I need support i'm scared!!!!!!!!!!!!

Hello.
Sometimes, we all have those POP UP ads, or : websites (sexual content etc.)
But that's what happened today. A sexual porn web opened.
Now I'm scared.
That my mac is possibly hacked.
Or that someone IS WATCHING ME WHILE I'M CHANGING.

I am super worried. The tabs are troubleshooting and blinking white again and again on Google. This has happened before, and the internet told me it isn't that much of a deal.

But I went onto the photobooth thing (on mac), and it behaved VERY weirdly. You know what happens when someone throws water on an electronic device, the weird green and pink disconfigurated screen pops up?
It WAS EXACTLY LIKE THAT, just for a minute. Then I THINK my webcam blinked green? I don't know, because I wasn't paying attention to it, but I THINK I saw a little green spark!

I am very scared of showing my webcam, so I have stuck something over it.

SECONDLY, I got my pc scanned by the malware website that was already installed into it.
It said there was NO malware or hackers.
CAN I TRUST IT?
Is my pc fine??
Like I said, the white blinking of screens has occured somewhere in the past, but the weird photobooth screen HASN'T.

A word on the whole "website scanning my PC" thing. A website itself cannot scan your PC and any website which claims otherwise is total rubbish.

Judging from OPs comment, they had some antivirus preinstalled, and scanned with that. Normally my money would be on Avast (most common bloatware AV I see) but they mention owning a Mac. I don't know if there's a Mac equivalent of Windows Defender, or if this is a third party AV that's been installed separately, or even if this so called preinstalled AV is part of the problem. But regardless, AV is far from perfect.

I'd wager that this is actually just a mix of OPs paranoia over slightly unusual behaviour and visiting some dodgy site with popup adverts. However these sorts of problems are quite difficult to diagnose, and even more difficult to reliably fix. This is most likely to end in a "scan for malware and keep an eye out for further weird behaviour".

MacOS uses anti-malware XProtect as standard, if you keep it updated it should suffice.
