Unwanted gambling advertisements

Hello, I wonder if anyone else has been receiving - from Ladbrokes & Titan - web pages that keep popping up: not minor ones on an open web page, but a full, stand alone page
I repeatedly got an up-to-date Ladbrokes page - exhorting me to gamble, in some way, with them.
Never been a gambler, never knowingly clicked on possibly related links on that subject at all.
I emailed Ladbrokes, and got a pleasant reply from them, saying their tech department would look into it. It seems that they must have, because I no longer have my browser (Firefox) hijacked by their ads - I have, however, now got a regular appearance from "Titan gambling" in place of the Ladbrokes' one.
Don't believe in conspiracy theories, but a little too coincidental for me.......
I've emailed Titan, so perhaps they'll disappear soon - only perhaps to be replaced by another gambling concern!
Anyone have any thoughts/experiences of similar?
Cheers, Les.

Is it worth a bet on which one it will be?

D'oh!

I get that sort of thing occasionally, along with pop-unders. Usually I just dismiss them, but if one gets annoying I add its domain to my hosts file, directed to 127.0.0.1.

I use a Mac, so next time anything tries to load the offending site the built-in web server (Apache) just spits back a 404, which still has to be dismissed but is less annoying and means the offending site doesn't register any more hits (from me anyway).

Not sure what would happen on Windows.

Run a scan on your PC from Malwarebytes for example to rule out any nasties on your PC.

Use a firefox based browser and install Adblock Plus and pop up blocker. End of problem.

Try AdwCleaner

Hi Ian,
First thing I did - along with a full SUPERAntiSpyware: alas no joy. Seems a little weird though, that one nasty should immediately be replaced by another after 1st said nasty left!
Cheers, anyway, Les
ps, I also ran a full Avast scan, too.

Hello prof,
I do run FF and Adblocker - always have.

Thanks for the advice, ecky.
I've used that before - I think I got it from Bleeping Computers, along with ComboFix.
No joy I'm afraid!
Cheers, Les.
