where is this code in wp db?

I ran a security check on one of my wp sites and this came back..
The 'blog_charset' option in your database is set to 'UTF-7' which indicates your site may have been hacked. If hackers can gain access to your database via phpMyAdmin for example, they will change this value in order to inject malicious code into other parts of your site or allow XSS attacks. The 'badi' hack does this.
where can i find this and what should UTF-7 be chnaged back too?

 

Hi my friend, Try this

If you have access to phpMyadmin > go to your database, find the wp_options table and click on Browse to find the blog_charset table (row). Click on the "pencil" for edit and type in "UTF-8" (without quotes). At the bottom of the page click "Go".

 

Thanks for the help!
