Mocmex: One of the first serious viruses was made in China where digital frames picked up the virus during the manufacturing process. They passed Mocmex to PCs when connected via USB cable and spread rapidly. With the amount of damage done, security experts rushed to adapt to the situation and insure it would not happen again

MyDoom: Was the fastest email and file sharing computer worm that allowed hackers to access the infected computers hard drive. It is considered by many to be the most dangerous computer virus in history, the Mydoom virus cost around $38 billion worth of damage but also new firewalls to be created

Rabbit (Wabbit): Rapidly duplicated itself so that it would clog and eventually crash the computer system

1971

Creeper Virus : Was the first virus, developed by Bob Thomas and infected Computers that ran the TENEX Operating System. Its purpose was not malicious, as it only was created to prove that programs could duplicate
