Svchost.exe virus removal guide
What is svchost.exe?
svchost.exe is the generic name of a legitimate Microsoft Windows process that can be found running in the Task Manager. Typically, there is more than one Service Host process running at once, since separate processes handle separate groups of services. For example, one svchost.exe process might be dealing with services relating to network services, whilst another might be dealing with services relating to remote procedure calls, and so on. In many cases, however, cyber criminals disguise malicious files/processes using names similar to those of legitimate processes.
svchost.exe is an important part of the operating system that hosts various services. It is used to group/allocate services so that they use less system resources. Typically, the svchost.exe file can be located in "%SystemRoot%\System32\svchost.exe" or "%SystemRoot%\SysWOW64\svchost.exe". If the svchost.exe is placed elsewhere, this indicates that it might be a virus. If the filename is incorrect (for example, the file is named svhost.exe [without the "c"] or svchosts.exe [with an additional "s"], this might also indicate a problem. Service Host's location can be checked by right-clicking any of its processes in Task Manager and selecting the "Open file location" from the drop-down menu. Additionally, malicious processes disguised as official and legitimate when running in Task Manager often have a graphical icon beside them, when in fact the icon should be a default system icon. Typically, cyber criminals disguise high-risk malware, for example, malicious programs such as Netwire RAT. They attempt to infect computers with programs that help them to proliferate additional malware (such as ransomware), steal personal details (including banking information), control computers remotely, and so on. They use these techniques to generate as much revenue as possible, often causing financial/data loss, problems with privacy, and so on, for unsuspecting users. If you have any reason to believe that the running svchost.exe process is not a part of Windows (it is perhaps named svhosts.exe, is not in the correct location, etc.), remove it as soon as possible.

svchost.exe is not the only legitimate process that can be used to disguise malware. Other examples are gwx.exe, csrss.exe and msfeedssync.exe. There are cases whereby virus detection engines list "false positive" results - they detect legitimate files as threats. In some cases, this results in removal of harmless or important files. This is due to mistakes in databases (incorrect filenames). Therefore, ensure that a file or process is actually malicious before it is removed.

How to avoid installation of malware?
Ignore emails that are received from unknown addresses, contain attachments (or web links), and are irrelevant. The safest way is to simply ignore them. Furthermore, we advise that you avoid downloading files and software using third party downloaders, unofficial pages, and other tools mentioned above. All files and software should be downloaded from official websites and using direct download links. Update software legitimately using tools or implemented functions provided by official software developers. Do not use third party, fake update tools. Software 'cracking' tools are illegal and are often used to proliferate infections. Finally, computers are safer when reputable anti-virus or anti-spyware software is installed. These programs should be updated and virus scans performed regularly. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Spyhunter for Windows.
