Svchost.exe virus removal guide
What is svchost.exe?
The svchost.exe is a generic name of a legitimate Microsoft Windows process that can be found always running in the Task Manager. Typically, there is more than one Service Host process running at once, separate processes handle separate groups of various services. For example, one svchost.exe process might be dealing with services related to network services, another one might be dealing with services related to remote procedure calls and so on. However, there are many cases when cyber criminals disguise malicious files/processes by using names that are similar to the names of legitimate processes.
Svchost.exe is an important part of the operating system that hosts various services. Simply said, svchost.exe is used to group/allocate services so that they would use less of the system's 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 somewhere else, it might be a virus. Or if the filename is not correct, for example, the file is named svhost.exe (without the "c") or svchosts.exe (with additional "s"). Service Host's location can be checked by right-clicking the any of its processes in Task Manager and selecting the "Open file location" from the dropdown menu. Additionally, malicious processes that are disguised as official and legitimate, when running in Task Manager often have some graphical icon next to them, when their icon supposed to be a default system icon. Typically, cyber criminals disguise various high-risk malware, for example, malicious programs like Netwire RAT. They attempt to infect computers with programs that would help them to proliferate additional malware (like ransomware), steal personal details (including banking information), control computers remotely and so on. Basically, they use them to generate as much revenue as possible, it often causes people financial, data loss, problems with privacy and so on. If there is any reason to think the running svchost.exe process is not a part of Windows (it is named something like svhosts.exe, it is not in its location etc.), then we recommend to remove it as soon as possible.
