I think my computer is getting hijacked.

by Bloodyleaf / December 25, 2008 10:10 AM PST

i suspect that my computer is being hi-jacked because every time i search something on "Google" it would give me the wrong result. For example when I search youtube, it would give me results such as Do you think my computer's getting hi-jacked? Should I post a hi-jack this log?

A Couple More Good Free Antispyware Tools..
by Grif Thomas Forum moderator / December 25, 2008 12:16 PM PST

Please try the steps below:

On a friend or family member's computer, download the Malwarebytes installer and update files from the links below, copy them to a CD or flash drive, then transfer the files to the problem machine and use them.. I use the sites below to download the installer file and the manual updater:

Once downloaded and before transferring them to the problem machine, rename the program installer "mbam-setup.exe" file to something else like "Gogetum.exe", then copy the installer file and the update file to a CD or flash drive.. Transfer the file to the problem machine, then install the "Gogetum.exe" file, then run the update to get the program current.. After that, run a full system scan and delete anything it finds.

Malwarebytes Installer Download Link (Clicking on the links below will immediately start the download dialogue window.)

Malwarebytes Manual Updater link

Next, download the SuperAntispyware program and the manual updater from the links below. After running the Malwarebytes tool above, if you still can't download and install it directly from the problem machine, download it on a friend or family member's computer as well.:


SuperAntispyware Manual Updater

In a few situations, in order for the program to run, it was also necessary to rename the main "mbam.exe" file also after installing it.. It resides in the C:\Programs Files\Malwarebytes Antimalware folder.

Hope this helps and let us know more.

Looks Like A Yahoo Search Problem..
by Grif Thomas Forum moderator / December 26, 2008 10:52 AM PST

Did you try using to do the searches from? Do the same redirected websites show up from the link below:

More importantly, what did the malware scans find, if anything? Have you tried re-running the scans repeatedly, in "Safe Mode", to see if it will get rid of any remanants of malware?

Hope this helps.

Exactly the same problem here.
by astidkalis / December 28, 2008 11:57 AM PST

And also on but not on Yahoo!
Moreover I can't do a Windows Update through Internet Explorer. However, everything works fine in Windows Explorer! (In the search panel: view->explorer bar->search and then search the internet).

I've been working on this and I think I'm getting somewhere: I've noticed that if you delete the following registry key and all its content (export the key an all its content first to put it back!):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility

The problem with the search disappears (you have to restart the browser). However, of course, you also lose all the functionality of the ActiveXs, like flash and Windows update.

Restored the registry key and the problem is back, as expected.

Now you would think that the problem is with one of the numerous subkeys: Tried deleting them all (by editing the reg file, not manually!) keeping just the main key (i.e ActiveX Compatibility with its empty default value) and the problem remains, as if IExplorer is just looking for the presence of the key to continue or not with the hack or other ActiveXs.

That's where I'm at now. I'll keep working on it later. More to follow I hope. Reply if you find something.

BTW I did try do disable all the ActiveXs and it didn't work.

--Never Reinstall!

Be Careful On That One..
by Grif Thomas Forum moderator / December 30, 2008 12:58 AM PST
In reply to: FOUND IT!

Although that particular driver file can be malware, it is also a legitimate Microsoft file. the legitimate file should be located in the "C:\Windows\System32\drivers" directory which is different from the location where you found it. Obviously, a legitimate "wdmaud.sys" file doesn't belong in the System32 folder as you've discovered.. Just a link or two below:

Others should confirm the location of the problem file. It might be beneficial to run a test first by disabling the wdmaud.sys process/service to verify that it's causing the problem. Obviously, it's taken care of your problem but it may not be a universal solution for all. Good find..

Hope this helps.

re: C:/Windows/system32/wdmaud

Was having issue with Google and Yahoo search results getting diverted to other SPAM sites. Spyware and virus protection could not find/repair the exact issue.

Removing the wdmaud file seemed to work for me too.

Same problem issue returned
by siouxsy / January 23, 2012 7:46 AM PST

Still having an issue with Google search results being redirected to SPAM sites.
The wdmaud file has been replicated and replaced. Now unable to access my Calendar tab from my Gmail account.
Noticed this file also appears in the System32 folder on another computer. Removing wdmaud may not help.

After all the other trojans that were found, may need to reboot and reinstall programs on this XP computer, as seemingly unable to find the problem issue.

astidkalis instructions fixed the problem for me too.

Find C:/Windows/system32/wdmaud.sys

Delete it (or move/rename) and Reboot.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
