Viruses
Viruses
Viruses, are something that your computer can get if your not careful what websites you go on, or what you download! They can be very harmful for your computer and could stop them working all together!
Three types of Viruses we are going to look at:
Email viruses
Worms
Trojan horses
Email Viruses
Email viruses are easily sent around and given simply by sending an email. This happens, when one person sends, an email to another of which contains a virus. They often have a subject of which may make you read it like "Hey Dude", or "Omg, you'll never guess what i was told yesterday!"
| Worms!! |
A computer worm is a self-replicating malware computer program, which uses a computer network to send copies of itself to other nodes (computers on the network) and it may do so without any user intervention. This is due to security shortcomings on the target computer. Unlike a computer virus, it does not need to attach itself to an existing program. Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer.
Trogan Horses
A Trojan horse, or Trojan, is a destructive program that masquerades as a benign application. The software initially appears to perform a desirable function for the user prior to installation and/or execution, but (perhaps in addition to the expected function) steals information or harms the system.Unlike viruses or worms, Trojan horses do not replicate themselves, but they can be just as destructive.
