We are more cautious about warning messages in physical world to keep ourselves safe from risk of fatality.

In cyber world, we should use the same attitude. If there are system warning messages (e.g. malicious files or threats detected), we have to be vigilant or refer to persons with sufficient knowledge what’s about.

However, be also cautious about fake messages to lure victim installing unnecessary ad-ware or even malware. It’s important to maintain your computing platform with:

  • Latest version with security patches
  • Anti-malware protection from known sources with sound rating from the cyber community
  • Host-based firewall
  • Non-administrative rights in logon session

Further, have home router to act as certain network perimeter between your computer and the untrusted Internet; if you are using mobile device, consider to subscribe cloud based proxy for protection.
