My site was infected with myfilestore malware. I found malicious code in "Display Don't Auto Convert Option" plugin and removed it. After some time forum start to redirect to myfilestore. I disabled any product i.e. "Auto Check Remember Me & Rules Boxes" or etc, forum didn't redirect. whether product is enable or disable. But after some days forum again start to redirect to myfilestore.

First I suggest you change passwords on everything from the cPanel or Plex Panel to the vBulletin administrators (all of them).

Make sure you don't have any new admin accounts you didn't create.

Replace your .htaccess file with the one from the upload folder.

Upgrade to version 4.2.5 from version 4.2.2.

Check for suspect file versions. Delete any suspect files.

Start with those steps.
