No matter how well Troj/Agent-XNN can hide from removal, you need to make sure that your system is not infected with this truly dangerous application, which cyber crooks could use for their malignant scams. The backdoor Trojan could easily be used to install more dangerous infections to your computer, and this could seriously compromise your entire system’s coherence. For now, you will have enough trouble having Troj/Agent-XNN removed, as this malicious application is much more deviant than you can imagine.

The Trojan’s running is the responsibility of malignant components file.exe and msiitu.cmd. The dangerous executable is polymorphic and can change its own form, name and location, additionally to being able to circumvent detection and removal tools, hijack the registry, delete disk components, modify runtime policy protocols and steal personal data from the autoexec.bat file. This is how schemers could get a hold of your passwords and usernames, and then breach the security of your own email accounts, copy contact list and use your email address to send mass spam emails with Trojan’s file attachments to infect other computers. This is also the component that hides the existence of msiitu.cmd or New_Photo_with_your_friend_on_Facebook.jpeg.exe. As you could have already guessed by the name of this file, it is linked with Facebook and social engineering scams, another way for cyber criminals to breach your system’s security obstacles and infect the computer.

If you are used to getting email alerts about Facebook activity, you might not be surprised to find out a message with a notification about new online photos of a friend. For example, you could find an email sent from the fictitious domain with a subject line “Your friend added a new photo with you to the album” and the text would say:

Greetings, One of Your Friends added a new photo with you to the album. You are receiving this email because you've been listed as a close friend. View photo with you in the attachment.

Of course, if you click on the attachment or download it, you would simply be allowing Troj/Agent-XNN into your computer; therefore, it is strongly recommended being wise whilst on the Internet. Social engineering and black hat SEO scams are very common malware propagation channels, and this complement such infamous tricks and bundled or encrypted downloads, malvertisement, infected removable drives, etc. What is more, you should also be smart when trusting seemingly legitimate websites and companies, as any schemers could easily incorporate, for example, Facebook name to trick you into thinking that you can trust, in reality, malignant source.

Since the Trojan is truly treacherous and dangerous, it would be best to remove it using such legal security tools as SpyHunter, which could securely protect your personal data in the long run. If you want to delete Troj/Agent-XNN manually, make sure you understand the risk behind this complex removal task and if you still want to continue, delete all registry keys and files listed below.
