Since this morning strange advertisement is appearing on top of many pages I open in webbrowser (see screenshot at the end). It's happening in any browser (tested FF, IE and Chrome), on any of three machines in our household, even on iPhone (no matter if connected on Wi-Fi or cellular network [not true in the end, see my answer]). Even on Debian system run in VMWare.
Sometimes the ads do not appear in Firefox, but appear in IE. Sometimes they do not appear on iPhone when connected on cellular, but appear when connected on Wi-Fi. But mostly they appear in any case. On some pages the issue corrupts a page rendering.
The advertisement is identical in every case. The same tree banners, except for Amazon banner changing the product. On iPhone the Amazon banner does not load. On some pages the set of ads repeat two or more times.
Some of the pages the problem is happening with:
- superuser.com (any SE site)
- ask.com (ads appear twice)
Not happening on:
(though the lists can be affected by random component of the problem).
The ads are rendered by HTML code injected just after an opening
I do not have any unwanted plugins in the browser(s). Nor I identified any adware/malware on my machine(s). I didn't even expect that, as the problem occurs on iPhone too.
Does anyone have any idea, why this is happening?
