Virus stuff - I use Microsoft Security Essentials, and my computer pretty much
sucks for a few minutes at boot-up, after that MSE doesn't seem to get in the way.
I think "real time protection" is important, so I wouldn't turn off any of the recommended
settings...
This thread has convinced me to call ATT, though... I have the most inexpensive
kind of DSL... the ATT speed test shows .66 mbs download and .1

mbs upload... I don't think
it is supposed to be THAT slow... I rented a movie from iTunes once, it took eight hours to
download...
