If u r using peer to peer networking based software which use to exchange ur files (MP3 or any other type) then u must be very carefull before downloading them cause ppl are spreading viruses via these software .

When u search for mp3 u will find files written with them extension .mp3 then u just click on it and download it , the point i want to make her is u may not have noticed onething before running the file ( play) look at its extension it may be like this

2 times annel.exe.mp3
u c there is somethig sucpicious, well this is a virus u click on it and nothing will happen infornt of u but its a stealth and polymorphic virus and after few times it will start infecting ur system.

So next time if u download a file carefully check its extension or better scan it first before playing it.
