What is malware and what are its dangers?
Malware is a term for malicious software, which includes viruses, worms, Trojans, and rootkits. Malware can infect a computer in a number of ways, including downloads from the Internet, opening infected email attachments, and visiting websites that have been compromised by attackers. Once a system is infected, the malware can be used to collect sensitive information, disable security features, or launch attacks against other systems.
Malware is a serious security threat and can result in the loss of sensitive data, system downtime, and damage to reputation. In some cases, malware can even lead to physical damage, such as when a worm propagates through a network and causes equipment to overheat or fail. Because of the dangers posed by malware, it is important to take steps to protect your computer, including installing security software and keeping it up to date.
How does malware get onto my computer?
The short answer is that malware gets onto your computer by you accidentally installing it. That usually happens when you click on a pop-up ad or download a program from a shady website. But there are other ways malware can end up on your machine.
If you have a Windows computer, the vast majority of malware is designed for that platform. That’s because Windows has the largest market share, so it’s the most attractive target for cybercriminals. There are all sorts of malware programs out there, including viruses, worms, Trojan horses, spyware, and adware.
A virus is a type of malware that can replicate itself and spread to other computers. A worm is similar to a virus, but it doesn’t need to attach itself to a program to spread. A Trojan horse is a type of malware that masquerades as a legitimate program. Spyware is a type of malware that gathers your personal information, such as your passwords and credit card numbers. Adware is a type of malware that displays annoying advertisements.
Cybercriminals use all sorts of tactics to get you to install malware on your computer. They might create a fake antivirus program and claim that your computer is infected with a virus. They might embed malware in a file and then send it to you as an email attachment. Or they might exploit a security vulnerability in your web browser or another program to install malware without your knowledge.
To protect yourself from malware, you need to install an antivirus program and keep it up to date. You also need to be careful about what you click on and what you download. Don’t click on pop-up ads, and only download programs from websites that you trust.
