Hi All,

I am in deep trouble. I feel my website has been hacked. Whenever i am trying to visit on my website as a viewer and as an admin also instead of opening my website it gets redirected to some other pages of ads like hosting , railgun etc.

Can anybody help me that what should i do in this case?

Can i recover my site ?
