How To Remove Malware And Viruses From PC? [5 Methods]

Read on to learn how you can free your PC from viruses once and for all.

Expert Verified By

Malware, like Trojan, Spyware, and Worm, can harm, infiltrate, or exploit a computer system without the user’s awareness. Meanwhile, viruses, such as Conficker, WannaCry, and Zeus, are a type of malware that can replicate itself to spread from one computer to another by attaching to different programs or files. When users click on suspicious files, these viruses get transmitted to their computers to damage or steal data. Thus, it is essential to know how to remove malware and viruses from your PC in case you ever encounter them. 

Key Takeaways

  • Malware and viruses can delete your data, infect the system files, and steal important information from your computer.
  • They are transmitted to your device when you open suspicious links or download from unsecured software, or they could travel through your device’s network.
  • You can reset your PC, launch it into Safe Mode, or perform antivirus scans to eliminate malware and viruses.

Tip: Regularly scan your PC for such threats.

Microsoft Defender is a built-in antivirus in Windows PC that can quickly look for and discard these hazards on your computer. I ran the scan, and it detected an issue with my PC’s security features. Therefore, I took the necessary measures to resolve it. Resort to the following method to scan with Microsoft Defender.

Install Antivirus Software

I recommend downloading at least one antivirus software on your computer so it can timely detect and prevent virus or malware attacks. Reliable third-party antivirus software, like McAfee and Avast, identify malware and viruses and block them before they can threaten your system’s data and files. Deep scan your PC using antivirus software to find and resolve potential malware threats and hidden viruses. 

Use Clean Boot On Windows PC

A clean boot helps identify if third-party software or an installed application is the source of malware attacks on your computer. Scan the PC with Microsoft Defender to look for viruses or malware. Once started, go to Settings and run Microsoft Defender Offline Scan to check whether the problem exists within the third-party apps or the Windows environment.

Run A Scan In Safe Mode

The system boots up with the minimum drivers and services needed for Windows’ operation. Importantly, turn off the computer’s WiFi so any viruses or malware may not be able to hinder the working while it is in Safe Mode. This is how you can proceed. 


  1. Pick Safe Mode: Open System Configurations > Head to the Boot tab > Select Safe Mode and mark Network under it > Apply > OK.

How Do Malware And Viruses Affect Your PC?

The presence of malware and viruses on your PC could adversely impact several areas of its functioning. For instance, it can;

  • Slow down your computer and occupy system memory.
  • Corrupt your files and data on the computer, which could result in the loss of essential data.
  • Delete files or programs on your system.
  • Steal confidential information from your PC, such as passwords, bank account numbers, and credit card details.
  • Repeatedly display intrusive and unwanted ads on your screen as pop-ups.
  • Lock you out of your computer and take over the entire system.
  • Quickly spread onto other devices connected to the same network, like smartphones.

Final Words

I highly advise to take precautionary steps to protect your system from dangerous malware and viruses. Occasionally scanning your computer for viruses and threats, along with utilizing a VPN, is one way to avoid such attacks.

Furthermore, avoid clicking on suspicious links or opening illegitimate software since they are likely to carry a virus. It would also help to be vigilant when downloading apps or software from unknown sources. Remember that a site address starting with HTTPS is more secure and reliable than HTTP since the former has an extra security layer due to the Secure Sockets Layer (SSL) Certificate.

Apart from these, keep your antivirus software and operating system up-to-date with the latest versions. Besides, you can enable a Firewall on your PC to block unauthorized personnel from accessing your files or data.
