Ndis.sys error due to virus - cant boot windows

By pita_ruben ·
Hello everyone,

Hope you guys are ok. My Windows give me a blue screen and reboot itself over and over again. My ndis.sys file was infected with virus I cleaned the OS 100% with both my Antivirus program (Norton Corporate Edition 10.1.6.600) and the Antispyware Malwarebytes.

I tried copying the ndis.sys file from another healthy PC and from c:\Windowws\ServicePackFiles into the c:\Windows\System32\Drivers but my laptop contine with the same problem.

When I boot the the Recovery Console and either rename or delete the ndis.sys file then Windows load properly but my network card appears with a admiration yellow mark and doesnt work.

My system restore doesnt have any restore point before the infection.

Thank you so much in advance for you always opportune and valuable support.

A couple of things to try

Reinstall the drivers for your network card.

Try a Repair/Install of the Operating System.

Run this Rootkit Revealer GMer

If you are still having problems try this.

Download Combofix and rename the executable Combofix.exe to cfix.exe before running it.

When all is clear you may need to tidy up the Registry.

Registry:

Download and install CCleaner to tidy up your Registry. Backup the Registry as you go along, rescan again and again saving as you go until there are no errors left.

Cleaner: Windows

When you first open Ccleaner you will have an option to Analyze or Run Cleaner, after checking the left Pane and making your choices. Delete all Temp Files. If you scroll down you will see a greyed out box that has Advanced next to it. Left click on it and keep pressing OK to all of the responses. I normally Untick Windows Log Files and Memory Dumps as they may come in handy.

You don't have to install all of the add ons or shortcuts just the one to the Desktop.

In the post below you can find the final solution to my issue, since the virus reappeared after the Windows repair and even after a format later.
