I resotred my website and deleted all malicious code, but i still see this trash in when i do site:mywebsite.com. I don't know how hackers do this, how it possible to put these pages instantly to google results. I can't index my content to google through Instant index API or Google Index API, but they did it for like 1-2 hours while my website was hacked. These pages don't even exist on my website.
So who knows what should i do with it, and how can it affect my website?
