I helped a friend build this site for their university about 6 months ago: muls.org
Since it was launched, I haven't touched it, I've just let my friend edit and change the site as required. A few days ago I received an email from my friend saying that visitors to the site are getting malware warnings.
I've had a look and it seems as though iFrames for phrae.tv had found their way to the header.php file. I since deleted these, but the problem is still occurring.
Has the site been hacked??
How can I fix the site and remove the malware?
