I started having this problem a couple of days ago; at first I was seeing the same colexity/espeak URL’s that others were reporting but today there’s a different, larger batch. MWB is apparently finding the problem but not fixing it. Avast scans turned up a couple of false positives. One thing I noticed before the popups started was a bunch of weird redirects in Google searches and ‘connection was reset’ pages. Once those cleared up the popups started. FWIW, I have an XP machine on the same network that doesn’t appear to be affected; one difference is that machine is rarely use for browsing. Thanks for the help!
could you also attach AdwCleaner and aswMBR logs…see the guide
