Hi! I never claimed to be a trained malware expert! There's a lot I don't know about these things. I don't know if Chrome gets modified by malware easier than Firefox. I just know that it was corrupted on a seniors PC. I removed it. The senior said there was a pop up to down load Adobe and she clicked on it and that's when all her problems started. I didn't give her a lie detector test.
This is a link from our forum, I haven't seen this pop-up but it may very well be what my senior clicked on.
I don't wish to argue any more. The below link is by our owner and leader
@Jack Does this attack Chrome more that Firefox? Is Chrome more vulnerable than Firefox? I don't know. That's up to you experts. It sure is taking a lot of our malware fighters time
