prestashop 1.6 hacked

[smog20]

Hi Dear,

I got hacked and they published a sitemap with 8000 urls in state of arround 200. (most of them give an error that doen't exist)

I erase the sitemap hacked and resend the correct one.

But I still see url in Jaopanes in the google SERP. It seems to be the Japanese keyword hack

 

Furthermore I saw a sm_tunnel_s31Kkksy.php file which seem not to be part of the original prestahop site.

 

Anyone  have a clue how to fix that Hack en recover my site with original description and titles?

 

Any help would be more thant welcome.

 

Thanks in advance

 

 

Laurent
