Cześć,
That is for the qualified removal expert (essexboy) to be established. What I gave you is extended protection, so that after this has been cleansed you won’t give in(out) inlog data from your google account onto sites that cannot be trusted (phishing sites etc.).
It is probably where the malware came through. Essexboy stating that Google Chrome is very popular so sought out specially for attack and it has present issues.
Ok agree with you fully, cleanse that malcode off first with the help of a qualified removal expert here (essexboy), then install that extension that was specially launched by Google to-day. That they did so is proof of the fact that you aren’t the only victim of such not-secure connections. If youlike to discontinue Google Chrome, try Sleipnir6 browser, it takes all your chrome settings and extensions and does not have the Google Chrome compromittal issues. 
I run Google Chrome exclusively inside sandboxie, export my settings/bookmarks. Clean the sandbox every 5 days and the regular Google Chrome browser get cleansed with a CCleaner wipe every week as well. I can state I have very little problems so far (also thanks to Avast’s shields and PUP-mode).
Wszystkiego dobrego,
polonus
