Protecting Computer Systems With Antivirus Software Zaštita računalne sustave s protuvirusni softver

Computers all over the world are susceptible to increased virus threats these days. Računala cijelog svijeta su osjetljiv na povećanu prijetnje virusa ovih dana. Preventing viruses from attacking computers has nearly become an obsession for anti virus software developers. Izbjegavanje virusa iz računala napadaju ima skoro postati opsesija za anti virus softverskim razvijateljima. Even large corporations like Microsoft have been exposed to virus attacks. Čak i velikim korporacijama kao što su Microsoft je izložena napadima virusa.

Before the advent of internet, the spread of computer viruses was largely limited to manual transmission through floppy disks. Prije nego što je pojava Interneta, širenja računalnih virusa je u velikoj mjeri ograničene na ručnim prijenosom putem diskete. Hence it was much easier to detect and eliminate viruses before they could do any large scale damage to a computer system. Stoga je mnogo lakše otkriju i eliminiraju viruse prije nego oni mogli učiniti bilo koju štetu velikih razmjera na računalni sustav. All that was required was a scan of the floppy disk by antivirus software before copying the files from it to the computer. Sve što je potrebno je skeniranja na disketu koju protuvirusni softver prije kopiranja datoteka iz nje na računalo. The spread of the virus to other computers was thus slow. Širenja virusa na druga računala bila tako spora.

The rising popularity of internet has changed the situation completely. U diže popularnost na internetu je promijenila situaciju u potpunosti. The virus can now spread very fast from one system to another through the internet as the medium. Virusi mogu sada proširila se vrlo brzo s jednog na drugi sustav putem Interneta kao medija. The virus could spread through various means: emails and their attachments, instant messages, peer to peer to sharing of files, software downloads etc. They can spread automatically without any manual intervention and can enter the system in multiple ways, exposing the vulnerability of the system. Virusi mogla širiti kroz razne načine: e-poruke i njihove privitke, trenutačnih poruka, ravnopravnih članova za dijeljenje datoteka, download softver itd. Oni mogu širiti automatski bez ručne intervencije i mogu ući u sustav na više načina, otkrivanju ranjivosti u sustava. With the convergence of technologies like computers and communication through mobile devices, the threat of computer viruses is raising by the day. Uz približavanje tehnologije poput računala i komunikacije putem mobilnih uređaja, opasnost od računalnih virusa je podizanje iz dana u dan.

Protecting the computer from viruses Zaštita računala od virusa

The antivirus software technology has kept pace with the various types of virus threats and has become inseparable part of a computer system today. U protuvirusni softver tehnologija je zadržao tempo s različitim vrstama virusa i prijetnje je postala nerazdvojni dio jednog računalni sustav danas. The antivirus software products can thwart attempts by viruses to enter a computer system through emails, internet browsers, file servers and other desktops in a network. U proizvode protuvirusni softver može suprotstaviti pokušajima od virusa za otvaranje računalnog sustava kroz e-poštu, internet preglednici, datoteke poslužitelje i drugih računala u mreži. They also have a centralized system of deploying the software as well configuring it to a particular system and updating of the software. Oni također imaju centralizirani sustav distribucije softvera kao i konfiguriranju da se određeni sustav i ažuriranje softvera.

The following lists some of the steps a computer user must take for protection against virus threats. Sljedeći navodi neke od koraka računalo korisnik mora poduzeti za zaštitu od virusa prijetnje.

1. The first step in protecting your computer system against viruses is to evaluate the current antivirus software that is being used to find out if it is adequate and covers all possible forms of threats. Prvi korak u zaštiti svoje računalo od virusa je sustav za procjenu trenutne protuvirusni softver koji se koristi da biste saznali ako je primjerena i pokriva sve moguće oblike prijetnji. A computer network with desktops and servers with connection to the internet requires anti virus software with many features like a firewall, antivirus, content filtering and spyware detection. A računalna mreža s računala i poslužitelja s priključkom na Internet zahtijeva anti virus softver s mnogim značajkama kao što su firewall, antivirusni, filtriranje sadržaja i spyware detekcije. All the components of the system like desktops, server, gateway etc. need to be protected from external threats. Sve komponente sustava kao i stolna računala, poslužitelja, gateway i sl. moraju biti zaštićene od vanjskih prijetnji.

2. The antivirus software needs to be regularly updated against new virus threats emerging everyday. U protuvirusni softver treba biti redovito ažurirana protiv novih virusa prijetnje svakodnevnom nastajanju. The reputation of the company that developed the antivirus software is important in this respect. Ugled tvrtke koji je razvio protuvirusni softver je važno u tom pogledu. The software should have real time scanning feature that automatically starts scanning the files in the computer as well as any incoming messages, software etc. when the system is booted up. Softver bi trebao imati mogućnost skeniranje u stvarnom vremenu koji se automatski pokreće skeniranje datoteka na računalu, kao i bilo koji dolazne poruke, softvera i sl. kada se dignete sustav.

3. All new programs should be compulsorily scanned irrespective of their place of origin. Svi novi programi trebaju biti skenirane compulsorily bez obzira na njihovu rodnom kraju.

4. Attachments to emails or instant messages in any form from unknown sources should not be opened without ascertaining that they are free from virus. Prilozi za instant poruke e-pošte ili u bilo kojem obliku iz nepoznatih izvora ne bi trebao biti otvoren bez potvrđivanje da su slobodni od virusa.

5. Taking regular backups of important files in the system will ensure quick recovery of the system in case of a virus attack. Uzimajući redovite sigurnosne kopije važnih datoteka u sustavu će osigurati brz oporavak sustava u slučaju virus napada.
