Alsulics.exe Virus – How to Remove It

What is Alsulics.exe?

AlsulicsApplication or AlsulicsService.exe appeared in Task Manager causing high CPU usage, your security tool flagged it as Trojan.Altruistik, or you found unfamiliar programs installed on the same date as something you deliberately downloaded. Read this removal guide carefully – Alsulics.exe is not a Windows system file and it should not be on your device.

AlsulicsApplication is an unwanted software cluster documented by Gridinsoft, HowToRemove.guide, and Trojan Killer as a malware bundle associated with cryptocurrency mining and Trojan behavior. The primary process, AlsulicsService.exe, is detected by Gridinsoft Anti-Malware as Trojan.Win64.Altruistik and by other security tools as Trojan.Altruistik. Its most visible effect is sustained high CPU usage, which is the symptom of a coin miner running in the background. AlsulicsService.exe registers itself as a Windows service to ensure it restarts after deletion, meaning simply removing the file or uninstalling the visible application does not produce a complete fix – the service entry and any scheduled tasks must also be removed for the infection to stop returning. The bundle frequently arrives alongside other unwanted programs installed on the same date, including OB (OneBrowser), Web Companion, DealPly, and browser extensions, and is linked to adware-associated .co.in domains used for ad-revenue infrastructure.

How Did I Get Alsulics.exe?

Here is how the AlsulicsApplication bundle typically reaches a device:

• Software bundling with free downloads from unofficial sources – The most documented delivery route: a free program downloaded from a third-party site installs AlsulicsApplication and its companion programs as bundled additions through software bundling. Accepting the default or Recommended installation option installs the entire bundle without a clear separate disclosure of each component.
• A same-day bundle of multiple unwanted programs – A distinctive pattern for this cluster: checking the installed programs list sorted by install date typically reveals Web Companion, DealPly, OB/OneBrowser, or unfamiliar browser extensions all installed on the exact same day as the AlsulicsApplication. This same-day pattern confirms the programs arrived as a coordinated bundle rather than separate deliberate installs.
• A deceptive download prompt or fake update on a low-quality site – A pop-up on a streaming or download site presenting a browser extension or software update delivers the Alsulics bundle alongside or instead of the claimed tool.
• Pirated software or cracked applications from unofficial sources – Cracked software packages embed the AlsulicsApplication bundle in the installer, where all components install silently during setup.

What Does Alsulics.exe Do?

The infection operates on several simultaneous tracks. Here is the full documented picture:

• Mines cryptocurrency using the device’s CPU without authorization – The primary confirmed function is cryptojacking: AlsulicsService.exe exploits the infected device’s CPU to mine cryptocurrency for the operators, causing sustained high CPU usage, elevated fan noise, overheating, and significantly slowed performance during the mining period.
• Registers as a Windows service to survive uninstall attempts – AlsulicsService.exe registers itself as a persistent Windows service, meaning that even after the visible AlsulicsApplication is removed from the installed programs list and the exe file is deleted, the service entry relaunches the malware component on the next system boot – causing the CPU behavior and security alerts to return.
• Trojan behavior as classified by Gridinsoft – The Altruistik-family classification means the malware can perform additional actions beyond mining, potentially including credential collection, ad injection through associated browser components, and downloading further malware.
• Bundled components modify browser settings and inject ads – Web Companion, DealPly, OB/OneBrowser, and associated browser extensions installed alongside Alsulics collectively redirect browser traffic through adware-associated .co.in domains, inject advertisements, and collect browsing data through trackers.

How to Remove Alsulics.exe

Removal must address the service, the application, and all same-day bundled components. Do not delete only the exe file and stop – the service will relaunch it. Start by opening a Command Prompt as administrator and running: sc qc AlsulicsService to confirm the service exists and note its binary path. Then stop and delete the service: sc stop AlsulicsService followed by sc delete AlsulicsService. Open the installed programs list (Settings, then Apps, then Installed apps), sort by install date, and uninstall AlsulicsApplication and every other program installed on the same date that you did not deliberately choose, including Web Companion, DealPly, OB/OneBrowser, and any unfamiliar items. Open Task Scheduler (taskschd.msc) and delete any scheduled task pointing to an Alsulics-related path. Open Chrome’s extension manager and remove any extension installed on the same date. Run a full scan with a dedicated anti-malware tool – SpyHunter is confirmed to successfully remove the Alsulics cluster – to catch any remaining components, registry entries, or service remnants. Reboot and verify that Task Manager no longer shows high CPU tied to Alsulics processes. Follow the complete removal guide below this article for the full step-by-step process.

If any threats have been removed, it is highly recommended to restart your PC.

Step 2: Clean any registries, created by Alsulics.exe on your computer.

The usually targeted registries of Windows machines are the following:

• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

You can access them by opening the Windows registry editor and deleting any values, created by Alsulics.exe there. This can happen by following the steps underneath:

---

1. Open the Run Window again, type "regedit" and click OK.

---

2. When you open it, you can freely navigate to the Run and RunOnce keys, whose locations are shown above.

---

3. You can remove the value of the virus by right-clicking on it and removing it. Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.

Step 3: Find virus files created by Alsulics.exe on your PC.

1.For Windows 8, 8.1 and 10.

For Newer Windows Operating Systems

1: On your keyboard press  + R and write explorer.exe in the Run text box and then click on the Ok button.

2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.

3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:

N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.

2.For Windows XP, Vista, and 7.

For Older Windows Operating Systems

In older Windows OS's the conventional approach should be the effective one:

1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.

2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.

3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.

Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
