<![CDATA[Malicious code hidden in the <head> label]]>Hello.
So the day before yesterday I was inspecting a basic page to see how it was made, I was looking at the head section when I realized there was a label called "style type=text/css" :

style.png

I opened it and this what was inside:

root.png

pag.png

It includes a lot of links to many kinds of websites, most of those being adult pages.

This label is included in every page I go, also, I have my Opera account linked with my notebook and my other PC, so it happens on the two devices. A friend of mine who also uses Opera has the same exact problem.
Also, if this helps you, I was looking at the console at some point and it showed me that the AdBlocker blocked a site called "Static Hotjar . com" from redirecting me to another pages.
I wonder if this has a name and if it has a solution, I've already uninstalled and installed Opera again but it didn't work.
Thanks.

@jorovats it's CSS, it tells the browser how to display content from that site - in this particular case, to hide it. That is the ad blocker hiding ads from those sites, not actual links to any of those sites.

Like sgunhouse said, it is code injected by Opera Adblocker to hide ads.

and if it has a solution,

You can disable Opera Adblocker, likely you will get rid of this stylesheet then also.

Oooh I see, thanks for helping me, I learned something new 👍
Best regards.
