Pranaams, Wondering why.
I would go even further n say 2000kbs, What real song is less than two min's
unless they are a crap bit-rate, n whats the use of a track that sounds like its
being played from a transistor radio under water
MP3 files cannot be converted to .EXE its not possible, They are being Deleted, Then replaced with (Who knows what) with an .EXE extension
It may be a zip/rar file with multiple files inside, e.g. worm,trojan & virus
combined.
I believe its a new threat, not an existing one & a bad one at that.
My addvice move your shared folder n rename it, till a threat signture can be put on it, and backup shared folder to exturnal drive. if thats not an option
then back it up to a password zip folder.
On last count I had 21,500 files & all are very dear to me. I would Die if I lost
my collection.
Peace.
