8 Antivirus Software for Mac: Our Top Picks by Use Case (2026)

Apple provides built-in security features for macOS, including XProtect, Gatekeeper, and automatic malware removal, which contribute to the safety of Macs. However, these protections do not effectively address threats like infostealers, phishing, and adware. For enhanced security, third-party antivirus solutions are recommended. Bitdefender is noted for its strong detection rates and minimal system impact, making it suitable for most users. Intego specializes in Mac-specific threats and is ideal for users focused solely on Apple products. ESET and Trend Micro are recommended for businesses needing centralized management. F-Secure is recognized for its privacy-focused approach, while Norton offers a comprehensive suite of security features. AVG provides free real-time protection suitable for low-risk personal use, but may not be adequate for business needs. CleanMyMac is a maintenance tool rather than a traditional antivirus, focusing on system cleanup and optimization. Users should avoid running multiple real-time scanners simultaneously and ensure they purchase appropriate licenses for business use. It's important to evaluate the necessity of additional features and consider long-term pricing when selecting antivirus software.

How Advanced Browsing Protection Works in Messenger

Advanced Browsing Protection (ABP) in Messenger enhances user privacy by warning users about potentially harmful links shared in end-to-end encrypted communications. It analyzes links using on-device models and a dynamic watchlist of millions of potentially malicious sites, utilizing cryptographic techniques to maintain user privacy. ABP is based on a cryptographic primitive called private information retrieval (PIR), which minimizes the information a server learns from client queries. The system also employs oblivious pseudorandom functions (OPRFs) and manages URL queries through a privacy-preserving URL-matching scheme. The server groups links by domain, allowing clients to request a single bucket for domain-specific path components, and generates a ruleset to balance bucket sizes. To safeguard client queries, AMD's SEV-SNP technology creates a confidential virtual machine (CVM) that processes hash prefixes securely, generating attestation reports for integrity verification. The use of Oblivious RAM and Oblivious HTTP (OHTTP) enhances privacy by preventing exposure of memory access patterns and stripping identifying information from client requests. The lifecycle of an ABP request includes pre-processing phases where the server updates the URL database and computes rulesets, followed by client requests that involve calculating bucket identifiers, sending encrypted requests through a proxy, and checking for unsafe URLs based on server responses.

Meta outlines improved scam protection in Messenger app

Meta has introduced a Safe Browsing feature in Messenger to protect users from harmful links in direct messages, responding to the rise in online scams. The FBI projects online fraud losses in the U.S. to exceed billions from 2020 to 2024, with over a billion expected in 2024 alone. The Safe Browsing feature, launched in October, warns users about malicious links in encrypted messages. Meta has also launched an Advanced Browsing Protection setting that uses a constantly updated database of harmful websites, enhancing user security by combining on-device processing with external data retrieval. This system alerts Messenger users about potential threats before they click on links, allowing them to assess the safety of the links.

Messenger can warn you about sketchy links without knowing what you clicked

Meta has introduced Advanced Browsing Protection (ABP) in its Messenger application to enhance user safety by identifying harmful websites during chats. ABP utilizes a constantly updated watchlist of potentially harmful websites, improving upon the existing Safe Browsing feature. Due to end-to-end encryption, Messenger cannot access message content or links, so ABP uses cryptography and secure computing techniques for link verification without exposing them. When a user clicks a link, Messenger checks it against a blocklist using a privacy-preserving query system. Users can enable or disable ABP in the Messenger app under Settings, Privacy & safety, and Safe browsing. If the option is not visible, users may need to update the app.
