What Is Antivirus and How Does It Work?
Antivirus is software that searches, detects, prevents and removes malware like viruses, worms and spyware from your computer or network. It acts as the first line of defence in a cybersecurity plan and works best when used alongside firewall integration, multi-factor authentication and employee awareness programs.
The majority of antivirus packages work by scanning files and applications that come into your system with a database of known malware signatures. Then it looks for patterns and identifies suspicious behaviours in order to quarantine or eliminate the threat. This method of detection is called signature-based protection and it’s important that your antivirus receives regular updates to keep up with the latest threats.
However, new malware attacks are continually emerging and hackers are finding ways to bypass security systems. This is why it’s recommended that you look into options that offer multi-layered protection to provide a more comprehensive level of defence against cyberattacks.
Antivirus software protects against various forms of malicious software, such as adware, spyware, ransomware and trojans. It also provides other security features such as anti-spam, parental controls, camera and password protection to improve overall safety from internet threats. Some of the more advanced anti-virus software even comes with encryption capabilities and rollback functions to get your data back to a pre-attack state after a cyber attack occurs. Regardless of the type of antivirus you choose, it’s crucial that you ensure your anti-virus software is efficient and up to date to avoid slowing down your machine or being blocked by security systems.
