Virus warning
 

G'day. I have made a search of the forums, however I can find no reference to the below mentioned item. So it appears that I have to be the idiot who posts this warning for what it is worth.
Over the past couple of days I have found files (.mp3's) which contain a virus. These files disguise them as legitimate audio files in that they have the format : (Name of legitimate artist - Name of legitimate song). These files are 5611Kb in size. They do not contain any audio information. I have found that if a file of this size is downloaded and then another files is attempted to be downloaded, of a different name, a popup appears indicating that one has already downloaded this file under the name of the previous download. This file was submitted to virustotal.com with the following results :

I have attempted to block the various hosts without much success however I have been able to maintain the 'Junk' filter in respect to these files. Anyway I have submitted this post in the event that somebody out there may be interested. Regards.
