thanks, it is my machine. why it is on my girlfriend's machine also is beyond me.
I will have to buy an external hard drive, put all my photos videos and important ebooks there, and delete everything else.
I 100% doubt that any ad ware removal program in existence can find the virus.
question, how can the malware be so advanced that it displays fake ads on both chrome, safari, AND firefox???
It could be something that it is intercepting the network requests as a whole and modifying them.
Try it on a smartphone. If the malware ads are still there, try on wifi vs on cellular data.
Try an antivirus like Malwarebytes (it is good because IIRC, it doesn't always run, just when you ask it to scan)
