15 things you should always perform on your pc to stay virus or malware free. Find out these activities:

  1. Make sure to keep your system and apps up-to-date and this will help you to protect your device virus free.

  9. Make sure you choose the unique password for different accounts. Adding the same password to every account can attract hackers. So make sure you choose the secure and strong password that prevents your data from hackers.

  10. Encrypt all sensitive data whenever possible, especially on portable computers and media.
