hi, there maybe something wrong with your IE.



firefox is much smaller than IE, so i run faster than IE.



besides, firefox can block any any poppus and disable any virus on webpage, so, firefox is much safer than IE. as you know, most of the virus is spread throught internet and webpage.



download firefox for free:

nasty little bugger this one - sticks it self in to the windows registry and changes the DNS ip address that is why you can not get a IP address



if you are comfortable with the windows registry - click run then type regedit



now navigate to



HKLM

\SYSTEM

\ControlSet001

\Services

\Tcpip

\Parameters

\Interfaces



in the right hand pane look for the trojan name or value and delete



then click file and exit



now restart



hope this helps



Oh you may have to reset your IP address as well



afterwards click run then type cmd



type ipconfig /release



then



ipconfig /renew





PPS



OK need to go back into the windows registry and navigate to the same location look for any of these values in the right hand pane





OH and make sure INTERFACES is highlighed look for



[Trojan.]Win32.DNSChanger.p (Kaspersky); [Trojan.]Flush.D (Sophos); [Win32.]Netmesser.J; [Win32.]Netmesser Family; [Trojan.]Win32.DNSChanger.k (Kaspersky); [Troj/]DNSBust-A (Sophos); [Trojan.]Win32.DNSChanger.m (Kaspersky); [Win32.]Netmesser.I; [Win32/]Netmesser.I!Trojan; [Trojan.]Win32.DNSChanger.f (Kaspersky); [Win32/]Netmesser.A!Trojan; [Win32.]Netmesser.C; [Win32/]Netmesser.D!Trojan; [Win32.]Netmesser.F; [Trojan.]Win32.DNSChanger.d (Kaspersky); [Win32.]Netmesser.D; [Win32.]Netmesser.A; [Trojan.]Flush.A (Symantec); [Win32/]Netmesser.C!Trojan; [ ]SpoofDNS (McAfee); [Trojan.]Win32.DNSChanger.e (Kaspersky); [Win32.]Netmesser.H; [Trojan.]Flush.B (Symantec); [Win32/]Netmesser.H!Trojan; [Trojan.]Win32.DNSChanger.h (Kaspersky); [AdClicker-]BM (McAfee); [Troj/]DNSBust-B (Sophos); [TROJ_]NETMESS.A (Trend); [Win32/]Netmesser.B!Trojan; [Win32.]Netmesser.B; [Win32.]Netmesser.E; [Trojan.]Win32.DNSChanger.a (Kaspersky); [Win32/]DNSChanger.9825!Trojan; [Trojan.]Win32.DNSChanger.g (Kaspersky); [Win32/]DNSChanger.9725!Trojan; [Win32.]Netmesser.G; [Win32.]Netmesser.K;



or any similar - these buggers take many forms



just make sure that no of these are still in the windows registry



no back to your network problem



right click on my computer and the properties - then hardware - then device manager - then click on the plus next to network cards > right click on you network card the click on uninstall



now restart



then go back to run then type cmd



type ipconfig



what does it say (you may have to email me with the result as Im off to my bed soon - so i won't be able to answer tonight)



if it comes back with a ip address and defauolt gateway



ping each of these



type ping then the ip address - do you get a reply



also



ping 127.0.0.1



if you do not get a replay then it has screwed your tcp/ip settings and the winsock



try this



netsh winsock reset - only if you have got win xp service pack 2
