Malware

[tfmurphhk]

Everytime I go into my site (wp-admin) my Norton tells me I have Malware. It flashes a warning every time I go from one item to another. I do NOT see the Malware warning when I visit the site either on this machine or another one.

The message is fairly similar each time: "Threat found f_00b959" or a similar number.

I have looked at all of my files and see nothing untoward. The Norton error seems to say it's a script error but I can't find anything.

Any suggestions where to look next?
