Prime.exe – a nasty Trojan-based threat capable of anything

Each Trojan infection poses a serious danger to the computer that it has managed to compromise. The reason is, this type of Trojan is capable of literally anything malicious you can think of. Not only can the Trojan spread all over the Internet with the help of various camouflaged transmitters, but it can also launch different criminal processes and be used for the completion of all sorts of sneaky and highly damaging tasks.

In most cases, the contamination happens when the users are tricked into clicking on some seemingly harmless link, ad, email attachment, pop-up or misleading page redirect, which secretly deliver the Trojan. The stealthiness of the Trojans is unmatched by most other types of computer threats. That’s why it is no wonder that new Trojan such as Prime.exe and Energy.exe are some of the favorite tools of the cyber criminals. With their help, the hackers can corrupt important user data, keep track of the victim’s online and offline activities, steal sensitive information like passwords, login credentials or banking data and even spread other viruses like ransomware or spyware.

The worst thing about being infected with a Trojan is that you may not know about it for a long time. If there is no reliable antivirus program or its virus definitions have not been updated for some time, it may take weeks or even months to detect such an advanced Trojan on your computer. The reason is that Trojans typically show no symptoms that can give them away and indicate that something malicious is running on your system.

That’s why it is extremely difficult to locate the threat manually. A good security program, however, can scan your machine in depth, and notify you about any harmful activity that might be running in the background. With this in mind, the purchase of reliable and reputed security software can be considered a good investment in your safety. And if you run regular scans with it, it may save you from threats like Prime.exe and other nasty infections that you may have no clue about.

If you want to eliminate Prime.exe from your computer fast, our first recommendation is to try to:

  • Open the Control Panel from your computer’s Start menu.
  • Then, in the Control Panel, you need to go to Programs and Features and choose Uninstall a Program.
  • A list of all the installed applications should be available to you. Look carefully for software that you don’t recall installing, is out of date, or that you seldom use.
  • Remove Prime.exe and anything else that seems untrustworthy. When you click Uninstall, the notice below may display on your computer. Select NO and finish the removal process.

Once you have finished this, you should have reduced the danger significantly. Even so, you should be aware that Prime.exe may have also spread harmful components to other parts of your system. Therefore, we recommend you to use the following guide to ensure the removal of the Trojan and erase any traces of it from your PC.


You will need to restart the computer throughout the steps outlined below. Therefore, to avoid the need to search for the removal instructions after every restart, we suggest saving this Prime.exe guide in your browser’s bookmark, so you can quickly go back to where you left off. It’s also possible to follow the instructions on another device, if that is more convenient to you.

Now, before going further, you should restart your computer in Safe Mode. In this way, it will be simpler to locate and remove Prime.exe and its harmful processes and files from the various system locations.

If you don’t know how to reboot in Safe Mode, please use the guide from this link.

To see all active processes on a Windows PC, including any potentially dangerous ones, you must open the Task Manager by using the CTRL+SHIFT+ESC key combination. From there, click on the Processes tab and do a thorough search for anything odd on the list of processes.

Please note that the processes related to Prime.exe may hide under different names. It is thus advisable to search for telltale indications of malware, such random characters and misspelled words in the name of an otherwise legitimate-looking process. Moreover, you should consider the CPU and memory utilization, since the presence of a malicious program may be indicated by a large system resource usage for no apparent reason.

A good method to tell whether a running process is hazardous is to right-click on it and choose the Open File Location option:


The files, which are linked to that process, will be in a folder. Scan them for malware with the online virus scanner, which is accessible for free below:Shortcode

Even if just one file from the scan is flagged as a threat, this should be enough to stop the whole process. You may do this by navigating to the Processes tab, then right-click on the problematic process, and choose the End Process option. After you have completed that, you must also remove the files from their File Location folder.

Please keep in mind that there could be several suspicious-looking processes in your Task Manager. Therefore, we advise you to use the scanner to ensure that all processes that look questionable are checked, and you ensure that your computer only has genuine processes running on it before you move to the next step.

If your computer has been compromised by Prime.exe, be sure to check which applications and processes start up when your machine boots. Sometimes, Trojan infections may install harmful starting programs that activate as soon as the user turns on their computer.

So, to check if this is happening on your machine, click on the Start menu button and type msconfig in the search bar. Next, press Enter, and the following window should appear:


Click on Startup and check for suspicious-looking Startup items with “Unknown” Manufacturer or strange names. Uncheck the checkbox of any startup items you think are linked to Prime.exe and click OK to apply the changes.


To further ensure the PC’s safety, be sure to inspect the Hosts file if you suspect that another major danger (like ransomware) is operating on your computer, or if the system has been hacked. 

In order to access the Hosts file, copy this in the Windows search bar and press Enter:

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

In the file, search for Localhost and check if any malicious IP addresses have been added beneath  like the image below:

hosts_opt (1)

If you see anything odd in your Hosts file under Localhost, please feel free to drop us a line in the comments section, and we will try our best to assist you. If there is nothing disturbing, close the file and move to the last step of this guide.


The last place you should look for traces of the Trojan is in the registry. In order to gain persistence and remain on the machine for a long time, threats like Prime.exe may use assistance components and files. Therefore, you must carefully search the registry for any threat-related harmful files and remove them without removing anything else.

Professional-level users can typically do this job without help but, ordinary users may mistakenly believe their computer’s legitimate files are malware and remove them, inflicting more damage than good. 

Therefore, in the event that you haven’t dealt with registry files before, but you still want to perform a manual removal of Prime.exe, this is how you should proceed:

  • Open the Registry Editor by searching for Regedit in the Start menu’s search box.
  • Click on Enter to launch the Registry Editor
  • Use CTRL+F in a combination to open a Find box.
  • Type the Trojan’s name in the Find box and press Find Next.
  • Right-click to remove any entries you find. 

If the Find feature is unable to locate anything in the registry matching the Trojan’s name, use the left-hand panel of the Editor to manually go to each of these directories:

  • HKEY_CURRENT_USER—-Software—–Random Directory. 
  • HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
  • HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

Look for strangely named files and folders that have been added lately and remove them, if you suspect they are part of the virus.

If you have tried everything and the Prime.exe is not removable manually, even after repeating the steps in this guide, you should download our recommended anti-virus software and do a complete system check. Professionals have warned that, in some cases, computer users who are infected with Prime.exe may not be able to clean up their system unless they employ specialized antivirus software.
