Ive been trying for weeks to remove an svchost.exe virus which appears to be bitcoin mining using my GPU, I first noticed when my GPU load was at 98% load when idle and realised that if I just ended the svchost.exe in processes it would stop until I restarted my PC, however I need rid of this but I've tried everything I could find.
If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.
If there are additional problems with your system, such as any of those listed above or other system issues, then run the fixdamage tool included with Malwarebytes Anti-Rootkit and reboot.
Also, as far as I'm concerned, the svchost.exe virus has stopped automatically running every time I restart my PC and I can't find the svchost.exe virus in the folder where it used to always be and un removeable (C:\Users\Sean\AppData\Local\Temp). I think my PC may be back to normal?
Please look over what was found......especially any folders, we're going to permanently delete it all in the next step....if there's something you may want to keep...please let me know and I'll explain to why it shouldn't be on your system.
You can click on the question mark (?) in the upper left corner of the program and then click on Options. You will then be presented with a dialog where you can disable various detections. These options are described below:

Occasionally on one of my web servers svchost.exe runs around 60-80% running the DNS Client Service. This is on a Windows 2008 Web Server machine (patched up all the way) handling around 10M page views a day and around 5M unique users monthly.
I sometimes see it running on one of two servers in my farm, while handling the same amount of traffic as the other machines so I think it might be okay to disable it... Keep in mind that a server affected by it running close to 90% CPU while the others at 15%.
Disabling the DNS client service is going to make the server completely unable to resolve any DNS queries at all. This is not a good idea, IMHO. For starters, that means at a minimum the server will not be able to do any Windows Updates. But also, almost everything any computer does that involves networking of any sort requires DNS queries in order to function properly.
DNS Client Service serves mainly as a DNS cache as it's service name "DNS Cache" suggests. Turning it off can slow down DNS name resolution.
Common browsing experience shouldn't be harmed. But there might be some processes on your web servers which rely on DNS name resolution. Then their response times could raise only because of repeated DNS queries to your DNS authority.
Disk usage is a measure that operating systems (in this case Windows 10) have developed to know what percentage of the disk (where the operating system is installed) is in use, which increases or decreases depending on the applications that are running simultaneously. On the other hand, svchost.exe is a host service process that must always be active, which generally has normal behavior on the computer but can sometimes exponentially increase disk usage. Here you will know the reason for this problem and various ways to solve it.
Each disk performs write and read processes; these can have a maximum write/read speed on average of 100 Mbps to 150 Mbps. Each application active on the computer is constantly reading or writing, so if the sum of all these applications reaches the maximum write/read speed of the disk, it will have represented a 100% disk usage.
Depending on the application, it will take up disk usage, most of them take up very little disk usage. However, others are quite demanding in this regard. Sometimes, some processes that tend to take up very little disk usage change their behavior and start to be problematic; an example is svchost.exe which, in a normal state, will consume very little Mbps on the disk. However, there may be factors that alter this service host and that it becomes a process that occupies a high percentage of disk usage and that in this way your computer works very slowly.
Antivirus can help you detect which malicious file is causing the virus to activate. Windows, through its antivirus software (Windows Firewall), can also do it; Below I will describe the steps to make a scan using this tool:
If you don't keep your operating system updated, in addition to reducing your security, it can make processes (like svchost.exe) not work as indicated, facilitating errors and problems. To check if you have pending updates in Windows 10, follow these steps:
If Windows installed updates, you have to wait. Depending on the size of the update, you will have to wait just a few or some minutes. Afterward, restart your computer and check if svchost.exe works as it should.
You can end any svchost process from the Task Manager, but you should bear in mind that any Windows process that you end through Task Manager will automatically start again when you restart your computer.
Once inside the Services manager, you should search for the "Windows Update" service, right-click on its name and choose the "Properties" option. This will open a window from which you can disable the automatic Windows Update service.
Windows has a tool called Troubleshoot that allows you to fix Windows update problems automatically. To use this tool, just type "Troubleshoot" from the Windows menu and click on its shortcut. Once this is done, you will see the "Windows Update" option within the "Troubleshoot" menu. Click on the "Windows Update" option and the tool will guide you through the repair process.
Disabling the background intelligence transfer service can considerably reduce disk usage, but you should bear in mind that if you use the "Task Manager" to end the process, it will automatically start again every time you turn on your computer, therefore, I recommend to disable the service through the Services Manager. Below I will show you how to do it.
Once inside the Services manager, you should search for the "Background intelligence transfer service" service, right-click on its name and choose the "Properties" option. This will open a window from which you can disable the service.
If with the previous methods you did not manage to solve the problem, you can choose to reformat your device. This method will delete all the information on the disk and create a clean installation of the operating system, thus suppressing any errors, viruses, or fragmented segments on the disk that may be affecting the performance of the device.
To perform a clean installation of Windows 10, you will need to download the Windows 10 installation tool from its official website. The most common and recommended method is to use a USB to store this installation tool. Once you have created your Windows 10 installation device, you will need to boot from USB to begin the installation. Now all you have to do is select the "Custom" installation type, format the device, and follow the steps indicated by the Windows 10 installer.
As I mentioned earlier, performing a clean installation of Windows 10 will erase all the information you had stored on your device, however, this problem is easy to solve thanks to Recoverit. This software is capable of reconstructing and recovering all the information on a disk-based on the residual information. It will be enough to do a couple of clicks and the software will take care of recovering your data. You can download the software for free from its official website Below I'll show you how to use it.
Windows 10 was designed to make the user experience extremely comfortable and efficient, to achieve this goal, it was necessary to implement services that were responsible for performing optimization tasks automatically, but there is also the possibility that these services hinder the performance of your computer. Fortunately, this problem is easy to solve, on the other hand, if the source of the problem is that your operating system is in bad condition, you can use Recoverit to restore and repair all the information on the disk with great ease.
To begin with, you need to restart the device, and if still keeps consuming the space, you should force-stop svchost exe. In addition, space consumption can occur due to malware or virus, so download an anti-virus program as well.
Svchost.exe is a generic and legitimate Windows process that loads several other critical services for proper Windows operation. But in several cases users are complaining that Svchost.exe is hogging their CPU or Memory resources without obvious reasons e.g. at moments when the user doesn't run any programs.
Many viruses or malicious programs can cause the svchost.exe high CPU/memory usage problem. So, before you continue to troubleshoot the Svchost.exe high CPU usage problem, use this Malware Scan and Removal Guide to check and remove viruses or/and malicious programs that may be running on your computer.
Svchost.exe is a process that is needed by several services or programs in order for them to run. So, determine which service or program runs under the svchost.exe process and is hogging your system's CPU and memory resources and then proceed to disable or totally uninstall that program (or service).
In other computers, the svchost.exe high usage problem may occur when Windows searches for updates (in the background). In order to troubleshoot high CPU usage problems during Windows Update, perform the following steps.
The Windows Update Store folder (commonly known as "SoftwareDistribution" folder), is the location where Windows stores the downloaded updates. If this folder is corrupted, then you will face problems during Windows Update. So, first try to force Windows to re-create a new empty SoftwareDistribution folder. To do that:
