Even trusted websites can get hacked, and criminals can easily spoof emails from your friends or bank. Avast Security alerts you to unsafe websites, blocks unsafe downloads, stops dangerous email attachments, and prevents intrusive web tracking.
Expose the weakest link in your Wi-Fi network
An unsecured Wi-Fi network is an open door to threats. Avast Security scans your entire network and all connected devices for vulnerabilities to help you stop hackers from stealing your personal data.

Does Mac have built-in antivirus protection?
XProtect Apple's basic malware detection is built directly into its Mac OS X operating system. XProtect defends Macs against various types of malware, by scanning downloaded files for signs of infection, but it needs to be regularly updated to recognize new or emerging threats — and it won’t help you if you unwittingly land on an infected or unsafe website.
Digitally signed apps A digital certificate is always seen as proof of a file’s security and a surefire sign that the file contains no malicious code, but cybercriminals can still plant malicious code at the file completion stage, exploit security gaps to sign their malicious files with valid digital certificates, and more.
App Store and Sandbox app security While sandboxing adds another layer of security for Macs, not even the App Store nor sandboxed apps are 100% safe, as highlighted by the attack on the Chinese version of the App Store by the XCodeGhost Virus. Malware authors have frequently found and exploited weaknesses, such as using obscure file formats or large file sizes that the sandbox can’t process, leaving Mac users at risk of infection.
