The first computer viruses were created as early as in the 1970s. Starting as pranks, they evolved to become a major threat to computer networks stability worldwide. Biological viruses have always been a potent threat to humanity as multiple historic pandemics have proved. Understanding how they infect, the symptoms they induce, how they spread, and the damage they can cause can help us fight both. Both types of viruses represent just a single type of threat in their respective worlds. Both viruses are just one kind of malware – malicious computer programs. Many infamous cyber outbreaks were caused by computer worms, close relatives of viruses.”]
