An icon appeared in my task bar, which requests a restart of my computer to install an update….the update was not requested by me, and is from “RealTek”. I don’t know what to do? If I don’t install it (by restarting my computer), how do I get rid of it? Is it dangerous?
Realtek also provide Networking components and drivers for Computers.
RealTek the provider of your audio drivers. It’s what allows your computer to run sound files/etc.
You’re likely fine. Do a virus scan to be sure but RealTek is a legit company and keeping those drivers up-to-date is relatively important.
