Malware, short for malicious software, is a broad term that encompasses any software intentionally designed to cause damage to a computer, server, client, or computer network. Malware infects computers by exploiting security vulnerabilities, such as unpatched software flaws or by tricking users into installing it inadvertently. Common infection vectors include malicious email attachments, infected removable drives, compromised websites that host malware, and files downloaded from untrusted sources.
How it affects your system
Once a system is infected, the malware can perform a variety of nefarious actions depending on its specific type and the intent of its creator. This may include stealing sensitive data like login credentials, financial information, and personal files; monitoring user activity through keyloggers and screen captures; encrypting critical files and holding them for ransom; modifying or deleting files; slowing down or crashing the system; or recruiting the computer into a botnet for further malicious activities. Some of the prevalent types of malware include viruses, worms, Trojans, spyware, adware, and ransomware, each with its own distinct mechanisms for spreading and causing harm. As cyber threats continue to evolve and proliferate, it is crucial for individuals and organizations to maintain robust cybersecurity measures, such as keeping software up to date, using reputable antivirus and anti-malware tools, regularly backing up data, and promoting cybersecurity awareness among users to prevent and mitigate the impact of malware infections.
