It is a common perception that you need expensive antivirus tools to clear your system, but that’s not the case. You can use Windows because there are many free tools available, such as Microsoft Defender, Command Prompt, and Safe Mode. However, some people don’t know how to remove virus without antivirus. This article includes the easiest steps to clean your PC. If these steps still don’t work because of the advanced viruses, reliable antivirus software is still needed.

How to Remove Virus Without Antivirus? Scan with Microsoft Defender Offline
One of the easiest ways to learn how to remove virus without antivirus is when you use Microsoft Defender Offline. This will scan your computer even before Windows fully starts. It’s important because some viruses hide when Windows is fully running, so the offline scan helps detect them even if the normal scan misses them.
Step 1: Open Windows Security

Step 2: Choose Virus & Threat Protection

Step 4: Start the Offline Scan
Click on the Scan now button. This will restart your computer automatically and start the offline scan. Make sure you give it time to complete the scan.
This is a good option for basic protection, but there are limits. This is because the new malware tends to show up every day, and the virus database by Microsoft won’t be able to detect the threats quickly. For example, it won’t be able to detect advanced viruses, ransomware, and rootkits.
If Microsoft Defender is unable to clean your computer completely, you should use another antivirus solution for a deeper scan. This is because the dedicated malware removal tools can detect more threats and remove the hidden infections. For this purpose, you check out the best malware removal solutions, as they will help improve the computer's security.
