I was facing the same issue. In my case, the culprit was Page Ruler extension. I've removed it from my browser, and also reported it as abuse to Google.

At the moment, it seems it's been already removed from Chrome store. It's URL - https://chrome.google.com/webstore/detail/jlpkojjdgbllmedoapgfodplfhcbnbpn - is not working anymore!

This is likely caused by an extension. Even if you haven't installed any new ones, an update to one of your existing extensions may have been bundled with some malware, perhaps inadvertently or perhaps not.

Try disabling all extensions, and if the problem goes away, re-enable them one by one to see which is the culprit.

As also mentioned in the spanish thread, the 'Page Ruler' extension was for me the culprit. Deleting it fixed the problem immediately.
