His account was probably given full administrator privileges and his wifes account limited privileges.
Therefore try changing his wife account to admin - look in :- control panel/user accounts/change an account/USER NAME/change account type then tick administrator
If this doesn't work enter the account in safe mode and run msconfig and stop all tasks in the startup folder from loading - then reboot - if this solve the problem its a program loading that is causing the problem.
One other thing look in the "event viewer" located in admin tools and see if you can find an error message.
By-the-way why did you replace Norton AV - if you like I can show you how to download and install the definitions without using live update.
A friend was having trouble with getting kicked off the internet - after a few minutes surfing a box popped up telling him his computer was about to be shutdown. This sounded like classic worm/virus stuff so I ran McAfee Stinger and it picked up about 3 worms (unfortunately I didn't note the names) and cleaned them. I then uninstalled his Norton AV as it was out-of-date and replaced it with NOD32. This is where the problems started...
When his laptop (running WinXP - not sure of the specs as I don't have it in front of me, suffice it to say that, apart from surfing problems, everything worked fine before) loads up he has two logins to choose from (his and his wifes). His login when clicked loads up XP no probs, but if you choose his wifes login it loads upto the desktop, and then won't let you do anything (e.g. open ANY programs), and also if you let the cursor hover on the toolbar it gives the familiar eggtimer, but nothing is loading.
I have uninstalled NOD32 but the same problem occurs.
Is there an diagnostic programs that can be used to see why the computer freezes on his wifes login? Or does any of you ultra-clever people have an inkling as to what the problem could be?
Thanking you in advance
