I like that it works for both Windows computers, Macs, Linux systems etc. There are not too many options out there when you want multiple antivirus programs at once with different features - this one has them all! It's very user friendly also which makes me feel more comfortable about using an Antivirus program than some others have been recently. If looking into buying something new make sure they offer live support so if need be they'll help walk through anything needed or confusion arises along your path (especially after purchasing!). We use this mostly because we're able to run several instances from our home office computer instead having separate devices/computers dedicated only to AV tasks but now other members who work remotely utilize their own personal device(ies) with Avast installed for remote access.
