While trying to upload .swf files to the server , the following cPanel message appeared :
cpanel Virus Detected; File not Uploaded! (No such file or directory)
Scanning the file with Anti-Virus said that it is clean.
Clamav might be causing the problem.
If you have root access to the server and are sure that the files are clean then do the following :
WHM > cPanel > Mange Plugins > uninstall clamavconnector
This should fix the issue!
