ONLINE SAFETY

Web safety, or online safety or Internet Safety is the knowledge of maximizing the user's personal safety and security risks to private information and property associated with using the internet, and the self-protection from computer crime in general.

As the number of internet users continues to grow worldwide, internet safety is a growing concern for both children and adults. Common concerns regarding safety on the internet include: malicious users (spam, phishing, cyberbullying, cyberstalking etc.), websites and software (malware, computer viruses, etc.) and various types of obscene or offensive content. Several crimes can be committed on the Internet such as stalking, identity theft and more.

Remember that not everyone online is who they say they

are.

Think carefully about what you say before you post

something online.

Respect other people’s views, even if you don’t agree with

someone else’s views doesn’t mean you need to be rude.

If you see something online that makes you feel

uncomfortable, unsafe or worried: leave the website, turn

off your computer if you want to and tell a trusted adult

immediately.

A Boot virus is designed to enter the boot sector of a floppy disc. It works by replacing the first sector on the disc with part of itself. It hides the rest of itself elsewhere on the disc, with a copy of the first sector. The virus is loaded by the computers built-in start-up program when the machine is switched on. The virus loads, installs itself, hides the rest of itself and then loads the original program. On a hard disc, virus can occupy DOS boot sector or master boot sector.
