儘管現階段Mac電腦裝上防毒軟體的實際功用並不算大，不過對很多人來說盡量能多層防護的話會更好些，其實我覺得要是Mac電腦的防毒軟體能辨識、掃除對於Windows系統的病毒的話會更好（因為很多不針對Mac但會危害PC的病毒常不小心轉送出去）。如果你在工作上不允許任何差錯、希望能更嚴密的防患於未然，可以試試看本文所介紹的Sophos Anti-Virus for Mac Home Edition免費防毒軟體。
Sophos Anti-Virus for Mac Home Edition免費防毒軟體可以檢測、清除或隔離Mac與Windows系統上常見的病毒、木馬、蠕蟲與各類惡意程式，除了免費使用之外整個軟體的設計相當簡單、不擾民，安裝好之後幾乎不用做什麼設定，Sophos防毒軟體會在背景中自動執行、監測，如果有抓到疑似病毒時才會跳出來提醒我們。
