    How to prevent Jnf.exe trojan attack

    Recently my computer has been attacked by a Trojan called Jnf.exe. This executable file has infected a variety of tools, similar to regedit, and also won't allow me release Internet or whichever control panel service list otherwise install whichever kind of software in my computer. At whatever moment I attempt to do it, a njf.exe process comes into view on the task manager. I have scanned the whole system by the use of the good and updated antivirus program but it didn’t fix the issue. The antivirus was not capable to remove that Trojan. What can I do now?

    Some of the antivirus program cannot able to clean some infected files or Trojans. As you are saying that it is an executable file. For such file it would be difficult for an antivirus program get into the file and find the Trojan. The Trojan backdoor will be present as hidden file in the system and some backdoors will infect some system related files like Dlls and registry. Such kind of Trojans or virus would be difficult to remove or clean. The only possible way is to permanently block the process using antivirus or firewall program.

    First of all make sure that you have updated the Windows OS and its security essentials. The Windows security essentials takes important role with the combination of Antivirus program to remove the Trojan. The Trojan backdoors infect only those files such which is extremely hard to recognize by the antivirus program. Even if it is detected the antivirus will not delete it because it will cause the system to crash. So if you run the Windows update then the altered files will be fixed automatically and the Trojan will automatically get cleaned.

    There are several free Trojan removal tools available on the internet which you can download to your computer and use it against that Trojan. How can be sure that the infected thing is a Trojan? Run different removal tool and see what would be the results. The Microsoft will offer security patches to its OS when its OS is infected by new Trojan, worm or virus. You should check those first. Otherwise there are several free online virus removal websites available. You can scan through them also.

    If the Trojan has attacked your registry entries then it would be difficult for your or for any program to fix it. First of all try to run a registry cleaner. Sometime it will correct altered registry keys. If this didn't help you then you might need to format and re-install the Windows. If you don't want to format your computer then you should try an alternative method. There is a good online scanning and repair utility called Reimage for Windows which will scan your computer for threats, corrupted files, hardware issues, stability issues and security issues and then it will going to fix online itself if possible.
