If it is on all, you could try another Router/Modem but I haven't had any inject ads into my browsing sessions in the past, nor have I heard of any that can be infected in this way. I could be wrong though and am interested to hear if that is in fact the case.
I mean it's the only thing I can think of. Because this whole malware pop up crap all started after our internet provider upgraded our modem to a new and "better" one, but after we upgraded a little bit later this all started to happen. I was going to try and switch back to the old one but I can't find it and I think my dad turned it in once he upgraded. So I think I'm sol at this point. However, I am doing that boot scan right now so hopefully that does the trick, because I am all out of ideas except buying a new modem...
This is a longshot and unlikely, but I have heard of a type of malware that can infect a computer and change the DNS settings of a router in order to inject ads to make revenue. Hackers can also hack your router manually, made even easier if you have never changed the default password. Malware at some point is the much more likely of the two but again, even this is probably unlikely. You could log into your router by typing your gateway ip into a browser (usually 192.168.0.1) and if your router has this option, view your DNS settings, you could then contact your ISP and ask them to confirm these settings to rule this out. Again, this is a longshot but it may be worth checking out.
