Malware is short for malicious software, which refers to any intrusive software developed by cybercriminals to steal data and damage or disrupt computer systems. Malware attacks are a common type of cyberattack where malware, normally malicious software, executes unauthorized actions on the victims system. Malware can be installed on a computer without the users consent and can perform malicious actions such as stealing passwords or money. Malware attacks are designed to cause harm or damage to a computer, server, client, or computer network and/or infrastructure without end-user knowledge.
There are many types of malware attacks, including:
-
Viruses: A virus is malicious software attached to a document or file that supports macros to execute its code and spread from host to host. Once downloaded, the virus will lie dormant until the file is opened and in use. Viruses are designed to disrupt a systems ability to operate and can cause significant operational issues and data loss.
-
Adware: 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.
-
Ransomware: Ransomware is a type of malware that encrypts a victims files. The attacker then demands payment in exchange for the decryption key. Ransomware attacks can be devastating for individuals and businesses alike.
-
Trojans: A Trojan is a type of malware that disguises itself as legitimate software. Once installed, it can give attackers access to the victims computer system, allowing them to steal data or install additional malware.
To protect against malware attacks, it is important to install antivirus software and keep it up to date. It is also important to be cautious when opening emails or downloading files from unknown sources.
