Avast Antivirus Pro includes all the malware-crushing moves of its free little brother, along with premium defenses against Wi-Fi intruders and ransomware.
Your macOS might stop some malware variants, but it can’t help you if you’re already infected. Our antivirus for Mac not only blocks viruses, spyware, Trojans, and other malware in real-time, it also scans your entire Mac for already-hidden threats.
Stop ransomware cold
Avast Security Pro walls off your photos and files from ransomware attack to ensure that none of your most personal memories can be encrypted — or changed in any way — without your permission.
Catch Wi-Fi intruders in the act
Avast Security Pro instantly alerts you when someone joins your Wi-Fi network. This helps you keep hackers out, and stops neighbors from bringing your network to a crawl with their unwelcome video streaming.
