Dangerous Site Warning

[Dahliasrule]

Was just reading an innocuous thread when a red warning flashed up saying that the site was dangerous and that said site was asking me to do something dangerous. Disappeared quickly but as I read further posters it happened again so I came off Mumsnet for a moment. Has anyone else had this?

@Dahliasrule i had the same thing happen numerous times yesterday. It was supposedly for Norton security and had a countdown timer on?? I've attached the image but it might take a while to loade

Just got the same.

Yes I just got the same. It flashed on and off so quickly, I couldn’t manage to get a screenshot but it said the same as @Dahliasrule. It was a red screen with the message

Yes i got this once yesterday. The same as @shellyleppard except it was Macafee.
Gave me a real fright .I did a scan on my phone after it happened because it was worrying.

I got this too

This has been happening for 2/3 weeks now. There is another thread

I’ve had it happen twice

Same thing happening to me

First time for me. I'll report it to the admin team

Yes, other threads in it. Being looked into, but only by deleting submitted URL's 🙇🏻‍♀️

I saw this on the other thread but my screen was different. It was totally red. Flashed up dangerous site and something about the site wanting me to do something dangerous.
