Try right clicking them and select delete or undo installation.
Then rescan for new devices.

Hope that helps.

You will need to know the manufacturer of the NIC card,  and download the drivers from either the card manufacturer, or the manufacturer of the system.

You may need to update the chipset software on the system to reload the USB or PS3 base systems.  This will also be on the Manufacturer of the systems website.

Can you tell me what manufacturer of the system?

HP is the manufacturer of the system. Nvidia is the manufacturer for the NIC.

If they have been installed before, the inf files and other nescecary files are most likely still present on the system.
Rescanning for devices after deleting them should automaticly find and install the drivers again.

I agree with Master, but if your infection was this bad, you may find that it was able to 'infect' your system files.  i would remove them and start from the beginning.  

I may look into running the SetupCD's from HP to repair your entire Windows installation.

Shoot me the Serial number and I will help you with links to the drivers you could use.

cheers!

That was the first thing i tried. But when i try to uninstall the Nic. it tells me it cannot do that  because it maybe necesary device to start windows,,,, but i will try it again. I have tried installing and uninstalling the PS2 keyboard and samething happens after  installing. Also, i just went out to get a USB keyboard and samething is happeneing to that keyboard.

When i try to update driver on the Nic card it tells me it is the same driver and it doesn't need to be reinstalled.

ouch, that indeed sounds like some of the system files are damaged.
I would suggest to backup as much as possible and do a fresh install after being infected that bad.

You can also try to use sfc /scannow
sfc is the windows XP System File Checker
The program will see and repairs corrupted system files (most likely keyboard.sys too)
You will proberbly need the windows XP CD

Okay, when you boot to safe mode, do you still have problems with the keyboard? how about the nic when booting to safe mode with network support? Sounds to me like you should be able to do a system restore to a time prior to the infection. This does not bring you deleted files back but does repair the registry.

Try this to fix the keyboard.
Open regedit and browse to
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}
If the upperfilters  data has anything other than kbdclass, remove it leaving only kbdclass,

Your system files have been infected, Master is correct, and you will need to backup anything you have on this system and reinstall windows AFTER YOU FORMAT THE DRIVE.

Do you know what the virus was?

edbedbCommented:
It's a little soon to be formatting the drive. Try my suggestion for the keyboard first. Let me know if you need more explicit instructions.

edbedb: I did try your suggestion and it worked! Thanks... but now i need to fix the NIC.

Yeah,i think fomatting the drive would be my last thing to do... Everything else seems to be working correctly except for this two issues...well, one issue now..

In the Device Manager.right click the NIC and select properties. Select the details tab and use the drop down to check for any upper/lower filters.

nothing showing for upper and lower filters.

edbedbCommented:
In the Device Manager, select the Drivers tab then click Driver Details. Make a note of the files listed then remove the NIC. After it's uninstalled use Windows Explore to locate and delete them.
Then try re-installing the NIC.

OKay, under driver details this is what is says: "No driver files are required or have been loaded for this device.
then when i try to uninstall it says the following: Failed to uninstall the device.the device may be required to boot up the computer.

Try deleting the card in safe mode (without networking)
That should definately work.

uninstalling does not work, even in safemode without networking...

MaSTeRiToCommented:
Maybe there's some "ghost" nic that causes this?
Open a command prompt and enter:

set DEVMGR_SHOW_NONPRESENT_DEVICES=1

then, in the same command prompt, launch device manager:

devmgmt.msc

In device manager, select View, Show Hidden Devices, then expand the
Network Adapters node and delete all the unwanted devices (they should be
grayed out).
