All malicious programs are covered under the umbrella term malware - adware, ransomware, rootkits, spyware, trojans, worms,  and viruses - all are considered malware. It is important that you regularly check your computer for malware, as a malware infection puts your personal data at risk. Keep all system software up to date to reduce the risk of infection.

  • Modified or deleted files

  • New programs or desktop icons that you do not recall installing/creating

  • Programs running without your consent
