Understanding how malware affects your device is the first step to protecting it.
How to Identify Signs of Malware Infection?
Before you can remove malware, you need to recognize its presence. Common signs of malware infection include:

Step-by-Step Guide to Delete Malware
1. Disconnect from the Internet
To prevent further damage or data theft, immediately disconnect your device from the internet. This stops malware from communicating with its source.
2. Boot into Safe Mode
Safe Mode allows you to run your device with only essential programs. This can prevent malware from loading:
- Windows: Restart your computer and press F8 before the Windows logo appears. Select "Safe Mode with Networking."
- Mac: Restart your Mac and hold the Shift key until the login screen appears.
3. Use an Antivirus or Anti-Malware Program
Run a full scan using a reputable antivirus or anti-malware program. Popular options include:

Review your installed programs and uninstall any that you don’t recognize or remember installing. This can often be done through:
- Windows: Control Panel > Programs > Uninstall a program
- Mac: Finder > Applications, then drag suspicious apps to the Trash

Malware often alters browser settings. Resetting your browser can remove unwanted extensions and restore default settings:
