Hi, today i got the duty of fixing a coworker's pc. It's running Windows Xp and it is there home computer, so they would not want it to be formatted. Until yesterday, they were hit bad with a virus (my guess is that it is wsaupdater one) I've tried two methods in total from this forum on how to fix it. Both failing in about 4 attempts at both in total. The methods I have used are these:


http://www.geekstogo...Off-t15771.html

And one where is said to go to
d:
cd i386.....etc

As for the second method. When trying to go to the i386 directory, it said " Access is denied"
So the method was never completed.

Any help would be much appreciated. :)

Get PC Regedit
from the link on the lower half of this page:
http://www.raymond.c...ing-in-windows/

The page explains how to use it to fix a no logon condition. If userinit looks normal then check the value of shell which should be explorer.exe.

From a recent post we can see these Netsky infection points in an OTL log:

NetSvcs: BtwSrv - C:\WINDOWS\system32\BtwSrv.dll (FTD2XX Software Technology)
NetSvcs: Iprip - C:\WINDOWS\system32\Ipripv32.dll ()

These last two will mess up your internet. See:

If in doubt compare to a working system.
