Users of computer, smartphone, and tablet are faced with an increasingly growing threat due to computer viruses and malware.
There are many types of malware on the Internet that cause direct or indirect harm to individuals and users. These malwares are called Malware.
Malware, which is short form of “Malicious Software”, is the general name of viruses, trojans horses, trojans and other unwanted malicious software.
Malwares are this software having the intentions of doing harm to computer systems, stealing our information, and having other ill-intentions.
We can summarize this malicious software as computer viruses, trojans, worms, spyware and keyloggers.
Computer viruses are software programs that are designed to prevent the operation of the computer, to save, corrupt or delete data, or to cause slowdowns or other problems by spreading themselves over the Internet to other computers. Viruses can enter any computer in different ways and cause undesired results and damages in these computers.
According to the National Institute of Standards and Technology (NIST), the first computer virus called "Brain" was developed in 1986. Two brothers, tired of customers stealing software from their companies, suggested that they have designed in order that it affects the boot sector of disks of the software thieves. When the discs were copied, the virus was also spread.
Trojans are malware that appear to be useful but actually cause harm. How did the Trojan horse in mythology look like a gift and actually carry the soldiers who would invade the city of Troy; these Trojans are computer software that also look like as if they were useful software.
Trojans become active when the file of program, to which they are attached, is run and spread by users copying them. It is not easy to detect them like ordinary viruses. They show their effects after your computer is infected. Trojans can slow down your internet, delete or modify the files on your computer.
