RevServicesX is a Trojan Horse that is used to mine cryptocurrency without users' permission
RevServicesX trojan is a malicious program that can easily affect your PC's performance as it tends to use most of its CPU's resources to generate cryptocurrency.
This program infiltrates the system similarly to other types of malware - without a user's knowledge or consent. Additionally, it drops app_loeader.exe and SystemUpdate64x.exe processes that are launched as soon as the system is rebooted.

How RevServicesX got on your PC
From our report of Jul 2018 · not reviewed since
Virus developers have been relying on many different ways for spreading malware like this.
The most common ways used by Trojan developers are insecure spam email attachments that have a malicious attachment added to them to infect target users. Trojans can infiltrate the system stealthily, the minute you open the "invoice", "image" or similar attachment.
To avoid such fake email messages, you need to double check them first. Make sure you check the sender, his or her email address and similar information. Besides, always think have you ever dealt with the company the sender is representing. Typically, people download attachments from companies they have never heard of.
Also, do not forget to be cautious when downloading and installing freeware. While the most people tend to skip through some important steps, you should never choose Quick or Default options just to save your time while installing software on your system.
Rushing thru such important steps might cause a lot of trouble, so make sure you opt for Custom or Advanced installation mode only. At this point, you should deselect unwanted components and be sure that you only get the software you need.
How to check the PC for RevServicesX
- File:
app_loeader.exe
How to remove RevServicesX
A loader's job is to install other malware, so treat the PC as infected with more than one program until the scans are clean.
Step 1: Check where app_loeader.exe runs from and stop it
In Task Manager (Ctrl + Shift + Esc) find
app_loeader.exeon Processes, right-click it and choose Open file location before ending anything.Windows' own files live in
C:\Windows\System32; the same name in%AppData%, %Temp% or C:\Users\Public is an impostor. If the folder is wrong, right-click the process again, choose End task and delete the file.If it starts again within seconds, a task or another process restarts it, so run the scan step in Safe Mode. Task Manager works the same in Windows 11 and Windows 10.

Step 2: Delete scheduled tasks that bring it back
Programs like RevServicesX add a scheduled task so they return after an uninstall or reopen a page at every sign-in. Start Task Scheduler, open Task Scheduler Library and sort by Last Run Time to see what ran recently.
On the Actions tab, a program in a user folder, a script or a web address is a warning sign; right-click such a task and choose Delete.
Tasks with names copying Google, Edge or Windows updaters but pointing to an odd folder are typical. The tool looks the same in Windows 11 and Windows 10.
Windows 11: Task Scheduler Library, the task selected, the Actions tab shows the file it runs. Full procedure with screenshots: Remove what malware leaves behind in Windows
Step 3: Remove it from startup
Press Ctrl + Shift + Esc to open Task Manager and select Startup apps (Windows 11) or the Startup tab (Windows 10). Disable entries you do not recognise, especially ones with no publisher or with a name that copies a Windows component.
Right-click an entry and choose Open file location to see where it runs from: programs in
%AppData%or%Temp%deserve a closer look. Some entries are not listed there but in the registry Run keys, which the procedure below shows how to check.Full procedure with screenshots: Stop apps from opening at startup On uGetFix
Step 4: Delete the folders left behind
Uninstalling often leaves the program's folders, and some threats reinstall themselves from them.
Press Windows + R, type
%LocalAppData%and press Enter, then do the same for%AppData%and %ProgramData%, and look for folders named after RevServicesX, its publisher or created on the day the problem started. Delete those folders, and check C:\Program Files and C:\Program Files (x86) too.If Windows says a file is in use, end it in Task Manager or delete the folder after a restart in Safe Mode. The folders are the same in Windows 11 and Windows 10.

Step 5: Scan the PC, then run the offline scan
A scan finds the parts of RevServicesX that the manual steps cannot see. In Windows Security > Virus & threat protection > Scan options, start a Full scan and quarantine what it reports.
Follow it with Microsoft Defender Antivirus (offline scan) > Scan now, which restarts the PC and checks the disk while Windows and the malware are not running.
It takes about 15 minutes and works the same in Windows 11 and Windows 10. If either scan finds something, run the full scan again after removal until it comes back clean.
Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan
Step 6: Change passwords from another device and sign out other sessions
RevServicesX can copy saved passwords, cookies and session tokens and send them out in seconds, so cleaning the PC does not undo the theft.
Change your passwords on a device that was never infected, starting with the e-mail account, since every other reset goes through it. On each account, end all other sessions and check the recovery e-mail, phone number and forwarding rules.
Then turn on two-step verification. Sign in on the Windows 11 or Windows 10 PC again only after the offline scan is clean.

After removal: passwords, accounts and prevention
Secure your accounts after the clean-up
Assume that whatever was saved in the browsers on this PC while the PC showed an unfamiliar process called app_loeader.exe in Task Manager has been copied:
- passwords
- cookies
- autofill data
Work from a clean device, or from this PC once the offline scan finds nothing.
Start with your main e-mail account, because it can reset everything else, then banking and payment, then social and gaming accounts. Change each password, sign out of all sessions and turn on two-step verification: Turn on two-step verification / secure a hacked account.
The full order, including crypto wallets and card replacement, is in securing your accounts after malware.
Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files.
More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
Questions about RevServicesX
What is app_loeader.exe and why is it running?
Every process is started by something:
- a program you installed
- a Windows service
- a scheduled task
- a startup entry
To learn why app_loeader.exe runs, find its file with Open file location in Task Manager, then look for an entry pointing to that file in Settings > Apps > Startup and in Task Scheduler.
Sort Installed apps by date to see what arrived when the process first appeared. Once you know the owner, you can decide whether to keep it, switch it off at startup or uninstall it completely.
app_loeader.exe keeps coming back. What should I do?
A process that returns after you end it has a restart mechanism, and that is a reason to treat app_loeader.exe as unwanted. Check Settings > Apps > Startup, Task Scheduler and the Services list for entries pointing to its folder, and disable them.
Look in Installed apps for anything added the same day and uninstall it. Then delete the folder and run a Microsoft Defender Offline scan, which works before Windows starts and can remove files that are locked or hidden while the system is running.
Is app_loeader.exe a virus?
If it sits outside the Windows and Program Files folders and your antivirus links it to RevServicesX, yes. app_loeader.exe is the file name used by this trojan. Some trojans borrow the names of real Windows components, so the name alone does not decide it:
- right-click the process in Task Manager
- choose Open file location
- look at the folder and the publisher under Properties > Details
A file in a user folder with no publisher is the trojan. Do not delete it by hand while it runs; use the offline scan in the plan above.
Why can't I find RevServicesX in antivirus databases?
Because it is new or because it is listed under a different name. Antivirus companies name threats after the family they belong to, and a program that appears as RevServicesX on your PC may carry a generic or unrelated label in their databases.
Many new samples are first detected only by behaviour, without a family name. What you saw, an unfamiliar process called app_loeader.exe in Task Manager, is enough to act on:
- end the program
- remove its startup entry
- run a Microsoft Defender offline scan
- secure your accounts
A detection name from a scan is worth noting for later.
My antivirus was on. How did a trojan get past it?
Antivirus programs see a file only when it is written or run, and criminals test each new build against popular scanners before release. Detection catches up within hours or days, which is often after the first victims ran it.
Archives with passwords, installers that fetch the malware later, and scripts run through PowerShell make the job harder. That is why behaviour such as downloading cracks or pasting commands matters more than any setting. Keep Windows and Defender updated, and turn on Reputation-based protection in App & browser control.
Do I need to reinstall Windows to get rid of RevServicesX?
Usually not. A thorough clean-up is enough when the offline scan finds nothing afterwards and you do not see an unfamiliar process called app_loeader.exe in Task Manager again. A reset is the safer choice if an attacker had remote control, if security tools were switched off, or if detections come back after every clean-up.
Windows 11 can reset itself without a USB stick under Settings > System > Recovery > Reset this PC. Copy documents and photos out first and scan the copies. A reset does not change passwords or undo stolen data, so the account steps still apply.
Should I check my other computers too?
Yes, it takes little time and removes doubt. RevServicesX itself usually stays on one PC, but the download that carried it may have been copied to other computers, shared drives may hold the same installer, and an attacker who had access could have tried saved passwords on other devices.
Run a full scan on every Windows PC in the home or office, check shared folders for the original download, and change Wi-Fi and router passwords if they were stored on the infected machine.
Should I report RevServicesX?
Report it if you lost money, if accounts were taken over, if you are a business, or if the trojan came through a scam call. A police or national cybercrime report gives you a reference number for your bank and insurer and helps link cases.
You do not need to report a trojan that antivirus blocked before it ran. Before reporting, write down the dates, the detection name, file names and any messages or transactions linked to the attack; screenshots of antivirus alerts are useful evidence. The country list is in the report section above.
I found AnyDesk or ScreenConnect that I did not install. Is that RevServicesX?
Not necessarily RevServicesX, but it is a warning sign. These are legitimate remote support tools, and criminals use them as ready-made backdoors, especially after tech support scams or fake invoice calls.
If you did not install it and no one you trust set it up, uninstall it, change passwords from a clean device and check your bank account. If someone connected to your PC through it, follow the steps for remote access trojans and consider a Windows reset. Installed apps sorted by date shows when it appeared.
Will Fortect remove RevServicesX?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For RevServicesX, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
