"so you Download Music Files without Anti-Virus protection? "
Like Timlub, I do not have anti-virus on my player PC. So, I simply download files using a PC that does have virus protection then move the files across my network to the appropriate location. Not really that hard. Of course, most of my music is from my own CDs, so anti-virus software is not an issue. The idea, as Elizabeth and Timlub have said, is to minimize unnecessary software running on the system. It can make a big difference.
