wbengine.exe is a legitimate Microsoft Windows component designed to manage the update workflow. It is digitally signed, located in C:\Windows\System32, and its tasks include checking for updates, downloading patches, installing them, and applying reboot steps as needed. Normal operation should not indicate malware.
wbengine.exe itself is not a virus when it resides in the correct system path and is signed by Microsoft. However, malware can masquerade as wbengine.exe, so you should verify the file location, signature, and behavior. Unusual activity or a nonstandard path warrants a full malware scan.
