I was just on the internet on reputable sites, when there was a little computer notification popup that came up. It looked like the red stop sign one, but it disappeared quickly before I ever read it. Shortly, after that chrome froze up (I know! chrome is terrible). Included is a picture of the red stop sign notification, in case you don't know what I'm talking about; I found it online, so the content of the message on the screenshot is not relevant to me. Basically, should I be concerned? I don't know what the message even said.
