Well, I have to assume your trying to get those updates while your connected to the internet, sooooo, maybe you have a virus that is stopping you from getting these updates & or getting connected. I would run one or all of the following 'free' online scans to see if the problem gets resolved: A-Squared On Line Trojan Scan -- http://www.windowsecurity.com/trojanscan/
BitDefender On Line Scan -- http://www.bitdefender.com/scan8/ie.html
F-Secure On Line Scan -- http://support.f-secure.com/enu/home/ols.shtml
House Call Anti-Virus http://housecall.trendmicro.com/housecall/start_corp.asp
Kaspersky http://usa.kaspersky.com/services/free-virus-scanner.php
In addition, you really do need some kind of firewall, at the very least the windows firewall needs to be active. Once you think your making progress, I would really reenable "System Restore". If you meet with some success, post back and maybe the other issues can be addressed.
Good luck,
Eddie
I have XP Home. Recently I was having trouble connecting to my ISP, Net Zero(dial up) so I uninstalled the following; Zone Alarm, ADWare, Spybot, and AVG Free antivirus. Now, I can't get Zone Alarm re-installed and when I re-install the others, I can not get connected to any of them to get updates. I get a message saying the connection failed. I received an error message from Spybot while trying to update saying: ''Socket error #1061 Connection refused'' I have ''System Restore'' turned off and also have Windows firewall turned off. I am not having any problems now connecting to the Internet or my email.
How do I fix this?
