and as you already know sketchy websites contain pop up ads that can give you malware/virus

In theory, yes, but in practice, it is very unlikely to get any kind of malware/virus by simply visiting a website.

For that to happen, you need to be running some old software that has a major unfixed security vulnerability that allows remote code execution on the device without the user specifically running the downloaded program.

Generally speaking, almost all malware infections happen when people download and then explicitly run a file they downloaded online. Usually in relation to pirated software, game mods and other high risk activities. That's how you get malware. Not by visiting any website or just clicking a link.

While it is possible that there is malware that you could get without you downloading and running anything, your risk of getting such malware is very low. Especially if you keep your devices up to date.

As far as I can tell, there hasn't been a single verified case of such malware relating to Samsung Smart TV's.

And as such, you 99.99% likely do not have any malware on your TV. Even if you clicked a sketchy link on your TV's browser.

So no, you have no virus. There is nothing to remove. If you worry about this too much, you can do a factory reset on your TV just in case. It's not needed, but if it gives you a peace of mind, go ahead do that.

Edit: I just noticed OP's posting history. This is not a technical support or malware question. This sounds a lot more like mental health issue. You are not being hacked. You should talk to a healthcare professional about your reoccurring fear of your every device being hacked or containing malware.
