hello.... I saw the name "krisbarteo" and "MagicOPromotion" on you forum and that is a hacker infecting thousands of SMF websites with a malicious script which destroys the forum. Please go to the SMF website to read about it. If the user has not infected your forum yet you should delete it.
Here is one link of many about "krisbarteo"
