How Does Antivirus Work?
Antivirus is software that protects your devices and files from viruses, worms, spyware, ransomware and other malware threats. It runs as a background process and monitors, scans and eliminates cyberthreats. It detects and prevents malware attacks, thwarting attempts to damage or corrupt files on your computer, laptop, mobile device or external devices like hard drives. It also helps identify network security vulnerabilities and offers other features that help keep your devices safe from hacking.

The best antivirus programs have high detection rates, relying on multiple methods to spot new types of malware. The first is signature detection, which looks for unique parts or patterns in the code of a file to identify malware. The more advanced programs use behavior-based detection, which looks at how a program acts to see if it’s mimicking malware behaviour, such as trying to modify system files. Some even rely on cloud integration to get the latest threat intelligence.
Choosing the right antivirus program for your needs depends on the features you need and how much you’re willing to spend. Free antivirus software typically has limited features, but paid packages offer more comprehensive protection with extra safety tools such as a password manager and identity theft prevention. It’s also a good idea to check the company’s privacy policy and whether it shares any of your personal information with third parties. You may also want to look for antivirus that offers on-access scanning, which starts a scan automatically when you open the program or access the protected folders. Scheduled scans are another handy option that remind you to run a scan at regular intervals.
