Abstract
Računalni virus je računalni program koji svojom reprodukcijom može zaraziti računala. On bez znanja ili dopuštenja korisnika računala sam sebe kopira u datotečni sustav. Virusi se najčešće šire s jednog računala na drugo u obliku zlonamjenog koda putem interneta, privitaka elektroničke pošte, diskete, CD, DVD ili USB diska. Neki od najpoznatijih računalnih virusa su računalni crvi i trojanski konji. Računalni crv je program koji širi svoje kopije na druga računala putem mreže te koristi ranjivost sustava kako bi se proširio. Trojanski konj je program koji se pretvara da izgleda bezopasno i predstavlja se kao neka igra ili sadržaj elektroničke pošte, ali najčešće ima skrivenu štetnu funkcionalnost. Da bi se zaštitili od računalnih virusa, na računalo se treba instalirati antivirusna zaštita. Koristi se kao zaštita i uklanja viruse. Kada ga antivirusna zaštita pronađe, šalje ga u „izolaciju“ ili ga potpuno izbriše sa računala. Neki od antivirusnih programa su: Bitdefender, Avast, AVG, Avira i Panda. Testirajući njihovu učinkovitost, postavljeno je na računalo desetak virusa u različite mape. Za testiranje je korištena EICAR datoteka koja omogućuje testiranje bez potrebe korištenja pravog virusa. Bitdefender, Avast i Avira pronašli su svih 10 virusa, Panda je pronašla 9, a AVG nije pronašao niti jedan.

Parallel abstract (English)
A computer virus is a computer program that can infect other computers with reproduction. Without the knowledge or permission of computer users it can copy itself in the file system. The viruses are usually spread from one computer to another in the form of malicious code over the Internet, e-mail attachments, floppy disks, CD, DVD or USB drive. Some of the best known computer viruses are computer worms and Trojan horses. A computer worm is a program that spreads its own copies to other computers over a network and uses system vulnerability to spread. A Trojan horse is a program that pretends to look harmless and presents itself as a game or the content of an e-mail but usually has a hidden harmful functionality. To protect against computer viruses it is necessary to install antivirus protection on a computer system. It is used as a protection and removes viruses. When the antivirus protection finds virus, it sends it in the "quarantine" or completely delete it from the computer. Some antivirus programs are: Bitdefender, Avast, AVG, Avira and Panda. To test their efficiency a dozen computer viruses were places in different folders. For the testing purposes EICAR file that allows testing without using real viruses was used. Bitdefender, Avast and Avira found all 10 viruses, Panda found a 9 and AVG didn't find any
