virus signature updates

Hi Guys....

I just got the latest ClamAV portable app. and it is once again taking forever to get the virus signature updates - this happened the last time I got the program.

I'm using dsl lite with a 768kbps down speed, have used more than 5 hours and it still isn't done? My connection is just about the speed it's rated for!

Anyone have any ideas why? Thanx beforehand in case ya do ! :-)®
