I saw this problem was solved many times on the forums, but didn't want to follow the steps in case they were meant only for the other people's unique situations. So I decided to make an account and ask for help. These ads usually play around 3-4 am, but happen throughout the day and in the volume mixer, its shown its done through chrome. Also recently, chrome has been eating up a lot of CPU usage even when it's not doing anything, so I think thats related. Used malwarebytes, Kaspersky, doesn't detect anything. Thanks in advance.
