What’s RtkAudUService64.exe (Realtek HD Audio Universal Service)? Is it safe or a virus?

Realtek is a common brand associated with PC audio. On our own PCs here in Austin, Texas at SpyShelter cybersecurity labs, we often see Realtek processes running. Processes from this company based in Taiwan should be safe for your PC, and you'll find they are necessary to run if you want to hear any audio coming out of your speakers or headphones. So what exactly does this Realtek software with an extremely long name do for your PC?

This process is responsible for providing various audio-related functions such as volume control, sound effects, and audio device management. It runs in the background and is typically not visible to the user. It's a legitimate process developed by Realtek and is not known to pose any security threat.

So, turn up those tunes and keep rocking on your PC because RtkAudUService64.exe should be a completely safe process!

But, why is this process signed by Microsoft if it's made by Realtek? That's because Microsoft signs some Windows System software, like drivers, because Microsoft checks them to make sure they are stable and safe for your PC.

The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable?
