I dont directly connect to the Internet on the machine, i connect using a wireless gateway. In terms of firewall i aint currently been using one (stupid i know). Was going to install Zone alarm, not a computer tech person myself.

I've been told by windows update there is 1 security update that i can download, i try and download it and all i get is an error on the page saying could not be installed.

I tried to do a system restore, it gets to the point where it reboots gets me back into XP and the window says restore unsuccessful and doesnt carry out the restore.
