Does anybody know what is this? I contacted hostgator and they are trying to sell me Sitelocker to fix the problem, but want to charge me 1200USD. Actually I do not really trust them, they said that “to keep being hacked the way I am I have an scrip in my website” “, then they said I can fix with their tool, but just after that “if the script keep running I will not be able to fix the issue”. Sorry I am a newbie with wordpress. If anybody can help me I will be grateful. Thanks.
