Introductionmfaff9a0e245c8a64_1528450127855_0Introduction

The teacher initiates a discussion about recognizing the behaviour of the computer which may be the result of infecting it with a computer viruscomputer viruscomputer virus.

The effects of computer viruses:
- deleting data,
- displaying graphics and playing sounds,
- sending unwanted content,
- attacking and breaking into other computers,
- data theft,
- encrypting the data on the hard disc,
- disrupting or disabling work on the computer,
- taking control over the computer,
- creating the network of infected computers.mfaff9a0e245c8a64_1527752256679_0The effects of computer viruses:

Task 1

The students work in the groups of 5. The task of each group is to prepare information about the types of malwaremalwaremalware. The leaders of the particular groups present the effects of their work and formulate conclusions.

Antivirus softwareantivirus softwareAntivirus software is a computer programme used to detect and remove malwaremalwaremalware. It should comprise at leat two basic modules:

- a scannerscannerscanner – which examines the content of discs,
- a monitormonitormonitor – which constantly monitors the operation of the computer.

Antivirus software can also provide firewall, protect mail as well as detect and prevent break‑ins.

The identification of computer viruses by antivirus software is performed by using one of the following methods:

- searching for particular code sequences in a file,
- checking the signatures of files,
- applying heuristics – i.e. trackng the behaviour of a file which is atypical for the operating system.

In order to detect a computer viruscomputer viruscomputer virus by using the first two methods, every antivirus software must have its own virus databasevirus databasevirus database. Antivirus softwareantivirus softwareAntivirus software updates its virus databases constantly by downloading them from the internet.

Task 2

Run the antivirus programme installed on your computer. Check if the virus databasevirus databasevirus database is up to dateup to dateup to date. If not, update it. Scan the resource on the disc specified by the teacher. Read the report after scanning.

A firewall is a software that blocks unauthorized access to the computer. Windows includes a firewall built in the operating system. 

An online virus scannerscannerscanner is one of the modules of an antivirus programme

accessed via a web page.

Task 3

Find an online virus scannerscannerscanner on the internet. Scan with it the disc resource specified by the teacher.

Antivirus preventive measures:

- update software regularly,
- install antivirus softwareantivirus softwareantivirus software,
- activate a firewall,
- use original software,
- do not open files and email attachments from unknown senders,
- protect the computer with a password,
- do not use the administrator account in your everyday work,
- create the backup of important data.

We use the computer both at home and at work. We store on it data which are important for us. They are often very valuable. We should protect them, as we protect all goods that are valuable for us. Remember that there is a group of people in the world for whom your data may also be valuable. They are hackers and your computer connected to the internet may be the target of their attack. In order to protect your computer, use updated antivirus software and follow the principles of antivirus prevention.mfaff9a0e245c8a64_1527752263647_0We use the computer both at home and at work.
