Hello, just today I got an ad in spotify that was a fake windows security window (in the ad box) and said my computer was infected. I know virus fake that and am not saying my computer is infected. At first I just dismissed it cause it disappeared and said oh maybe my laptop has a virus (I don't have security on that laptop cause I hardly use it) and went on with my day. Just a few moments ago I saw an ad in spotify (on my secured Desktop) with a web address that said "failed to load..." I dont remember the full message but it listed a URL that looked very suspicious. Shortly after that ad disappeard Norton had come up and said 3 malicious attacks were blocked. This raised concern because it happened on a secure computer too. Luckily norton stopped the attacks. Could other users confirm whether this is happening to you as well or if it's just me. Please look into this Spotify as this is a security concern not only for me but I assume other users as well.
EDIT!: I have dug into Norton and found the Web Address as well as the IP that tried attacking my computer. The web address blocked is the same as the one that popped up in my Spotify Ad bar at the bottom of the screen. Attached are the details from Norton.
