[getopian]

I installed a bad userscript and i removed it. But it continues in Chrome Browser and displays a message the its really annoying. What can i do to fix it? Where are the userscripts are stored and where in chrome i can delete the remainders. And of course i deleted the cache of Chrome but nothing changed! PLEASE HELP ME!!

Try clearing the browser's cache.

I said it before i cleared the browser cache, cookies everything and nothing changed...

It's weird enough that clearing the browser cache isn't helping.
Does the situation also reproduce in incognito mode?
In this case, try to reinstall the browser completely.
