Please follow the instructions below. Although both of the items below may, or may not be present, please check for them.. If you find one, remove it as directed.. On the other hand, if the "bad" file isn't there, just move on to the next step.:
Look for the file below and if there...:
Delete it (or move/rename) and Reboot.
1.Click on the Start button, select "Run", then type "devmgmt.msc" in the blank area, without the quotes, then click on OK.
2. Once in Device Manager, click "View" in the upper left, select "show hidden devices/drivers".
3. Then click on "non plug and play drivers/devices", and find TDssserv.sys
4. If it's there, right click it, then select disable, then restart the computer.
5. then check if the problem still persists. good luck!
And finally, to make sure other trojans aren't on the computer:
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. If you can't start the computer into "normal" windows, try installing, updating, and running the scans AFTER the computer is started into Safe Mode.. 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.
