Many good deeds are easily misused to harm people. With the advent of the Internet, communication between the inhabitants of the entire planet has improved. The speed of information transfer has increased. And malware appeared that could harm many users.
Network viruses are special programs that spread over the Internet. To do this, they use network protocols common to all users around the world. This unification makes possible the proliferation and proliferation of killer programs that destroy useful data. Viruses have been known for a very long time, even if you did not go through them at school in computer science, then in the West famous hackers, virus writers have already appeared: Morris, Mitnick and the like.
Virus propagation paths
Understanding how network viruses spread can greatly protect the user who knows how to defend against them. Knowledge is not only power, but also security. Among the main ways of distribution are:
Even if you have never received mail from strangers, there are still chances of infection.
Email. Through it, viruses come in the form of a letter, then they are automatically launched in Word or the program's own viewer and begin to systematically infect the operating system.
Software obtained via FTP or Web. Many sites have useful programs, utilities, screen savers, movies, music, and other software products that are potentially infected with viruses. When a user downloads such content and then launches it, there is a risk of infection.
Infected sites. Sometimes, when launching the next site, the user observes a picture of how his antivirus does not allow the page to open and writes something like "Page with potentially dangerous content." It is possible that it is infected with a virus that can enter the system.
Self-defense in the network
It is impossible to completely protect the computer and the operating system from the penetration of malicious programs. All that remains for the user is to reduce the potential danger and, if possible, prevent it. There are some ways to do this
There is no 100% protection against viruses, there are just reasonable precautions.
Do not go to pages with potentially dangerous content, content (+18) and links sent by unknown people via ICQ, Skype or Mail.
Do not download programs from unknown sources. There are many proven popular resources on the web that you can use. The rest is at your discretion.
Do not open received mail if it came from unknown addresses.
Install a good antivirus on the system (Kaspersky, GCD, Avast, etc.) and regularly update it, manually or automatically. Do not use pirated versions of such programs. In addition to the fact that it is illegal, it is a shame if the downloaded antivirus is already infected with a virus.
Caution and only caution is the main rule when working, communicating and playing on the Internet. There are many good people in the world and those who just love to do nasty things to their neighbors. The latter should be protected by the above methods.
