For example, your device can be injected with malware which searches for sensitive information (like passwords or bank account details) and sends it back to the attacker.

How do I get malware

Does a VPN protect from malware
In a way, a VPN doesn’t prevent malware but helps fight it. How? A VPN blocks ports – so that malware can no longer maintain a connection and send commands or collect data. Paired with specific features i.e., CleanWeb™ by Surfshark it will block malicious domains that may lead to a virus infecting your computer.
What happens when malware is installed on a router
There are two most common scenarios after a router gets infected:
- An operator uses your router to create botnets and use them for DDos (distributed denial of service) attacks or similar activities
- An attacker injects malware which compromises your internet traffic
How to know if a device is infected with malware
There are many warning signs which could mean that your device is infected. You should pay attention if:
- Your device starts slowing down for no reason
- You started getting more ads than usual
- Your device starts freezing and crashing
- Odd pop-ups
- Homepage on your browser was changed
- Internet traffic started increasing
- Security software was disabled
- New icons appear on your desktop although you did not install anything
- Unfamiliar error messages start coming
What to do when malware is detected
After you detected malware on your device, you should try backing up your personal files, if it is possible.
Next, disconnect your device from the internet, and do a little research to get a grasp of what kind of malware you have. It is best to do that using another uninfected device. Do not worry if you find it hard to identify a particular malware. There are plenty of tools to remove infections.
Then, scan your device with multiple programs until no malware is found. After your device is clean again, install security software to prevent similar attacks in the future.
