# Removing Viruses and Malware from Windows Computers
**Excerpt:** Learn how to identify, remove, and prevent viruses and malware on Windows PCs with this comprehensive guide from Cape Town's trusted laptop repair experts.
## Understanding the Threat: Viruses vs. Malware
Before diving into removal techniques, it's important to understand what we're dealing with. **Malware** is an umbrella term that includes all malicious software, while **viruses** are just one type of malware that replicates itself by infecting other files.
Common types of malware include:
- **Viruses** - Self-replicating programs that attach to other files
- **Trojans** - Disguised malicious programs that appear legitimate
- **Ransomware** - Encrypts your files and demands payment
- **Spyware** - Secretly monitors and steals your personal information
- **Adware** - Displays unwanted advertisements and pop-ups
- **Rootkits** - Hide deep in your system to avoid detection
## Recognizing the Signs of Infection
At Planet Computers, we see these warning signs daily. Your Windows computer might be infected if you notice:
- Significantly slower performance than usual
- Frequent system crashes or blue screens
- Unexpected pop-up advertisements
- Browser redirects to unknown websites
- New toolbars or programs you didn't install
- Disabled antivirus software
- High network activity when you're not using the internet
- Missing or corrupted files
- Unusual hard drive activity
## Step-by-Step Malware Removal Process
### Step 1: Disconnect from the Internet
Before starting the removal process, **disconnect your computer from the internet** to prevent further data theft or additional malware downloads. Unplug your ethernet cable or disable Wi-Fi from your network settings.
### Step 2: Boot into Safe Mode
Safe Mode loads Windows with minimal drivers and programs, making it easier to remove stubborn malware:
1. Press **Windows + R** to open the Run dialog
2. Type `msconfig` and press Enter
3. Click the **Boot** tab
4. Check **Safe boot** and select **Network**
5. Click **OK** and restart your computer
Alternatively, for Windows 10/11:
1. Hold **Shift** while clicking **Restart** from the Start menu
2. Select **Troubleshoot > Advanced Options > Startup Settings**
3. Click **Restart** and press **5** for Safe Mode with Networking
### Step 3: Run Windows Defender (Built-in Protection)
Windows comes with built-in antivirus protection that's surprisingly effective:
1. Open **Windows Security** from the Start menu
2. Click **Virus & threat protection**
3. Select **Quick scan** or **Scan options** for a full scan
4. Choose **Full scan** for comprehensive protection
5. Let the scan complete and follow any removal recommendations
### Step 4: Use Malwarebytes Anti-Malware
Malwarebytes is excellent at catching threats that traditional antivirus might miss:
1. Download Malwarebytes from the official website
2. Install and launch the program
3. Click **Scan** to start a threat scan
4. Review the results and click **Quarantine** for detected items
5. Restart your computer when prompted
### Step 5: Run Additional Scanning Tools
For stubborn infections, we recommend these additional tools:
**AdwCleaner (for adware and browser hijackers):**
- Download from Malwarebytes website
- Run as administrator
- Click **Scan Now** and remove detected items
**ESET Online Scanner:**
- Visit ESET's website and run their online scanner
- Allow it to scan your entire system
- Remove or quarantine any threats found
## Advanced Removal Techniques
### Using System Restore
If malware has severely damaged your system, System Restore can roll back your computer to a previous clean state:
1. Type **System Restore** in the Windows search bar
2. Select **Create a restore point**
3. Click **System Restore**
4. Choose a restore point from before the infection
5. Follow the wizard to complete the restoration
### Cleaning Browser Settings
Malware often modifies browser settings. Here's how to clean popular browsers:
**Google Chrome:**
1. Click the three dots menu > **Settings**
2. Go to **Advanced > Reset and clean up**
3. Click **Clean up computer** and **Restore settings to original defaults**
**Microsoft Edge:**
