Do we really need Antivirus to protect our system?

Yes, Antivirus protection software detects and removes viruses from computers, and protects against a number of threats, including malicious software, such as keyloggers, browser hijackers, worms, rootkits, spyware, adware, botnets, ransomware, and File-less malware.

How does Antivirus Work?

Antivirus software typically runs in the background. It processes and scans computers, servers, or mobile devices to detect and prevent the spread of malware. Many antivirus programs include Critical threat detection and protection to protect against potential vulnerabilities, & system scans that monitor device and system files.

The most tried and tested method used to combat viruses and other malware is signature-based detection. It looks for the specific digital code of a virus and if spotted, deletes it.

Here is the reason  why you  need Antivirus for Android Devices

Antivirus Protection for Android devices is deemed to be less secure since they run on open-source code. It means an owner can play around with the settings to adjust them to their liking. They also source apps from developers. Doing so causes a weakness in the device and makes them vulnerable to malware. Though Android devices don't get traditional viruses, they get other malware. This malicious software can be made to secretly control the mobile device and thus stealing your private data.
