Windows Antivirus Master Removal With The Activation Key

1. Open the Windows Antivirus Master and select the ? on the top right next to Settings and then select Register.


2. Next, use one of the following keys to activate it temporarily.

Registration Keys:

After it has been registered, we will then download a legitmate malware removal program “Malwarebytes” and use it to do a complete scan of the PC which should remove this and any other malwares already on your system.

Now download Malwarebytes Anti-Malware by clicking the link below. Unfortunately, Anti-Virus software’s like Norton, AVG and McAfee will not protect you from Malwares which can cause severe corruption so we need Malwarebytes to do a full scan. I highly recommend getting the premium version which will protect you in real-time from getting infected in future from malwares that can cause corruption, but if you do not want to buy then you can just get the free version.

Malwarebytes Antimalware

After it has been downloaded, install it. Open it and go to the Scan Tab -> Custom Scan -> put check in all boxes in the left pane, and select your drives in the right pane. Make sure you select all the boxes in the left pane including “Scan for Rootkits” and then Click “Scan” and wait for scan to finish, this can take 4 to 6 hours, once scan finishes, select “Quarantine All”


Windows Antivirus Master Removal Via Safe Mode  with command Prompt

Reboot your computer in Safe Mode.

Windows XP/Vista/7

Restart the computer and repeatedly tap F8 key until you see the advanced boot menu. If you do not see the advanced boot menu, it means you’ve made a mistake. The duration to press F8 is very short therefore you have to repeatedly press the F8 key until you see the advanced boot menu.

Once you see it, choose “Safe Mode with Command Prompt


Use your windows login and password, as you do in the normal mode. After you’re logged in the computer will start up in safe mode with command prompt (which is a black dos type window). Once you’re in, type explorer in the command prompt and hit enter.


Next, open notepad from Programs or simply hit Windows key and Press R and type notepad in the run dialog. After notepad opens up, copy paste the text below:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run] “GuardSoftware” =-

[HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon] “Shell”=”explorer.exe”


Save this file as fixshell.reg -> File -> Save As (name the file fixshell.reg) and choose type as All Files so it can get the custom extension of .reg


Now double click the file and select YES for the registry editor prompt. Reboot your computer and the master antivirus should be gone. Reboot normally, via Shutdown -> Restart button from the Start Menu.
