Malware is harmful software that can steal passwords, lock your files for ransom, show endless pop-up ads or use your computer secretly. It often arrives through everyday actions that seem harmless.
How malware spreads
- Cracked or pirated software and games downloaded from unofficial sites.
- APK files installed on Android phones from outside the Play Store.
- Email attachments and links from unknown senders.
- Fake “your phone is infected” pop-ups that ask you to install an app.
- USB drives shared between computers.
Protect your computer
- Keep Windows Security (Microsoft Defender) turned on. It is free and built in.
- Install Windows updates regularly.
- Download software only from official websites or the Microsoft Store.
- Avoid cracked software, which often contains hidden malware.
- Scan USB drives before opening files.
Protect your phone
- Install apps only from the Google Play Store or Apple App Store.
- Keep Google Play Protect turned on.
- Check app permissions. A torch app does not need access to your contacts or SMS.
- Update your phone’s software when updates are available.
Signs of infection
- Pop-up ads appearing everywhere, even on the home screen.
- The device is suddenly much slower or the battery drains quickly.
- Unknown apps you did not install.
- Friends receive messages you did not send.
If you suspect malware
- Disconnect from the internet.
- Run a full security scan.
- Uninstall suspicious apps or programs.
- Change important passwords from a clean device.
- If problems continue, seek help from a trusted technician.
Safe habits are the best antivirus. Think before you click, download or install.
