How to clean my computer from virus?

Keeping your computer safe from viruses is essential to ensure its optimal performance and safeguard your data. Viruses can slow down your system, corrupt files, and even steal your sensitive information. To protect your computer and clean it from viruses, follow the steps outlined below.

1. Install Reliable Antivirus Software

The first step in cleaning your computer from viruses is to install a trusted antivirus software. There are various options available, both free and paid. Make sure to choose one that offers real-time protection and regular scanning options.

2. Update Your Operating System

Frequently updating your operating system is crucial as it includes vital security patches and fixes. These updates patch vulnerabilities that hackers can exploit to infiltrate your system with viruses. Set your computer to automatically install updates for the latest protection.

3. Disconnect from the Internet

Before cleaning your computer from viruses, it is recommended to disconnect from the internet. By doing this, you stop the virus from potentially spreading to other devices or downloading additional malware.

4. Perform a Full System Scan

Once your antivirus software is up to date, perform a full system scan. This scan will detect and remove any infected files present on your computer. The process may take a while, so be patient and let the software do its job.

5. Remove Detected Viruses

After the scan is complete, the antivirus software will display a list of detected viruses. Follow its instructions to remove or quarantine the infected files. Quarantine allows you to isolate the infected files without deleting them, just in case there are false positives.

6. Delete Temporary Files

Viruses often lurk in temporary files, so deleting them helps ensure your computer is fully clean. To do this, press the Windows key + R, type “%temp%” (without quotes), and hit Enter. Select all the files that appear and delete them permanently.

7. Clear Your Browser’s Cache

Some viruses target web browsers and install malicious extensions or cookies. Clearing your browser’s cache regularly helps eliminate these threats. Refer to your browser’s settings to find the option to clear cache.

8. Change Your Passwords

As an additional security measure, it is wise to change all your passwords, especially those associated with sensitive accounts. This step helps protect against any potential data breaches that may have occurred before virus removal.

9. Create Regular Backups

Backing up your important files on a regular basis is essential. In the unfortunate event that your computer becomes infected with a virus, having recent backups will allow you to restore your data easily without losing much information.

10. Be Cautious of Email Attachments and Downloads

Exercise caution when opening email attachments or downloading files from unknown sources. Viruses often spread through these mediums, so only open or download files from trusted senders or reputable websites.

11. Avoid Clicking on Suspicious Links

Clicking on suspicious links, especially in emails or pop-up ads, can lead to malware infections. To keep your computer clean from viruses, refrain from clicking on anything that seems dubious or unsolicited.

12. Educate Yourself

Stay informed about the latest virus threats and how to protect yourself by keeping up with reliable sources of information. Knowing about different types of viruses and their potential risks empowers you to take appropriate preventive measures.


1. How can I tell if my computer has a virus?

Look out for symptoms such as slow performance, unexpected pop-ups, disabled antivirus software, or strange behavior on your computer.

2. Can I clean my computer from viruses without using antivirus software?

While it’s possible to manually remove viruses, it requires technical expertise and is not recommended for inexperienced users.

3. Can a factory reset remove viruses?

Yes, a factory reset will remove viruses, but it will also erase all your data, so make sure to backup important files before performing a reset.

4. How often should I scan my computer for viruses?

Regularly scanning your computer for viruses is crucial. Aim for at least once a week, or more frequently if you visit high-risk websites or download files frequently.

5. Can viruses hide in my computer’s RAM?

While it is technically possible, viruses hiding in RAM is rare. Most antivirus programs are capable of detecting and removing viruses from RAM.

6. Will a virus scanner slow down my computer?

While performing a scan, antivirus software may temporarily slow down your computer as it utilizes system resources. However, modern scanners are designed to minimize their impact on performance.

7. What is the best antivirus software?

There are several reliable antivirus software options, such as Norton, McAfee, Avast, and Bitdefender. Each has its own strengths, so choose one that meets your specific needs.

8. Can I get a virus from visiting websites?

Yes, visiting compromised or malicious websites can lead to virus infections. Make sure to keep your browser and antivirus software up to date to mitigate these risks.

9. Are Mac computers immune to viruses?

While Mac computers are generally less prone to viruses compared to Windows PCs, they are not completely immune. It’s still important to use antivirus software and practice safe browsing habits.

10. Can mobile devices get viruses?

Yes, mobile devices can get infected with viruses and malware. Similar precautions should be taken, including using reputable antivirus software and being cautious of app downloads.

11. Should I run multiple antivirus programs?

Running multiple antivirus programs simultaneously can cause conflicts and system instability. It is recommended to use only one antivirus program at a time.

12. What if my computer is already infected and won’t turn on?

If your computer is severely infected and unresponsive, it may require professional help. Contact an expert in computer repair or take it to a trusted service center for assistance.
