How do I know if my Service Host is a virus?

First, it’s important to understand that service hosts are not viruses. They’re just programs that run on your computer and allow the software to be installed or updated. 

A virus is a piece of software that infects other files, programs, and data. Malicious software can be written to do many things, such as steal information, change settings on your computer, or even damage your hard drive.

To test whether or not your computer has been infected with malware, run antivirus software on it first. If no problems are found after running scans for malicious software, you should feel safe.

Another way to check if your Service Host or svchost.exe is a virus is by checking its location. Any other location should call for suspicion unless you moved it. It will usually be located in the following folder: %SystemRoot%\SysWOW64\ or %SystemRoot%\System32

If the problem persists, you may try to restart the computer in Safe Mode. This will help you isolate the cause of the problem and allow you to run an antivirus scan on your system again.
