Malware is any kind of software that a hacker uses to cause harm to a computer or mobile device. Hackers deploy malware to steal sensitive information, disrupt operations, extort money or infiltrate systems.

The most popular malware threats target desktop computers running Windows operating systems, mobile devices running Android or iOS and Internet of Things (IoT) products with Linux-based operating systems. Generally, attackers can gain access to a device with the help of stolen credentials or unpatched system vulnerabilities.

Viruses, worms and Trojan horses are the most common types of malware. Viruses replicate on their own, consuming system resources and causing data loss or damage. Worms, which are similar to viruses, use a victim’s network connection to spread to other devices. Trojan horses pose as legitimate programs like free software updates, games or antivirus programs and install backdoors and other damaging code.

In recent years, ransomware has emerged as one of the most prominent and damaging malware threats. Ransomware encrypts a victim’s data and keeps it locked until the victims pay a ransom to regain access.

Often, the first sign of a malware infection is a slow device or application performance, which results from the malware consuming computer processing power. Another telltale sign is a sudden lack of available storage space, which is often the result of malware downloading additional files. Other indicators include pop-up advertisements, which indicate adware has been installed. The most effective way to prevent malware infections is to practice safe computing and run anti-malware protection on all devices, including IoT and mobile devices.
