Powering off the modem is fine. I only suggested that, because there is that brief time before avast finishes installing that you might be vulnerable. Even with sygate set to block all, it may not start before a connection is made.

Yes very similar sytems. 98se serves my purpose very well. But it’s days may be numbered as more and more security programs are dropping it. Avast, though is not one of those. ;D 8) BTW this box does run xp pro very well.
