A couple of years ago, a relative kindly gave me an old computer they no longer needed for my son to have in his bedroom.. The idea being it would be helpful for schoolwork, homework and educational things like maths games etc. I agreed on the condition that all the necessary parental controls are in place (to stop son accessing anything inappropriate).
Anyway, all has been ok till this week.
On Friday (totally out of the blue and unsolicited), I had an email from a porn website, thanking me for signing up. Totally wasn't me. Nor do I look at/search for porn. There's only son and I in the house.
I mentioned this email to my partner (who lives elsewhere) and he said it's likely been triggered by something in the viewing/search history. Nothing of that sort on my phone or laptop, so he advised me to check son's search/browse history as it would all be connected and linked to the home broadband. I'm not very knowledgeable about stuff like this tbh, but partner explained how it all works.
Anyway, son is away this weekend so I've taken the chance to look at his history.
Turns out he's been searching thinks like "boobies", "bums" (not too alarming for a curious 9 year old who is learning about puberty at school)... But then he's been searching for other things like "sexy girls photos", "sex" "girl undressing". Then there are some youtube videos in his history about sex-related things, also about intimate hair removal/waxing on girls.
A relative has just taken son's computer away to install tighter settings and will bring it back when done. Also blocked youtube on our smart TV in the living room. No TV in son's room (thankfully).
I don't want to embarass son by saying I know what he's been searching, so I'm planning to say we've been hacked and my bank accounts have been compromised by some dodgy youtube links being clicked on in our house. Keep it general, so not pointing the finger at him.
Planning to say bank fraud team advised me to block youtube to prevent any further hacks affecting us.
Am I handling this well? Any other parents of similar-aged children had this experience?
