Antivirus software

This is a program designed to recognize and fight computer viruses and malicious unwanted programs. In their work, these programs use different principles to find and cure infected files. For the normal operation of a PC, every user should keep an antivirus program updated as the developers of the virus programs are constantly improving them. Users can install antivirus software as part of the software or as a stand-alone application

If the antivirus program detects a virus in the file, it deletes the program code of the virus from it. If treatment is not possible, the infected file is completely deleted.

Device drivers

A driver is a program by which the operating system understands which devices are connected to your computer and how best to communicate with them. Drivers are developed by the manufacturers of these devices (graphics card, network card, sound card, printer, etc.).

For example, you may have purchased an input device, connected it to your computer, and see that the computer does not recognize it. When you install the necessary drivers for the device, the computer will understand what the device is, what it does, and how to use it. The drivers are installed from the disk that comes with the device, or from the official website of the device manufacturer. Or, for example, you bought a sound card, installed it, and noticed that you didn't experience a difference in the sound. In this case, too, you need to install the drivers for that sound card for the device to work properly.

Drivers need to be updated regularly for your computer devices to work properly.
