Answer 1

1. Malware infects the system by infiltrating it. It is a kind of software that is used with the intention of destroying the computer and getting all the data from it. It is done by spying and without letting the user know. It attacks the files and vulnerable spots in the system.

2. Malware can spread when there is download of infected software that appears normal. It can also happen if a malicious link was opened. Once in the system, it gets attached to various files and data is overwritten. Similarly it starts to travel in the network and infect all the nodes.

3. Malware works by being installed on the system through malicious downloads or links. It damages the files of the system and then the system itself. The malware code is written specifically to destroy the resources of the system once executed.

4. A virus and malware are somewhat the same. A virus is a special program or software that is able to self-replicate and gets inserted into program codes and affects their operations.

A malware on the other hand is a malicious software that gets installed on a system and damages it.

5. One can manually remove malware by entering the safe mode of the system. In this mode, temporary files can be deleted and using a virus scanner all the malicious software can be found and removed.

6. Very common examples of malware are worms, adware, spyware, and ransomware. Stuxnet, 2010 is a name given to a malware that infected systems in 2010.

7. A malware attack refers to the attack on a system by installing a malicious software on it and not letting the user of the system know about it. The software then gets all the private data from the system and ultimately damages all the files in it.

8. A worm malware works exactly as its name suggests. It spreads from one spot to another by making copies of itself. It can do so without any interaction of humans and without being attached to any software program.

9. Computer viruses tend to harm computers by deleting files, damaging applications and programs, reformatting drives, etc. They can disrupt the performance of the system and cause the system to crash.

10. To protect one's computer from malware, it is important to keep the software updated and use antivirus in the system.

It is also essential that unknown links should not be clicked.

One should check the certification before downloading any software. Firewalls should be used.

11. There are many anti-malware that are considered best. Some of these are Norton, Malwarebytes, and TotalAV. These offer all-around protection and comprehensive features.

12. Worms are self-replicating viruses. They don't need to attach with files and can self-replicate and make copies of themselves. Hence they start to spread in the system from one spot to another and this is how they can slow down any system.

A virus is a software in the form of executable file. It gets attached with another file or program or software in the system and when executed it affects the resources of the system.

Trojan horse is the dangerous kind of infection of the computer. It not only replicates, but also steals important data from the system. It looks like a genuine application and then destroys the programs once on the system.
