Turns out, google webmaster has tools to check to see if your website is clean after being hacked. It call “Hacked Sites Troubleshooter”, you’ll be going through the trouble shooter step by step to see if your is ready for being reindexed again on google search engine.
After the “Hacked Sites Troubleshooter” completed, I can submit “Request for review” but Google said it will take sometime. Maybe a week, a month, I don’t know. Will see.
I guess I learned the hard way. I should have harden my web server security, should have update my antivirus ensure it’s working properly and real time proactively.
