Malware is a term used to describe any software that is intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the users computer security and privacy. Malware is developed as harmful software that invades or corrupts your computer network. The goal of malware is to cause havoc and steal information or resources for monetary gain or sheer sabotage. Malware can be classified into one or more sub-types, including:
- Computer viruses
- Worms
- Trojan horses
- Ransomware
- Spyware
- Adware
- Rogue software
- Wiper
- Keyloggers
Malware can be used broadly against government or corporate websites to gather sensitive information or to disrupt their operation in general. It can also be used against individuals to gain information such as personal identification numbers or details, bank or credit card numbers, and passwords. In addition to criminal money-making, malware can be used for sabotage, often for political motives.
The two most common ways that malware accesses your system are the Internet and email. Malware can take many forms, including viruses, worms, trojan horses, ransomware, and spyware. Adware is malicious software used to collect data on your computer usage and provide appropriate advertisements to you. While adware is not always dangerous, in some cases, adware can cause issues for your system. Adware can redirect your browser to unsafe sites, and it can even contain Trojan horses and spyware. Additionally, significant levels of adware can slow down your system noticeably.
To prevent malware infections, it is recommended to install antivirus software and keep it up to date. Users can also avoid clicking on suspicious links or downloading attachments from unknown sources. It is also important to keep software and operating systems up to date with the latest security patches.
