Began browsing these forums for past six weeks now and am impressed by the amount of great info, great support and great members!! I am not very computer literate, and I have several questions to ask.(One at a time, though). First of all, my PC is WinXP SP1.(All patches up-to-date + NAV def.) Downloaded SpywareBlaster 3 weeks: and SpywareGuard a week later. Q. When performing a Defrag. on my hard drive, is it necessary to close down (exit) Spywareguard prior to defragging? Also SpywareBlaster? The reason I ask is that 2 days ago when I defragged in the usual manner, e.g.: disconnected cable modem->disk cleanup and disabled ICF. I rebooted and when I logged on, I had no internet. (I finally got it back about an hour). Thank for any help you can give.
