What is the most dangerous computer virus and why is it so dangerous?
There is no definitive answer to this question as it largely depends on the individual computer system and what it is used for. However, there are some viruses that are considered to be more dangerous than others due to the potential damage they can cause.
One of the most dangerous viruses is known as WannaCry. This virus infected millions of computers around the world and caused billions of dollars in damage. It encrypted data on infected computers and demanded a ransom from the users in order to decrypt it. This virus was so dangerous because it took advantage of a security flaw in Microsoft Windows that had been previously leaked by a group of hackers known as the Shadow Brokers.
Another dangerous virus is known as Stuxnet. This virus was specifically designed to target industrial control systems. It was used to sabotage an Iranian nuclear facility and caused significant damage to the country’s nuclear program. Stuxnet is considered to be one of the most sophisticated viruses ever created and its discovery has led to fears that similar viruses could be used to target critical infrastructure around the world.
These are just two examples of some of the most dangerous viruses that have been discovered. There are many other viruses that are also considered to be dangerous, so it is important to always have up-to-date antivirus software installed on your computer.
