The virus signature database... will begin to download. Be patient this make take some time depending on the speed of your Internet Connection.
I got to the above place in the directions this weekend and had to stop. I have satellite internet and am only allowed so much upload/download per day or it caps me off (slowing me down to dial up speed). They have open download available from 2am-7am everyday and since I work today I had planned on starting the download this am (right now actually). I [i]can[i] download small files without any problems because I know I have a certain amount and typical small downloads don't affect me too much but your wording above made me hesitant that I would reach my cap.
Things do appear to be running smoother and I'm starting to download the virus database now and will try to finish up the instructions after work. Hopefully before the 72hr mark.
