How to Clean up a Hacked site? My site is deindexed.

My site is deindexed, and I believe a hack is to blame

[keyblast]

Hello all:

I have a number of websites spread out across a couple of different hosting accounts (bluehost and hostgator). This morning I woke up to find quite a large number of my websites have been deindexed from Google. Some of these sites are a couple of years old and I have not changed anything on them for a while; and I believe everything is in compliance with Google's webmaster guidelines.

Also, all of my hostgator websites are fine (still indexed); which leads me to believe that somehow my bluehost account was hacked (keylogger perhaps?) and these sites were compromised.

So, my main question is: How do I find out what was done to my sites? I have been trying to find hidden links, etc; but this is not really my expertise. What do you recommend to find out if my sites have been hacked and what has been done?

Is there a service I can use to clean up my sites? Thanks!

Hi keyblast, first of all Welcome to WebmasterWorld!

Sorry to hear that a number of your sites have been deindexed. If you think that hacking your sites has caused this, your first step should be to logon to Google Webmasters Tools. If Google detected anything suspicious with your sites, there may be a warning visible there.

If you have a dev machine and original content run a comparison on files and make notes of any changes on the host server. That will isolate anything unusual.

Bear in mind that some things get deindexed because Google changes the rules and does not tell anyone in advance. What was perfectly fine a year ago may not be okay today...
