No access to network/internet for programs except IE on Win XP

[Ales]

Hi

My system specs: Win XP Home with SP1.

I am having problems connecting to the internet from programs such as
msn messenger, mozilla firefox,various ftp programs and updates.

Only IE (6.0) and WindowsUpdate are the programs with internet access.
When I try to ping on any IP address (except 127.0.0.1), I am getting
the error 65:
"PING: transmit failed, error code 65."

At the time this problem started:

1. the computer had quite a few viruses on it (like
DerBiz/Trojan.Win32.Dialer.gp).

2. we tried to install SP2, but it caused problems with ZoneAlarm and
system became very slow. So we uninstalled it.

So far, I uninstalled ZoneAlarm, switched off firewalls, checked
against viruses and spyware, and did system restore. No luck.

Many thanks in advance!

Ales

The spyware may have damaged your winsock, or dns.

the netsh command in SP2 can rebuild your Winsock. Open the command prompt and type: netsh winsock reset , then press ENTER.
