Compression does wonders Even the most basic one can cut the size of such info transfer for over 50% without affecting CPU usage. @pbust I've also had random problems with Quick scan staying at 0% on my sister's laptop. Once it was stuck at 0% and next time it was working. Then it was stuck again and next time it worked again. Without any real patter, it looked random to me. She's using Windows Vista Home Premium 32bit.
