My gf was using my pc to game, came home from work and there’s a Trojan installed. I’ve been able to delete the Trojan from my hard drives but the effects are still there and are as follows:
There’s a Hidden Admin account I can’t see
My Antivirus was removed
Can’t download any files
portable USB files won’t install any software
Windows Defenders whitelist is blocked from editing
Force reset is disabled
Any Security audit is disabled
Updating windows through any means is disabled
Can’t connect to update repositories


Basically to get the virus off I made a little batch file to commandeer the infected files and take ownership of them then promptly delete. But if I try to do anything to revert the virus havoc I’m met by a lack of admin privileges or windows just won’t do it. Any ideas on my next step?

From Safe Mode with Networking.

Please download the FRST 32 bit or FRST 64bit version to suit your operating system. It is important FRST is downloaded to your desktop.

If you are unsure if your operating system is 32 or 64 Bit please go HERE.

Once downloaded right click the FRST desktop icon and select "Run as administrator" from the menu"

If you receive any security warnings, or the User Account Control warning opens at any time whilst using FRST you can safely allow FRST to proceed.
FRST will open with two dialogue boxes, accept the disclaimer.

  1. Accept the default whitelist options,
  2. If the additions.txt options box is not checked please select it.
  3. Then select Scan

Frst will take a few minutes to scan your computer, and when finished will produce two log files on your desktop, FRST.txt, and Addition.txt. They will display immediately on the desktop, but can be reopened later as a notepad file.

It’s extremely tricky to get the computer into safe mode. Shift + restart just restarts the computer.

Boot in the Recovery Environment

  • To enter the Recovery Environment with Windows Vista and Windows 7, follow the instructions below:
  • Restart the computer
  • Once you've seen your BIOS splashscreen (the computer manufacturer logo), tap the F8 key repeatedly until the Advanced Boot Options menu appears
  • Use the arrow keys to select Repair your computer, and press on Enter
  • Select your keyboard layout (US, French, etc.) and click on Next
  • Click on Command Prompt to open the command prompt
    Note: If you can't access the Recovery Environment using the F8 method above, you'll need to create a Windows installation or repair media. It can be made on the computer itself or another one running the same version of Windows as the one you plan to use it on. For more information, check out this tutorial on SevenForums.
    • To enter the Recovery Environment with Windows 8 or Windows 8.1, follow the instructions in this tutorial on EightForums
    • Note: If you can't access the Recovery Environment using the method above, you'll need to create a Windows installation or repair media. It can be made on the computer itself or another one running the same version of Windows as the one you plan to use it on.
      • To enter the Recovery Environment with Windows 10, follow the instructions in this tutorial on TenForums
      • Note: If you can't access the Recovery Environment using the method above, you'll need to create a Windows installation or repair media.

  • Note: Replace the letter e with the drive letter of your USB Flash Drive
  • FRST will open
  • Click on Yes to accept the disclaimer

Or, if you are able to download FRST to your USB and drag it to the desktop of the infected machine and see if you are able to run it.

Another trick you may be able to do...

Open the command prompt and type hh h (or Do this from the start search bar)
Hit enter.
Click on the question mark in the top left of the user interface.
Click on Jump to URL
Type in this URL https://toolslib.net/downloads/viewdownload/85-processclose/
Save Process Close to your desktop.
Make sure that you have FRST on the desktop as well.
Right click Process close run as admin. ( in your case double click as you may not have admin privilege )
Select [...] Browse.
Go to the users folder, double click it.
Then select your user id
Then select Desktop
Right click FRST and run as admin.

I tried all the steps you recommended, I run into a pack of admin privileges or windows won’t do anything. I think a hard reset is in order. How do I go about doing that knowing my situation?

Also, this tool may run from a USB if you drag it to your desktop.
May also be able to download it with the hh h browser.

Have you tried the steps in my other post involving the hh h browser and process close?
windows doesn’t do anything, I get no error yet it doesn’t start anything. I somehow completed a sfc /scannow and have the logs for it. You want to see the cbs.log?

Can you use the USB with windows 10 on it to boot into the recovery console?

Also, since you were able to pull off a sfc /scannow I think you might be able to enable the built in admin account or create a new account through the command prompt; then use the Bootsafe tool to enable safe mode so we can get a FRST scan from the infected account.



Once you have created the new account log out of the infected account and run the bootsafe tool from the new account.


Once in safe mode run a FRST scan on the infected account.
