Hi I have a client's computer infected with a browser popup ad wich pops up on every new webpage opened. I'm quite adept at removing infections, but this one has got me stumped. So far I've run a Malwarebytes full scan which found nothing. I've also done the same with SuperAntiSpyare, Hitman Pro, ADWCleaner, JRT, Avast Rootkit Scanner.. all scans come up clean. I've run HijackThis as well, which shows no suspicious entries.... So I'm hoping someone here will recognise this particular popup format as now I'm stuck... Please see attached screenshot. tks roger
