Updated: 10/3/2023

Viruses are things you can get by downloading false programs and all sorts of other things. They steal information from your computer and email people in your email contacts and send the virus to them so over 300 people get the virus. Anti viruses dectect the virus by scanning and a warning will come up saying Caution a virus has been detected or something like that. You never want a virus. Especially Trojan horse or malaware!
