Every computer, desktop or laptop, requires an active Anti-Virus license to protect against threats from the Internet.
There are many different companies offering Anti-Virus, and some come free with new computers, but soon the license expires and you start receiving popups throughout the working day.
The Brash recommended Anti-Virus is:
Enterprise grade: Can be centrally managed and cannot be removed by users
Non-intrusive: It does not slow down the computer when running scans or operating in the background
Fixed remotely: If a virus is found, it is notified to us and can be cleared from the admin portal
Cost effective: The monthly cost is less than most major Anti-Virus products
