Yes, Intego is an excellent Mac antivirus. Intego was originally designed specifically for Mac systems prior to the company developing Windows-based software in recent years.
Intego offers advanced malware detection for Mac systems — both malware scanning and real-time malware detection — as well as a wide range of extra features, such as a smart network firewall and Mac cleanup tools. It’s compatible with macOS Sierra (version 10.12) and higher.
After comparing many Mac-compatible antiviruses, I concluded that Intego is the best, especially for the price (plans start from $1.67 / month).
