I have some pretty invasive adware going on right now. It is in both Safari and Chrome, so I don't believe it is an extension (I have also looked through all extensions). I have also tried searching for all the recommended adware agents found on the Apple Support Forum (https://support.apple.com/en-us/HT203987). I have also looked at recent downloads and I can't find anything suspicious.
I am wondering if anyone can recommend some safe software to target the adware.
