Firewalls are like the security guards of a network—they monitor and control incoming and outgoing traffic based on predefined security rules. Their main job is to protect your network from unauthorized access, cyberattacks, and data breaches.

Signs your device might be infected with malware include:

  1. Sluggish Performance – Apps take longer to load, and the device freezes or crashes often.

  2. Unexpected Pop-Ups – Frequent ads or warning messages, even when you’re not browsing.

  3. High Data or Battery Usage – Malware may run background processes that drain resources quickly.

  4. Programs You Didn’t Install – Strange apps or toolbars appear without your permission.

  5. Browser Redirects – You’re sent to unfamiliar websites or search engines unexpectedly.

  6. Disabled Security Software – Your antivirus or firewall turns off without your action.

  7. Overheating – Continuous heavy processing by malware can make the device hot.

  8. Unusual Network Activity – Large amounts of data being sent/received when you’re idle.

  9. Contacts Receiving Strange Messages – Malware can send spam or phishing links from your accounts.

  10. Frequent Crashes or Error Messages – The operating system or apps behave erratically.

💡 If you notice multiple signs at once, it’s best to disconnect from the internet, run a full antivirus scan, and update your security software immediately to prevent further damage.

I can also give you a step-by-step malware removal checklist if you want to act quickly.
