How to remove viruses yourself – safely

Suspect your computer has a virus or malware? The most common signs are:

• The computer has slowed down significantly
• The browser opens strange pages on its own
• Ads appear everywhere – even on pages that shouldn't have them
• The computer starts or shuts down by itself
• You can't open files or programs
• Strange error messages appear

Here is a step-by-step guide to removing viruses. Follow the instructions in order.

Step 1: Disconnect from the network

First, disconnect from the network (WiFi or cable). This prevents the virus from sending data out or downloading more malware.

Step 2: Start the computer in Safe Mode

Safe Mode starts only essential programs. Most viruses don't start in this mode, making them easier to remove.

Windows:

1. Press Windows + R
2. Type msconfig and press Enter
3. Select the "Boot" tab
4. Check "Safe boot" and select "Minimal"
5. Restart the computer

macOS:

1. Shut down the computer
2. Hold the Shift key while starting up
3. Release when you see the Apple logo

Step 3: Back up your most important files

Before doing anything else, copy your most important files (photos, documents) to an external drive or USB stick.

Step 4: Run a virus scan

Use the built-in antivirus or download a free tool.

Windows Defender (free, built-in):

1. Open Settings → Update & Security → Windows Security
2. Select "Virus & threat protection"
3. Click "Scan options"
4. Select "Full scan"
5. Wait until the scan is complete

Malwarebytes (free, very effective):

1. Download: malwarebytes.com
2. Install and open
3. Select "Scan" → "Threat Scan"
4. Remove all detected threats

Step 5: Remove suspicious programs

Go through installed programs and remove anything you don't recognize or remember installing.

Windows:

1. Open Settings → Apps → Apps & features
2. Sort by "Install date"
3. Remove all suspicious programs

Step 6: Clean up browser extensions

Browser extensions are a common source of viruses – especially "toolbars" and "ad blockers" you didn't install yourself.

• Chrome: Settings → Extensions
• Firefox: Settings → Extensions and Themes
• Edge: Settings → Extensions

Remove anything you don't recognize or need.

Step 7: Update the operating system and programs

Updates fix security vulnerabilities. Install all updates.

Step 8: Change your passwords

If your computer has had a virus, change the most important passwords:

• Email
• Online banking
• Social media
• Other important services

Use strong passwords and enable two-factor authentication.

Summary

Virus removal often works on your own, but if your computer is seriously infected or you're unsure what to do – contact a professional. A botched cleanup can make things worse.
