Malware can be described as any malicious software purposely designed to harm a computer system, application, server, consumer, or computer network. There are a wide range of malware types available, including worms, Trojan horses, malware-generated applications, encryption viruses, ransomware, fake antivirus scans, and fake online security scans. Malware may vary in its objectives and effects but typically works to gather personal information and credit card numbers by capturing keystrokes, viewing bank or gaming accounts, and leaking vital information through compromised internet connections. Malware often enters computers through Trojans, malware-generated email attachments, phishing, and exploited websites. It may also be downloaded automatically through freeware and shareware applications.
With the rise of smartphone apps, more devices are connecting to the web via mobile apps. As a result, malware has become even more common. Malware typically comes on the phone without the users’ awareness or permission. Malware can come from any number of sources, including freeware and shareware programs, games, instant messaging, and email attachments. Ransomware, the name for a type of malware that demands money for the removal of infected files, is particularly dangerous because it allows hackers to access and use confidential information.
Two of the most common types of malware are adware and worms.
Adware comes on the screen with a preinstalled add-on or bundled email attachment and is often used to track user behavior. Worms are commonly spread via freeware programs and networks. Examples of worms include Trojans, backdoor programs, and worms created by scanning email programs.
Firewalls can prevent malicious software from accessing your network, but they can also be used to mask malware on your devices. Most modern firewalls are updated via the internet, making it easy to keep malware running on your network. Some devices, such as USB drives, webcams, and phones that run web-based applications, can also be updated via the internet. To protect your network, install a firewall on all of your devices.
Viruses are another type of malware that can infect devices.
Common types of viruses include spyware and adware that hide on your devices and send information back to their authors. Some malicious code can create a Trojan horse, which can affect your system in a number of ways, including stealing your bank accounts or credit card information.
Distributed Denial of Service (DDoS) is a type of malware that attacks computers that are connected to the internet. These malware programs are typically distributed through spam. Common methods of DDoS include sending multiple attacks on one system, or sending spoofed messages that attempt to overload the network’s server. Other ways that DDoS works are through spamming network servers, crashing sites, and changing the web server’s configurations.
When an unknown user gains access to your computer systems through malware, they have the ability to run programs and do things without your consent. They can modify settings, delete files, and perform other activities. The best defense against malware is not only preventing it from gaining access to your computer systems, but by removing any malware before it is allowed into your computer. To remove malware, use a trusted anti-malware program that has a built-in network scanner and spyware removal features. To get rid of Trojan horses, scan your PC with the program’s anti-malware program.
- Malware can be a serious threat to both small and large businesses and should be taken seriously.
- To protect yourself from spyware and other malicious software that arrive on your network, be sure to regularly scan your system for infections.
- In addition to installing anti-malware programs that detect Trojan horses and other malware, you should also keep your computer updated with the latest security and anti-spyware updates.
- By being informed about current threats and implementing preventive measures, you can help ensure that your network remains secure.
