Malware is any malicious software purposefully designed to destroy a computer system, computer server, application, consumer, or user. There are a wide array of malicious software types, such as computer viruses, Trojans, worms, encryption programs, malware, spam, and ransomware. Malware often comes in the form of a program download, email attachment, video file, game file, or program download. Some types of malware are so sophisticated that they are capable of hiding on a computer system without the knowledge of the end-user.
In contrast to the term “malware” (which can be used as well), the “virus” describes an instance of malicious activity. Viruses are malicious programs that do not function in a sense that is compatible with the operations of a PC. True viruses can cause permanent physical damage to a PC. They can also cause information loss, and corruption as well as system instability. Some viruses are designed to delete critical system files and make the PC unable to boot up. Other viruses are designed to exploit security vulnerabilities of a host computer system and steal sensitive personal data.
Many people think that there is only one type of malware, but there are many types. They include: phishing scams, remote-controlcontrol programs, music and video files, games, screen savers, message viruses, keyloggers, dumpsters, and cookies. In addition, some malware can execute other functions, such as changing the homepage, resetting the internet browser’s settings, and changing the computer’s desktop wallpaper. Some viruses corrupt system files and information, create unauthorized user accounts and perform additional functions, such as changing your browser homepage. Malware has been responsible for millions of dollars in losses for corporations, home business owners, and students.
The major problem with malware is that it is often difficult, if not impossible, to detect and remove it. Most malware is self-contained so it won’t cause any problems until you download or install another program that utilizes the same file. As an example, a virus can be on your computer without your knowledge and not affect your computer until you attempt to open an application. Once the virus is installed, it will continue to spread and grow in strength unless you actively monitor your computer and remove the files that it requires to operate.
There are two main types of Malware:
malicious software that spreads through networks and malicious software that damage systems. Network viruses spread by email and can affect many computers on a network. Software that alters or destroys files on a system, including viruses and Trojans, spread through networks by manipulating data in real folders and registry keys. Physical malware, which includes viruses, Trojans, worms, and Trojan horses, are installed on a computer without the permission of the user. Malware can also be downloaded via P2P (peer-to-peer) programs, file sharing programs, email attachments, and instant messages. This can include worms, Trojans, and viruses.
The most common form of Malware is a Trojan horse.
A Trojan horse is a common type of Malware that contains malicious codes that hide on infected files. They are often attached to legitimate files, including music files and email attachments. When opened, these files can run additional harmful codes once the computer is infected. The main intent of the Trojan horse is to steal sensitive information from the computer such as passwords, credit card numbers, and other financial information.
In order to fight malware, it is important to have effective scanning tools that can detect signatures and stay updated on all new versions. It is also important to update the definitions of Malware applications because new Trojans and viruses are released almost daily. It is possible for a Malware application to become invisible but still be able to spread and cause damage. Some types of Malware will require the user to manually remove the application or clean the hard drive. In many cases, these applications cannot be completely removed because they are programmed to run in the system.
- Most malware infections occur when the user downloads an infectious application or through a compromised internet connection.
- Once the infection is in place, it can cause severe problems such as the inability to browse the internet, freeze up the system and data recovery problems.
- It can also affect devices that connect to the internet using Wi-Fi or Bluetooth technology, download files and execute programs without the proper authorization.
- By protecting your computers against malware infections and maintaining an updated Windows version, you can greatly reduce the risk of encountering malware on your computer.
