What Is Malware?Malware is a short form of Malicious Software. Malware is a specifically designed software to affect the performance of a computer and slow down the processing speed of the computer. Malware is an umbrella term used to refer to a variety of forms of hostile or intrusive software.

The Programs that are officially provided by companies can be considered malware when these programs work secretly against the interests of the computer user. An example of this type of malware is the Sony rootkit. In the Sony rootkit, a Trojan was embedded into CDs sold by Sony, which silently installed and concealed itself on the computers of purchasers with the intention of preventing illicit copying; it also reported on users' listening habits and unintentionally created vulnerabilities that were exploited by unrelated malware.
A developer who develops Malware uses a variety of means to spread the malware across devices to infect devices and networks. Malicious software contains a variety of malicious programs that can be easily delivered physically to a system from the use of a USB drive or other means. Malware can also spread across device through the internet through drive-by downloads, this malware if once enter into a system then automatically download the malicious programs into the users' system without their approval or knowledge. These can enter into the user's when a user visits a malicious website, for example. Phishing attacks are another common type of malware delivery; emails disguised as legitimate messages containing malicious links, or attachments can deliver the malware executable to unsuspecting users. Sophisticated malware attacks often feature the use of a command-and-control server that allows threat actors to communicate with the infected systems, exfiltrate sensitive data and even remotely control the compromised device or server.

Malware is designed to fool users, but it also makes fools of security administrators and antimalware products. Some of these evasion techniques rely on simple tactics, such as using web proxies to hide malicious traffic or source IP addresses. More sophisticated threats include polymorphic malware, which can repeatedly change its underlying code to avoid detection from signature-based detection tools; anti-sandbox techniques, which allow the malware to detect when it's being analyzed and delay execution until after it leaves the sandbox, and file-less malware, which resides only in the system's RAM in order to avoid being discovered
