11.7 MALICIOUS INTENT AND CODE
The word "malicious" means anything that has or shows a desire to cause harm to others.
The term "malicious intent" means an act carried out with the bad intention of causing harm. Malicious codes are
some unwanted programs that cause harm to a computer or affect the data stored on a computer's hard disk or
memory. Different types of malicious codes are computer viruses, worms, trojan horses, etc.
11.7.1 Protection against malicious code
There are many ways to stay safe from malicious codes. They are as follows:
1. Installing and maintaining a good antivirus software and anti-spyware software.
2. Open the links and attachments from unknown emails very cautiously.
3. Always block the pop-up adverts. Most modern browsers have built in pop-up blockers.

11.8 GOOD ETIQUETTE PRACTICES
The word ‘Etiquette’ came from the French word 'etiquette' which refers to label or tag. It is the requirement of

8. Try to avoid any sarcastic jokes while posting on social media, which may hurt someone.
9. We should not post any misinformation.

11.8.1 Good Ethical Practices
Ethics are a set of moral principles that control a person's behaviour or the conduct of an action.
When we relate it to electronic media, all these moral principles are regulated by the use of computers, laptops,
mobile phones, etc. Always follow these 10 commandments while working on a computer.
1. Thou shalt not use a computer to harm other people.
2. Thou shalt not interfere with other people's computer work.
3. Thou shalt not snoop around in other people's files.
