow the path. For example, if you were looking for "C:\Users\YourUserName\AppData\LocalLow\Temp\Virus…" you would click on the "C" icon in Explorer, for the computer's hard drive, then click the “Users” folder, then click the “YourUserName” folder, and so on, until you get to the virus. Now delete any file names that match those on the virus report.
5. Seek and Destroy Some More: Remove Registry Keys
Finally, we will go into the Registry and remove the registry keys the virus put in. To go into the Registry, click the “Start” button on your desktop, click “Run,” type "regedit," and click "OK." Or type "regedit" in the search bar on your Start Menu, and select the Regedit program from your search results. You can find the exact name and directory path of the registry keys created by the virus from the Threat Expert virus report. Delete the registry keys that the virus created--do be careful to delete the exact keys you have in mind, no others--and you should be virus-free.

Note: Of course, it's highly recommended that you should remove trojan horse in a professional way if there are still some similar problems with your computer.
