to slow down your hard-drive, hack your personal info, or just to do so. It is illegal. And they can completely crash your hard-drive.
There are all sorts of reasons, however, the most common is because some viruses can track what you do- online or offline. If you enter your bank account details in somewhere, for instance, the person who made the virus can see what you put, and can therefore be able to steal from it. Other reasons include, but are not limited to:
'Posing' as you on popular Instant messaging sites & email providers, so they can force people to also develop the virus;
Crashing people's systems
Deleting important information.
Some viruses were created as experiments.
cause there x-boxes have crashed and they have nothing better to do than make us completley miserable.
Malicious (evil) people create computer viruses.
Computer viruses can be created to steal malware, information or anything that can be very valuable. Some people thing that people are meanies and will create viruses on purpose like apple employees and then they will create viruses for pc's so that people will go purchase a mac and vise versa but apple is much better at it if it truly does happen.
like we need more viruses
Not sure if you mean to question the virus in biology or in computer software, however I shall answer both questions. In biology viruses are actually used to combat new diseases and create cures. The can actually be used also for technology where a virus was actually used in a battery for-to power a device similar to a computer. In computer software, sometimes people create viruses as almost a hobby. They are they hackers, the thieves, or whatever you want to call them, of the CyberWorld. Viruses can be used to steal information and identities. Viruses have actually been used also to download illegally. The unknown side of viruses is that a good portion of them are actually created accidently. These are most common as boot-sector viruses. However, then can entail other forms as well. Usually they pop up when there are compatibility issues and the computer crashes. - So to answer, sometimes people create viruses for illegal purposes or sometimes they are created by accident.
They are evil
uncareful people
100%
People are trolls
The people who made computer virus are unkown.
It is generally considered unethical because computer viruses and other malicious programs harm other people's computers, which are other people's property. They also can violate other people's privacy, and also that you are accessing their computer without their permission.
There are hundreds of thousands of viruses out there (if not millions) and they often designed for different objectives. Most of them fall under the following categories: *To take control of a computer and use it for specific tasks *To generate money *To steal sensitive information (credit card numbers, passwords, personal details, data etc.) *To prove a point, to prove it can be done, to prove ones skill or for revenge purposes *To cripple a computer or network By: Tasmanian Devil & Angel
Only possible positive effects are software companies that can kill viruses are very profitable and create jobs for bright young people.
