VirusScan Enterprise

McAfee also produces an enterprise-level product named VirusScan Enterprise: McAfee has designed this for use on larger networks. It contains features intended to make management of antivirus software on multiple computers easier. Unlike the home-user edition, it consists of a client application - loaded on all networked computers - and a server application, through which the system installs signature and application updates and configures settings for all client programs. Clients can be controlled with the ePolicy Orchestrator, which is a unified console (it can control VirusScan and other McAfee products).

McAfee virus-scanning products did not handle false positives well, repeatedly removing or quarantining known clean files even after the user restores them.

Reviewers have described customer support for McAfee products as lacking, with support staff slow to respond and unable to answer many questions.

McAfee rectified this by removing and replacing the faulty DAT file, version 5958, with an emergency DAT file (version 5959) and has posted a fix for the affected machines in its consumer "KnowledgeBase".
