Chrome writing on it's own?

I may have been hacked. I let my computer idle for a little bit, and all of a sudden, a new tab opened up on Chrome. I think I saw it make itself its primary browser, and then these numbers in the search bar: 110f0a97-2189-45e4-90e9-37c04234fedd, which were input quickly, like a copy and paste. It showed these links. That's when I cut the internet off and did a Windows Malware scan with negative results using the basic software and a full MRT scan.

I use my computer primarily for gaming, and I only go to normal sites (YouTube, Netflix, Gmail, whatever I use to pay my bills). I keep Windows protection on (Antivirus and Firewall). I'm going to download Malwarebytes now and NordVPN for further security.

But has anyone seen this or knows what it is? Thanks.

I have screenshots too, but I can't add them to my post.
