maximizing the user's personal safety and security risks to private

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.

4. Don’t post any personal information online – like your
address, email address or mobile number.
Think carefully before posting pictures or videos of
yourself. Once you’ve put a picture of yourself online most
people can see it and may be able to download it, it’s not just
yours anymore.
Keep your privacy settings as high as possible.
Never give out your passwords.
Don’t befriend people you don’t know.
Don’t meet up with people you’ve met online. Speak to your
parent or carer about people suggesting you do.

5. 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.

14. VIRUS
Software that can replicate itself and spread to other computers or are
programmed to damage a computer by deleting files, reformatting the hard
disk, or using up computer memory.
There are two types of computer viruses 'parasitic' and 'boot' virus.
A Parasitic virus attaches itself to other programs and is activated
when the host program is executed. It tries to get attached to more
programs so that chances of getting activated is more. It spreads to
other computers when the affected programs are copied. 'Jerusalem'
and 'Datacrime' are parasitic viruses.

15. 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.
