Before 2 days I found inside the httpdocc a new folder which name was css. Inside this folder I found a file named sys0972500-1.php , which it caused send thousands spam emails from my server.
I deleted it and today I had the same problem.
What moves should for prevent this?
The website I have inside the httpdocs is joomla, which I have updated to the newest version and also I updated the templates.
I also changed the ftp password.
I found on the net another guy with the same problem but he didn't find a solution.
You can find the code which was inside the suspicious file by clicking the link : http://pastebin.com/NbyT5wfF
Thank you in advance
