Answer 1

Maybe it's some kind of browser extension. They can disguise themselves as useful extensions, but embed their data into the code of other pages.

Answer 2

works in chrome, firefox and opera

Answer 3

1) look in extensions. Extra bang
2) right click on the labels of the browser-properties.
Make sure that the path is, for example, opera.exe , sometimes I see opera.url in my clients in the path and that after the executable there is nothing on the path video and audio, all kinds of media

1) Check what starts via autoruns.exe
2) Check with two or three antiviruses from top detections.
3) Maybe hijackthis will say something useful.
4) Look in hosts
