the part that starts to lag is the part where the users are about to show. I think it says "windows is starting up" or something like that. At that part it takes about 2 minutes for the users to show.
Ouch. Not sure if this is spyware. If you get your computer running, try a defragmentation (go to My Computer, right click on the C drive, select Properties, click the Tools tab, and hit "Defragment Now"). Also, download HijackThis and post a logfile.

You did not get the whole logfile, or if you did, you are infected with an incredibly serious Vundo infection Do another scan, save another logfile, and repost.
