Boot into Safe Mode
Restart your computer and boot into Safe Mode. This loads Windows with a minimal set of drivers and programs, which can help prevent the malware from interfering with the removal process.
Windows 10/11: Hold the Shift key while clicking Restart. Then, select Troubleshoot > Advanced options > Startup Settings > Restart. Press 4 or F4 to enable Safe Mode.
Run a Malware Scan
Use a reputable antivirus or anti-malware program to scan your entire system. Some popular options include Malwarebytes, Norton, and Bitdefender. Make sure your software is up-to-date to detect the latest threats.
Quarantine or Remove Threats
The scan will identify any malware on your PC. Follow the program's instructions to quarantine or remove the detected threats. Be sure to remove all detected threats.
Use a Specialized Removal Tool
For stubborn malware, consider using a specialized removal tool. These tools are designed to target specific types of malware that can be difficult to remove with a general antivirus program.
Reset Your Browsers
Malware often modifies browser settings. Reset your browsers to their default settings to remove any unwanted extensions or changes.
Reboot Your PC
After completing the above steps, reboot your PC in normal mode. Run another scan to ensure all malware has been removed.

- Review your system logs: Look for errors or warnings that could indicate a malware infection.
Using Command-Line Tools
Command-line tools can be powerful for detecting and removing malware. Here are some examples:
# Check for suspicious network connections netstat -abno # Scan for modified files sfc /scannow # Examine running processes tasklist These commands can provide valuable insights into your system's activity. Replace `` with actual code.
Example: Identifying a Suspicious Process
Let's say you suspect a process named "evil.exe" is malware. You can use the following command to find its location:
wmic process where name="evil.exe" get executablepath
This command will display the full path to the executable, which can help you determine if it's legitimate or not.
Cleaning a potentially infected file (Linux example)
If you suspect a file contains a virus, you can use ClamAV (an open-source antivirus engine) to scan and remove it.
sudo apt-get update # Update package lists sudo apt-get install clamav # Install ClamAV sudo freshclam # Update virus definitions clamscan -r /path/to/your/directory # Scan directory recursively
💰 Cost of Malware Removal
