We had a problem on the server yesterday morning whereby a script was run on the server appending a trojan Iframe script link into some of our .jpg files. The problem has been fixed and all affected files updated. The trojan was unable to be detected my most anti-virus software - but here is a link to the antivirus tools that we're able to pick it up. http://www.virustotal.com/analisis/b56098ec067ba43ad3144b94c2d99239
The server guys are currently running a Security Audit on all affected systems to ensure this is not repeated.
If you however experience any problems, this would be because of cached files (either on your local machine or Telkom SAIX) – the best thing to do is to clear your cache & cookies.
If the warnings persist then please send me a mail at email@example.com
with a screen shot & I will follow it up.
