I'm using the surface pro 6 which is not the most bug free device. Recently my camera+IR face scanner open it self while using it 2 times in 2 days and I have to restart to get it turn off thought it was a bug and never thinking about it. But when I'm check in privacy>camera I found svchost.exe which I haven't noticed it before. After playing with it for a while it seems when ever I use camera+IR to scan my face to sign in with windows hello this svchost access the camera. I cannot find is this a regular thing to happen or not ,some say it is some say it is trojan I'm confused. Scan my device with both malwarebyte and windows defense and found nothing. Is this a normal windows update/camera bug or something that I need to concerned?
