The main purpose of creating of a computer virus is to gain unauthorized access, steal sensitive information, corrupting or destroying data and affects the smooth functioning of the computer. The Nuclear macro virus displayed this message: "And finally I would like to say: STOP ALL FRENCH NUCLEAR TESTING IN THE PACIFIC.". Worms have also underminedIoT securitymeasures. It is because these viruses change their code each time an infected file is executed. "Also, the coding language (Visual Basic, in Microsofts case) is quite simplistic. A computer virus, however, is transferred between hosts much in the same way as a biological virus. Others can be safely removed with reliable antivirus software. They make use of stealth techniques so the users cannot determine the increase in the file code.
