Obsessive fear(POCD)



I have a fear that an old android tablet that I used to look at porn with has illegal images on it

For context, I suffer from POCD and OCD. I’m trying to get the tablet working but it may not work. I have no idea how hard it is to actually find that type of stuff, I’ve just heard horror stories of CP being on popular websites. And there were a lot of times where I would mid click on a porn ad or be directed somewhere else or have a pop up ad. So what if they somehow downloaded something in the background? Or maybe I’m misremembering me actually visiting a weird website I’m scared of destroying it because what if I don’t destroy it well enough and they trace something back to me if something actually is on there.

What should I do? How can I get rid of the this fear? For context I used to only masturbate to furry/cartoon stuff.
