@sgunhouse So after the adware scan I did another scan with a different programm and noticed that a specific site would always have background activity when reloading my browser. I then inquired about this and got it fixed with the uBlock extention and a specific block import for it. Now the background activity is no more.

This sadly does not explain why the spam sites randomly opened yesterday, scince the site today only had activity in the background. Scince multiple malware scans didn't find anything besides this, I would still say it was the problem

@sgunhouse Adware scan sadly didn't find anything

Hey, so I was just browsing, when out of nowhere 10 or so mega Spammy websites obened each in their own Opera instance. I of course assumed I had somehow gotten a virus, and scanned my PC, but it didn't find any threats (still doing a full scan right now). When a friend contacted me that he had the same thing happen to him just a few minutes after myself. Is this an issue on Operas side maybe? Me and my friend are usally pretty careful about malicious content and it's weird that we both got it. I also noticed that before this, a screen of mine bugged out for like 2 seconds and that My PC removed a trojan from my OperaGX folder a few days earlier. I really don't know which could have caused this as I have a popupblocker and I reguarly scan my device and dowloaded content.

The full scan my friend did as well as the offline scan returned nothing.

Could this be a malfintion of the pop up blocker extention failing and letting pop ups through that it blocked before all at once?
Is it an Opera wide Issue?

Any tips are appriciated
