                   The Morris Worm, released in 1988, infected 6,000 computers and almost crashed the early
                   Internet, leading to the creation of the first Computer Emergency Response Team (CERT).

                  To prevent your PC from getting a virus:
                      Download only legal software from trusted sources.

                      Avoid opening emails from unknown senders.
                      Don’t open email attachments unless you know the sender.
                      Don’t download music, programs, or games from unfamiliar websites.
                      Install and use antivirus software on your computer.

                     MALWARE

                  Malware  is  a  malicious  program  designed  to  damage  or  perform  unwanted  actions  on  a
                  computer. The term "malware" combines "malicious" and "software," where "mal" comes from
                  the Spanish word for "bad," making it easier to remember as "badware."
                  There are various types of malware that can harm your computer similarly to a virus, including
                  worms, trojan horses, spyware, ransomware, rootkits, and backdoors.
                  Worms

                  Worms are a type of malware that replicates itself without human intervention. They use significant
                  memory space while replicating, which can cause a computer to slow down, behave unpredictably,

                  and disrupt other tasks. Worms spread from one computer to another through their replication
                  process.
