When a company subscribes to antivirus software, it is unmanaged. The company that creates the software releases regular updates, but users can deny the updates, turn off the virus scanner, or uninstall the software, which can make computers vulnerable to viruses. Managed antivirus software cannot be turned off, so systems are always protected.

Managing antivirus software for dozens of computers at a business can be a challenge if the company does not have a full-time IT staff. A managed antivirus provider can manage all of the software and allow employees to focus on other responsibilities.

Many managed antivirus providers offer their services as a monthly package with a fee per user. This often costs less than a non-managed antivirus solution, especially if the company has a lot of employees and needs to purchase several licenses.
