Virus/Malware Removal (PC)

A quick guide to removing viruses and malware from your PC.

Step 1: Getting Ready For A Scan
Before you can begin to remove viruses or malware from your computer, you will need to have a program to do so. Here are a few free options:

Anti-Virus

Anti-Malware

This is not a definitive list, other options may work.

Note: There should only be one anti-virus program on a PC, more than one may conflict and cause issues. Malwarebytes can be installed along side with an Anti-virus however.

Step 2: Scanning
  1. Launch the Anti-Virus or Anti-Malware program you will be using
  2. Make sure the software you will be running (Malwarebytes, Microsoft Security Essentials, Avast!, etc.) is up to date. 
  3. Run a scan. There will often be a quick or full option, you will likely want the full scan. If there isn't any option like this, just let it run. 
  4. Have remove and viruses or malware it finds and restart the system (which the program may ask for) and see if the problem persists. 
  5. If the problem is still going on it's time to go to Safe Mode.

    Note:If you are unable to open the program (Step 1) it may be the virus/malware preventing this. In this case, jump straight to Safe Mode. 

Step 3: Getting Into Safe Mode

At this point there will be different instructions if you are on Windows 7 or Windows 8 (or 8.1).

Windows 7 Instructions
  1. Restart the computer
  2. Before you see the Windows logo, hit F8. If you see the logo, you will need to restart and try again. 
  3. Select Safe Mode with Networking

Windows 8 Instructions

  1. If you hold the Shift key while you restart you will get to a set of options.
  2. Click on Troubleshoot
  3. From there go to Advanced Options
  4. Click Startup Settings
  5. Hit the Restart button
  6. Use option 5, Enable Safe Mode with Networking

Windows 10 
  1. If you hold the Shift key while you restart you will get to a set of options. 
  2. Click on Troubleshoot
  3. From there go to Advanced Options
  4. Click Startup Settings
  5. Hit the Restart button
  6. Use option 5, Enable Safe Mode with Networking
Step 4:Once You Are In Safe Mode

Once you are in safe mode you can repeat Step 2, run another scan or update if you couldn't before.There is another program we often use to remove particularly bad cases, and that is Combofix. You can find that here :http://www.bleepingcomputer.com/download/combofix/ . This scan will take a while, depending on your computer's abilities, number of files, and how many infections there are.

If this still does not take care of the issue, or if Safe Mode doesn't stop the virus/malware from affecting the program you are trying to use, the infection is fairly severe. If you feel comfortable troubleshooting on your own, it is a good idea to Google the issue. Some issues may be easier to describe than others, for example, the Department of Justice Moneypak virus as seen below is quite easy to distinguish from other viruses.For other cases either try searching up the symptoms or bring your computer into the ITS Helpdesk.
