When trying to sign into windows XP it begins loading and then says closing network connections almost immediately, same thing happens in safe mode. Also, can't log on as administrator and leaving the password blank. Please help! I'm pretty sure this is all virus related...My Antivirus software had expired and I never renewed so one day it just shutdown....

napp402, suspect you're correct. If you've been on the net unprotected, you can pretty much bet on it. First thing you need to do is clean your machine. I'd scan for a virus and a Trojan. Be aware that a virus and a Trojan are similar, but not the same. Many times, an AV detects one it can't clean, other times, it gets missed entirely. If you need to clean one, Superantispyware can do the job and you can get it free @: http://www.superantispyware.com/ among other places. They have a Vista compatible version if needed. If it turns out that you need to use it, be sure to update prior to running and disable 'restore' (restart after cleaning) so it doesn't get put back. They just released a new update recently and it changes all the time. Things are in a constant state of flux. Then, you need an antivirus proggie. There're several free ones around. I use and recommend Avast! Get it free @: http://www.avast.com/avad1.htm HTH. Ed in Texas.

I have what appears to be an identical problem with my son's computer. My question then is how do you run an anitvirus program if you can't get into Windows in the first place?

I have the same problem in two computers runing Windows Media Center, they used to log on by them self, now I have the log on screen as waiting for me to type the password , anyway I press Ok, and after that it shows "Loading personal settings", then another screen "Logging off" and another one with "Saving your settings" message, then it takes me back to the log on screen. Answering to CobraJack, the only way I know you can run the Antivirus its setting up that hard drive as slave in another computer or you can use one of those USB devices so you dont have to open the PC, and of course you need another PC with Antivirus, Any way, I did ran the antivirus, actually two of 'em (AVG and Symantec Endpoint 11) and they detected some viruses but still when I connect the HD back to the PC still does the same. Does some body out there knows how to solve this problem? Thanks.
