Hello Lyall and welcome to the BC HijackThis forum. The first thing we need to do is update the operating system on this computer.Your operating system is extremely out of date
. By not keeping the OS updated the computer is vulnerable to every infection on the net and in emails today and trying to repair an unpatched system is virtually impossible. For update purposes, Microsoft has even stopped supporting a system that is this far out of date. Go to the Microsoft Windows XP Service Pack 1.a
site and install Service Pack 1a
Once that is done, go back to the Windows Update site and install all available Critical Updates
but do not install SP2 at this time. This will patch the system with the most current security fixes and plug all the known holes which are present on this system. If you are not on a broadband connection the Service Pack can be obtained from Microsoft for a nominal shipping fee.
After all of the updates have been performed post a new HijackThis log back here using the Add Reply
button and I will review it when it comes in.
