The internet connection freezes PC after minutes of navigation
My PC suddenly freezes when I am connected to the net. I tried to run an anti-virus check
fortunately It didnt show any virus.
At work where I used a LAN connection the problem is absent.
The situation is different at home where I use a wireless connection. The PC freezes after navigating for some minutes. I am unable to do anything. The only is to shut down the pc.
My operative system is Windows 2000. The updated anti-virus I used is AVG.
Any serious suggestion would be welcome.

Are you using vidalia to go out to the internet if so by nature this is a slow connection and may appear or may freeze at times since you are going through several other computers on the tor network.
I would try disabling this and see if you still encounter problems

I would try to remove the start page http://italian.eazel.com/index.php?rvs=hompage completely from the pc
The other entries cann't be removes as I am familar with it.
At the jobside I don't experience the problem. The network is a LAN connection in a domain.
It only happens with wireless connections. I believe anywhere I go it would be the same if the connection is wireless.

I finally resolved the problem by installing the firewall ZoneAlarm.
When a strange request appears after minutes of navigation I block it.
The internet doesn't freeze again. I had installed the firewall Jetico but it never helped. I later on disabled with no positive reults.
I was once advised it's better than ZoneAlarm.
From my experience I think even the free version of it is simply the best.

What is the strange request you are getting ?
Try turning off any firewalls you are using while browsing wirelessly.
You may also have a spyware / malware problem but it sounds more like a driver, card or LSP problem
Try to run LSP fix but make sure all of your windows are closed when you run the software.
http://www.cexx.org/lspfix.htm
other anti malware utilities to try
Download combofix.exe and save it to your desktop
Close any open browsers.
Before starting ComboFix disable and exit any anti-virus software, anti-spyware or any other security related software as they may interfere with ComboFix's operation.
Double click combofix.exe & follow the prompts.
When finished, it shall produce a log for you and display it on your desktop called c:\combofix.txt. By default this log is located on your 'C' drive. Post that log in your next reply along with a fresh HJT log as well
Note:Do not mouseclick combofix's window whilst it's running. That may cause it to stall.
Combofix http://download.bleepingcomputer.com/sUBs/ComboFix.exe
Also go to http://www.tomcoyote.org/hjt download hijack this run it and post the logfile here
