How to Remove Malware and Viruses from Your Laptop or PC
The Importance of Protecting Your Devices
Malware and viruses can wreak havoc on your laptop or PC, leading to stolen data, slower performance, and even system crashes. Whether you’re using your device for work, gaming, or personal use, it’s crucial to keep it safe from these threats. Fortunately, removing malware and viruses from your computer is possible, and with the right tools and techniques, you can do it yourself.
In this guide, we’ll walk you through how to remove malware and viruses from your laptop or PC, providing easy-to-follow steps and tips for keeping your device secure in the future.
1. Identifying Signs of Malware or Virus Infection
Before removing malware or viruses, it’s essential to recognise the symptoms of an infection. Here are some common signs that your laptop or PC might be infected:
- Slow Performance: One of the most noticeable signs of malware or virus infection is a sudden drop in your computer’s speed. If your laptop or PC takes longer to boot or open files, malware might be the culprit.
- Pop-ups and Unwanted Ads: If you’re seeing frequent pop-up ads or strange windows appearing on your screen, this is a red flag. These ads often come from adware or malware.
- Unusual Behaviour: Your device may start acting strangely, such as opening applications on its own or displaying error messages that you’ve never seen before.
- Disabled Security Programs: If your antivirus software suddenly stops working or you’re unable to access certain security settings, a virus may have disabled them.

2. Step-by-Step Guide to Removing Malware and Viruses
If you suspect your laptop or PC has been infected with malware or viruses, follow these steps to remove them effectively.
Step 1: Disconnect from the Internet
The first thing you should do is disconnect from the internet. This prevents malware from communicating with its source or spreading further. Unplug your Ethernet cable or disable your Wi-Fi until you’re confident the infection is removed.
Step 2: Boot into Safe Mode
Safe Mode allows your computer to run with minimal drivers and background processes, making it easier to identify and remove malware. Here’s how to boot into Safe Mode:
- For Windows: Restart your computer and press the F8 key before Windows starts loading. Choose “Safe Mode with Networking” from the menu.
- For Mac: Restart your Mac and hold down the Shift key until the Apple logo appears. This will boot your Mac into Safe Mode.

Step 3: Delete Temporary Files
Temporary files can sometimes harbour malware. Deleting these files can help remove malware and speed up the virus scan process.
- On Windows, use the built-in Disk Cleanup tool to remove temporary files.
- On a Mac, use the “Go to Folder” function and typeÂ
~/Library/Caches to locate and delete cache files.

Step 4: Install and Run Antivirus Software
If you don’t have antivirus software installed, now is the time to get it. Choose a reliable antivirus program, such as those listed in The Best Antivirus Software to Protect Your Devices in 2024. Install the software and run a full system scan to detect and remove malware.
Some antivirus programs allow you to perform an offline scan, which is highly effective at removing malware that operates in the background.
Step 5: Use Malware Removal Tools
Antivirus software is great, but for a more thorough clean, consider using dedicated malware removal tools. Programs like Malwarebytes or HitmanPro specialise in detecting and removing malware that traditional antivirus software might miss.
- Download and install the software.
- Run a full scan to detect hidden malware, and follow the prompts to remove any malicious files.

- For Chrome: Go to “Settings,” then “Privacy and Security,” and select “Clear Browsing Data.”
- For Firefox: Go to “Options,” then “Privacy & Security,” and click on “Clear Data.”
- For Safari: Go to “Preferences,” then “Privacy,” and choose “Manage Website Data.”
