Well I have told my girl not to download or click shit from people on Facebook and she did anyways. She downloaded some extension on Firefox offered by some link on Facebook for profile themes and shit. So as soon as she installed and selected a theme she got ads all over her FB page and Firefox turns to a red screen and says there are security threats.
It found trojans and all kinds of trackers and shit.
I ran Malwarebytes and it found some stuff and I got rid of it. I got rid of her extension on FF but it's still doing the same thing.
On her FB there are still ads on it that are not on my own FB when I am on the laptop. She did all of this on the desktop.
So how do I get rid of this shit?
