Internet Speed is so so so so so low!!!?

Two days ago my internet speed was flying! I downloaded whole albums off the internet in minutes! Now it takes 5 hours to download ONE 3.5 mb Song! and the speed is 160 BYTES(!)per SECOND!!! Its not a connection problem the provider says because the speedmeter shows really hi speeds! I ran a virus and antispyware check with Kaspersky, Super Antispyware, Panda and NOD32 3 TIMES! and nothing was found. Also i dont think its a jam coz my area and my country generally hasnt so much internet traffic and this is the 1st time anyway. I repaired the connection, restarted it, restarted the PC but still the same. Any ideas??10 WHOLE POINTS TO THE ONE WHO SOLVES IT! thnx
=:)
It supports up to 2 mbps
Its not from limewire or utorrent or anything like that. Its from direct download files like emp3world mp3raid and sites like that.
THANK YOU ALL!!!! I SOLVED IT!!!!!
