Using the file manager in cPanel to try to upload today started spitting out this:

Virus Detected; File not Uploaded! (No such file or directory)

All was fine a couple of days ago.

Now I am pretty sure the files I am trying to upload do not contain anything bad because:

First file was a simple html page that I made with a text editor and contained no scripts or anything
Second file was a jpeg that I made myself
I am working on a Mac
My anti-virus software (ClamXav) is up to date and cannot find anything

After trying with file manager a couple of times I just used ftp to upload the files.

Does anybody know what might be causing this?
