I have a Dell Optiplex GX260 PC with P4 1.7 Ghz and 512 RAM.
I cleaned it up today and removed things I seldom use, getting ready to install magicJack on it. I haven't reinstalled Firefox yet, am wanting to keep it as streamlined as I can. I may keep using MSIE 8 or go to Google Chrome or Flock. PC runs better, and I get faster download speed. I installed MSSE but little else, so far. How much more security stuff do I need on top of MSSE? I have good call quality and am hoping to keep it up.

I have two hard drives, one for Win XP and the other for pics, music, etc.
I just tried to re-install some saved programs on spare drive, and it seems to hang up, and I have to use Task Mgr to stop it. What causes this? I get the spinning hourglass and it does nothing. Would another 512 of RAM help out?
Thank you.
