Virus Doctor is a rogue security software application that is usually distributed by fake online malware scanners. When the user visits specially crafted webpages, a popup will appear and will invite the user to perform an online scan because it supposedly detected a security issue on the user’s computer. If the user clicks that popup (even if he clicks to close it) a fake online scanner will appear. The scanner will perform a made-up scan that detects a phony malware infection; then it invites the user to download and install Virus Doctor.

If you decide to install Virus Doctor, the rogue will automatically run at startup, and you will be constantly be bombarded with fake security alerts like- such as:


Malicious applications which can contain trojans found on your PC need to be immediately removed. Click here to remove these potentially harmful items immediately with Virus Doctor.

An unauthorized program has been prevented from accessing your PC.#Port:433 from 92.11.127.10

An unidentified program-potentially: %ThreatPath% #malicious and able to modify system files- has been prevented from getting installed on your PC.

(Port scan detected at port %portnumber%.

9Process %Process%# attempted to change the address space.

An unidentified program tries to access your computer

The Virus Doctor rogue will also hijack your browser, display phony system scans that detect numerous phony infected files, and generally try to scare you into thinking your system is infected. Then it will ask you to purchase a Virus Doctor license to remove the infection it detected. Yeah, but since Virus Doctor is a rogue you would be paying for a fake security software application that claims to be able to remove a phony infection.



Automatic removal guide
Step 1. If you have a printer, make sure to print out this tutorial. If you do not have a printer, save this tutorial, go out to a copy center and print it out there. If you do not have a printer and do not want to go out, then use the pen and paper method: grab a pen and a piece of paper and write down the instruction presented in the steps below. In the process of eliminating Virus Doctor from your machine you will need to shut down the browser. And since this will also shut down the tutorial, you need to know what you should do next.

Step 2. You will have to install Malwarebytes’ Anti-Malware. In this regard you need to download the software’s setup executable. Just click this link and save the .exe file on your computer (preferably on your desktop).

Step 3. Double click the Malwarebytes’ Anti-Malware setup executable. It should be on the desktop under the name mbam-setup. This will launch the installation process. If you already know how to install a piece of software, proceed to step 4. If you do not know how to do this, we’ll walk you though it all:



- The Select Setup Language window should have popped up. By default, the language in which the software will be installed is set to English, but you can change this. The software provides support for 30+ languages. After selecting the language of your choice, click OK. It would be best to just leave it set to English though.



- The Malwarebytes’ Anti-Malware Setup Wizard will now popup. Just click Next.



- You will be presented with the License Agreement. Click I accept the agreement and then click Next. If you do not accept the agreement you will not be able to continue.



- Keep clicking Next until you get to the Ready to install window. Now click Install. After the installation process completes click Finish. Do not uncheck the boxes next to Update Malwarebytes’ Anti-Malware or Launch Malwarebytes’ Anti-Malware.















Step 4. The Malwarebytes’ Anti-Malware application will launch automatically. The Perform quick scan option should be checked by default – if it isn’t then check it and then click Scan. You are well advised to close all running apps before clicking scan. This will ensure the scan for Virus Doctor will complete swiftly.



Malwarebytes’ Anti-Malware will start scanning your files for signs of Virus Doctor. This may take a while, so be patient. It all depends on how powerful your computer is and how many files Malwarebytes’ Anti-Malware has to scan.



When the scan for Virus Doctor is complete you will be presented with a notification box. Click OK to close the notification box and go to the main Scanner screen. Click Show Results and you will be presented with a list of all the infected files Malwarebytes’ Anti-Malware has detected.





Step 5. Click Remove Selected and Malwarebytes’ Anti-Malware will remove all the infected files it has detected. It may be necessary to restart your computer in order to remove some of these files. After Malwarebytes’ Anti-Malware is done removing all the infected files, it will open Notepad and present the scan log to you. You can review the log at your leisure – save it If you want.



Step 6. Close Malwarebytes’ Anti-Malware and you’re done. No traces of Virus Doctor should be left on your computer.
