I got the newest incarnation of this Rogue Spyware yesterday. I've had it a few times over the years and pretty much know what to do. I got into safe mode, ran Malware Bytes and a registery cleaner, Trojan Remover. I was able to get rid of all files associated and fixed all apparent registery issues. I restarted my computer and re-ran this programs. All clean. BUT now my pc is not able to identify the network. I have my pc on my home network via eithernet cable from the router. I undid the cable and put my usb wireless in to see if i could connect to the wireless portion of my network. Once again, found network but stuck on identifying.

I'm stuck, any ideas?

If you can get hold on another Win 7 machine that would be the best.

Interesting...
Usually Windows 7 has plenty of tdx.sys file backups.

Following steps involve registry editing. Please create new restore point before proceeding!!!


In any case....
On your Vista computer navigate to C:\Windows\system32\Drivers folder, copy tdx.sys file from there and paste it to the very same location on Windows 7 computer.

Next....


Download Seven.zip file from here: http://www.smartestcomputing.us.com/files/download/9-registry-network-keys/
Unzip the file.
You'll find three files inside.
Right click on tdx.reg file, click "Merge".
Allow registry merge.

Restart computer.

Post new Farbar Service Scanner log.

Possibly tdx.sys from Vista won't work on Windows 7.

Try "Last known good configuration".

It's very possible your Windows installation is seriously corrupted.
As I said normally there is plenty of backups of that file (as well as other files).
