Vghost.exe Miner: what it is and how to remove it

Legitimate programs use a lot of processor time only while they work for you:

• a game
• a video export
• a Windows update
• an antivirus scan

If Vghost.exe does it constantly, including when you are away from the PC, it is most likely mining cryptocurrency or running another background job for someone else.

Look at the file's location and digital signature, and at what starts it: the Startup list in Settings, Task Scheduler and services. A process with no clear owner, an unsigned file and a hidden restart entry should be removed and the PC scanned offline.

You can, but only after you have stopped what restarts it, otherwise the file is simply downloaded or copied back. Note the full path of Vghost.exe first, using Open file location in Task Manager. Then disable its startup entry or task, end the process and delete the folder.

If Windows says the file is in use, restart in Safe Mode and try again. Never delete a file from C:\Windows\System32 that is signed by Microsoft; if that is where the busy process lives, the cause is something else using a genuine Windows file.

You can, but it is rarely enough. Vghost.exe is the visible part of Vghost.exe Miner; a scheduled task, a service or a startup entry usually starts it again, and some versions restore the file within minutes. Deleting it while it runs may also fail.

Run the Microsoft Defender offline scan instead, which removes the file and its startup entries before Windows loads. Then check Task Scheduler and Startup apps for anything still pointing to the old location. Restart afterwards and confirm the file does not return.

In everyday language, yes: Vghost.exe Miner is malware, a program that runs without your consent. More precisely, the reports point to a cryptominer, based on what people saw: Vghost.exe using the processor or graphics card at full load. It is not part of Windows and no legitimate program behaves this way while hiding from the user.

It should be removed, and the PC checked for other programs that may have come with it. Because there is no public analysis yet, we cannot list everything it does; the removal plan in this guide is written to cover the usual places this kind of malware uses to start and hide.

There is no evidence either way yet, because Vghost.exe Miner has not been analysed in public. The reported sign, Vghost.exe using the processor or graphics card at full load, does not show theft by itself. However, malware of this kind is often installed together with a password stealer, which works in seconds and leaves nothing to see.

The cautious approach costs little: once the PC is clean, change the passwords saved in your browsers from another device, starting with e-mail, then banking and payment accounts. Sign out of all sessions and turn on two-step verification. If a bank card was saved in the browser, ask the bank about a replacement.

We cannot name a source for Vghost.exe Miner yet, because no one has traced its distribution in public. In the cases we see, a cryptominer most often comes with pirated software, activators, game mods and cheats, or with downloads from sites that repackage free programs. Removable drives are another route for self-spreading kinds.

Your own history is the best clue: what did you install or plug in shortly before you first noticed Vghost.exe using the processor or graphics card at full load? Whatever it was should be removed together with the malware and never reinstalled from the same place.

Restart the PC first; some changes only take effect after a reboot. Then open Task Manager and check the Processes and Startup apps tabs for anything unfamiliar using the processor, disk or network. If something remains, run the Microsoft Defender offline scan once more.

Slowness can also come from a second infection installed alongside Vghost.exe Miner, or from programs that were damaged during the clean-up. If nothing helps, back up your files and reset Windows. Copy only documents and photos before a reset, and scan the copies.

It depends on the hardware and how hard the miner runs, so there is no single figure. A miner that keeps a desktop processor or graphics card busy around the clock can noticeably raise a household power bill over a month, and laptops lose battery life fast.

Some miners limit themselves to part of the available power to stay unnoticed, which lowers the cost but also hides the problem longer. Removing it is the only fix. Afterwards, idle use should fall back to a few percent.

It is a good idea, even for malware that does not spread by itself. The same download, USB stick or loader may have been used on other PCs in the household, and shared folders can carry files between them.

Run a full scan followed by the Microsoft Defender offline scan on each Windows PC that shared drives or files with the infected one. Do not copy programs or installers from the infected PC until it is clean, and change Wi-Fi and router passwords if they were saved on it.

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 Vghost.exe Miner, 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.
