The term Trojan horse comes from the ancient Greek mythology. During the siege of Troy many unsuccessful attempts were made to breach the city’s defenses. Finally a large wooden horse filled with Greek soldiers was devised to lure the Trojan soldiers to open the gates and bring the horse inside. Once inside and at the right time when the defenders’ attention was elsewhere the soldiers inside the horse popped out and conquered Troy.

The virus application uses the same type of methods to misguide your computer defenses and infiltrate your system. Once there it might remain dormant for a long time until the appropriate conditions for its activation are met.

So that’s what a Trojan does:

One of the scariest things about having a Trojan virus is that if the application manages to gain privileged access to your system by virtue of you providing it, then it practically would have a free reign upon what mischief to bring upon your computer, entirely dependent on what the creators of the virus want to do. As you can imagine none of the possibilities are enticing or harmless.

Some of them include:

  • Crashing or breaking down your device entirely.
  • Remote alteration or even full deletion of certain or all files on your hard drive.
  • Alternatively the corruption of selected data files.
  • If you are in a home or work network your computer might be used for malicious software spreading.
  • Spying on your computer or if you are in a network spying on computers in your network using your computer as the instigator.
  • Even a complete remote hard drive wipe-down is possible.

Another possible and debatably worse possibility is if the creators of Trojan:Win64/!dll Virus choose to use your computer’s resources for shady and sometimes downright criminal activities like:

  • Your device being used as a “bot-net”, or a spamming source in essence.
  • The use of your hardware for bitcoin and other “coin” mining which is not only irritating but can also significantly speed the wearing down of your hardware, not to mention the crazy electric energy bills.
  • As we mentioned previously the use of your machine for malware spreading is quite possible, even likely.
  • Your computer being used as a “proxy” of sorts to launch cyber attacks and other illegal activities that fall under the penal code.

Of course there remain the issues that are manifesting themselves via the help of a Trojan horse virus – online identity theft and ransomware applications. Identity theft is a very serious crime and as you probably know the implications can be very damaging for you personally. Our advice is to never take this type of threat lightly. Maybe you are less familiar with Ransomware software and what exactly is does. Basically if you have the displeasure of waking up and finding your files encrypted and you being unable to access them, they you know you have a ransomware virus on your computer. It is called ransomware because a certain amount of money is demanded as a sort of “ransom” to get the decryption key required to “unlock” your files.

Remove Trojan:Win64/!dll Virus


Reboot in Safe Mode (use this guide if you don’t know how to do it).

This is the first preparation.


To remove parasite, you may have to meddle with system files and registries. Making a mistake and deleting the wrong thing may damage your system.
Avoid this by using SpyHunter - a professional Parasite removal tool.

Keep in mind, SpyHunter’s malware detection tool is free. To remove the infection, you'll need to purchase its full version. More information about SpyHunter and steps to uninstall.

The first thing you absolutely must do is Reveal All Hidden Files and Folders.

  • Do not skip this. Trojan:Win64/!dll Virus may have hidden some of its files and you need to see them.

Hold together the Start Key and R. Type appwiz.cpl –> OK.


In Safe Mode (if you skipped the previous step, go back and do it) type cmd in the Search Field. Righ Click it —> Run as Administrator. In the new window, type sfc /scannow and press Enter. Wait for the verification process to finish. You should get the following message:

DNSAPI dll removal

At this point, you successfully removed the DNSAPI.dll missing error.

Hold the Start Key and R copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Open the Start Menu, type “Control Panel” in the search box —> Enter. Network and Internet —> Network and Sharing Center —> Change Adapter Settings. Right-click your Internet connection —> Properties.

In Networking, left click Internet Protocol Version 4 —> Properties. If everything is normal, your window will look like this:

DNS Settings

If it’s not, click on the two “automatic” choices. NOTE: If you are in a domain network, contact your Domain Administrator so he can make these settings, or this may break your Internet Connection.


Right click on the Taskbar —> “Start Task Manager.”


Go to the Processes Tab. Try to determine which ones are a virus. Google them or ask us in the comments.


Dear reader, since you will need to manually manipulate and alter files and processes that are essential for the normal functioning of your operating system, it is very important to proceed with a maximum level of cautiousness. You need to be aware of the fact that even a seemingly innocuous mistake might have pretty significant and often times irreversible consequences for your device’s health. You should only continue if you are feeling confident in both our instructions and your own ability to follow them to the dot. If you have any doubts or do not feel like taking chances we always urge our readers to consider alternative methods for malware removal.

One such method is to download and installation of a professional software to scan your hard drive(s) and fix your issues in a completely automated and safe procedure.


Right click on each of the virus processes and select Open File Location, then End the process. Copy the folders somewhere (as a backup if you make a mistake) and delete the directories you were sent to.


Type msconfig in the search field and hit enter. A window will pop-up:


Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random


If these things fail to help you find Trojan:Win64/!dll Virus you need to resort to a professional scanner – obviously this is a malware that was created to steal your credentials and credit cards – meaning the people who created it spent a lot of resources to make it as dangerous as possible.
