I also had this issue when uninstalling immunet from my Win XP sp2 laptop using windows uninstaller.
1. c:\windows\system32\config\service was corrupted during the uninstall and on boot machine came to the BLUE Screen of Death
2. my user profile was also corrupted.
It was a pain to fix this problem, however here's what I did to get my laptop close to where it was before Immunet was installed on my machine.
1: Boot into recovery console.
2: follow instructions in this Microsoft support page
http://support.microsoft.com/kb/307545
3: reboot machine
# If your user account was corrupted follow the instructions in this Microsoft support page.
# If you want your user directory profile in C:\Documents and Settings be the same as your login username follow this instruction and omit the create user instructions in the Microsoft support instructions.
1: Login as administrator
2: rename C:\Documents and Settings\username to something else
3: go to users/groups in computer management and rename the user account to what you just renamed the users directory to.
4: create a new account with the username your old account was named.
5: logout as administrator and login as the new user you just created.
6: logout of the new account and back into the administrator account, the system should have created a new directory in C:\Documents and Settings
that is the same name as the new user you created.
7: Follow the instruction on copying files from your old user directory to your new user directory outlined in this Microsoft support page.

This is the steps I used to fix my laptop and hope this helps anyone that ran into the same issue.
I'm not writer, so if anybody wants to clean my instruction up so a novice user can understand them, please do.
