Matthew Davies Discusses How to Clean a Computer Infected with a Virus or Malware


Malware is like an accident. You think it would never happen to you until it does. Like an insurance policy, antivirus software is your safety measure against malware and viruses. According to Matthew Davies, antivirus software and security tools protect your computer from being infected by malicious programs. However, if your computer is already infected heavily, here’s what you can do:

The Steps

  1. Backup all your important files and documents – While you remove infected programs from your computer, you may come across unprecedented circumstances where you lose all your data due to formatting or any other event. It is a safety measure to backup all your important files and documents so that you don’t lose cherished memories or important work assignments. 

However, it is important to note that some of your files may be infected by malicious programs. You want to backup all your data on a clean and isolated hard disk so that the infection doesn’t spread. After you are done removing viruses and other malicious programs from your computer you have to scan the backup hard disk for any infected files and remove them accordingly. 

  1. Boot into safe mode with networking enabled – 
  • Unplug any removable devices like USB drives, external hard disks, or CDs and DVDs 
  • After that restart your PC while pressing the F8 key repeatedly till you are introduced to the Windows Advanced Options Menu 
  • Here select the “Safe Mode with Networking” option
  • This limits Windows startup with critical processes and prevents most other programs including malicious software to start up
  • If you are using Windows 8 or 10, you can search for Advanced Startup options in the search bar>Change advanced startup options and access the same options after your computer restarts 
  1. Delete all the temporary files – To scan for malware and viruses smoothly, you need to delete all the temporary files from your computer. To clean up the temporary files, select one of the drives on your computer. For instance, you can select C:/ drive or D:/ drive and right-click on them. From here you click on Properties>Disk Cleanup. Select temporary files from the popup menu and delete them. 
  2. Remove malware with anti-malware tool – Open your browser and download one of the reputed anti-malware tools like Kaspersky, BitDefender, or Norton. Most of them provide a trial period of two weeks or a month. Run a system-wide scan and remove all the malicious files from your computer. If you are on Windows 10, you can also use Microsoft’s own Windows Defender. Make sure to update all the antivirus definitions and update Windows Defender if you intend to use it. After you have cleaned your computer you can restart and reset your browser settings if it has been changed by malware.


Matthew Davies believes that you should always use a potent anti-malware tool to keep your computer free from viruses and malware. You should also keep them up to date so that they can work properly.
