Various types of computer viruses: a threat in the age of the digital world
What are the types of computer viruses? We have already written about the damage caused by computer viruses. In the digital age, where information has become one of the most valuable assets, protection against computer viruses has become an integral part of everyday life. Computer viruses, which are software codes designed to damage or interfere with the normal functioning of computers, can take many forms and effects.
What are the types of computer viruses – Here are some of the most common types of computer viruses:
Viruses
Viruses are one of the most well-known and common forms of computer viruses. They attach themselves to existing programs or files and reproduce when those programs or files are executed. Viruses can cause damage by deleting files, converting data, or even blocking access to the system.
Worms
Worms are autonomous programs that can spread themselves over a network without the need for human intervention. They use vulnerabilities in network protocols to propagate and can quickly spread infection across large networks.
Trojan horses
Trojan horses are a type of virus that hides behind other useful programs. Once installed on a computer, Trojans can create a backdoor for attackers to gain access to sensitive information or control the system remotely.
Spyware
Spyware is designed to collect information about users without their knowledge. They can log keystrokes, track web browsing, steal passwords and other sensitive information that is then used for fraud or abuse.
Advertising software
Advertising software, or “adware,” displays intrusive advertisements on a user’s computer. This can slow down the system and interfere with the normal use of the computer.
Phishing programs
Phishing programs are designed to harvest sensitive information, such as passwords, credit card numbers, etc., by impersonating trustworthy websites or sending fraudulent e-mail messages.
Each of these types of computer viruses poses a serious threat to data security and user privacy. To protect yourself from these threats, it’s important to install anti-virus software and update your programs and operating system regularly. You should also avoid opening dubious websites and downloading files from unreliable sources. Remember that the best protection against computer viruses lies in an educated user.
