I have a Compaq HEL81 running WinXP with SP2.
I use Intel PROset Wireless.
A few days ago I had an unprovoked trojan attack (I had not downloaded or opened anything when it happened).
I ran spybot S&D, Adaware, Malwarebytes, which detected various trojans, rootkits and backdoors which I chose to remove.
Then I ran Kaspersky Tool and removed some threats, while others were unremoveable. I then ran Combofix, and my Intel PROset Wireless stopped working.
I checked my device manager, and all network devices have a code 39 error.
I read online about replacing NDIS.SYS file in the System32/drivers folder with the one from the ServicePackFiles folder, to fix the problem, but then my computer would get stuck in a boot-up/BSOD loop, unable to get to Windows.
I then deleted NDIS.SYS from my System32/Drivers folder by way of the command prompt, as it was the only way to get back into Windows.
I still have the code 39 error on my network devices, but the pop-ups from the trojans are gone. I attempted to do a system restore, but it won't work (posibly because my HD has been very full).
I would really appreciate it if anyone can give me a clue as how to proceed.
Thanks very much,
