How to restore network and LAN configuration after virus infection?

Hello,

Some times I have got any computer thatīs infected by some virus and internet is not working. Booting Linux, Internet is working, but in Windows it is not. I am sure itīs virus problem, because IP, and others adjust are OK. Sometimes after scanning Windows with some antivirus system, internet works, but sometimes it doesnot.
Well, is there any way to restore and repair damage caused by some virus or windows crushed, that are affected Internet? Now I have a computer that only things is affected is internet conexion. It doesnot work.

I repeate, is not a problem with LAN card, IP adress, so on...

Wait for ideas to check and try.

Get rid of the virus. Best way is to Wipe the drive and Reinstall Windows.

Yeah, I removed the virus, but this virus has changed something inthe configuraiton of Windows. I am sure there is some way to chech and fix this configuration but I dont know how to do it.
There is some command in CMD or some bat file to can fix that?

Try flushing the DNS cache and restoring MS's Hosts file:

Copy and paste these lines in Note pad--->

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0


Save as flush.bat to your desktop.
Double click on the flush.bat file to run it.Vista and Windows 7... right click the .bat file and choose to run as Administrator. Your computer will reboot itself.

Hello Jacee

That is right what I was looking for. I will try it and tell you if that works for me.
But is that only for Windows vista and 7?
Can I do it for XP?

You can use that Batch file on XP too.

I will test that. If that doesnot work, next step is clean reinstall of windows or there is something more that I can do?
