McAfee VirusScan is an antivirus program created and maintained by Intel Security (formerly known as McAfee, Inc., and Network Associates prior to that). McAfee markets VirusScan to home and home-office users; McAfee also develops VirusScan Enterprise for use in corporate environments. The product is not available as a standalone package, but is included in the McAfee VirusScan Plus package or as part of McAfee Internet Security Suite. McAfee also produces a similar product for Mac OS X under the name of VirusScan for Mac. Additionally, BSkyB and McAfee have produced a "Sky Broadband" branded version of VirusScan, offered free to Sky Digital customers upon broadband modem installation.

Features[edit]

The 2010 edition of VirusScan Plus integrates antivirus, firewall and anti-spyware capabilities.

It includes, amongst other things;

  • On-access file scanner (McAfee OAS)
  • Inbound and outbound firewall protection
  • Spyware protection
  • Daily definition updates
  • McAfee X-Ray rootkit detection
  • McAfee SiteAdvisor - displays a safety rating for websites based on tests for evidence of spam, malware and phishing
  • McAfee SystemGuards - monitors a computer for activity that may be caused by virus infection or hacker activity(discontinued: see below)
  • In the upgraded release in February 2010 McAfee discontinued SystemGuards in favor of its Active protection(Artemis), which detects suspicious activity in real-time and contacts McAfee labs to determine whether the file is a threat. Artemis was released around August 2008.[1]

VirusScan Plus 2010 is compatible with Windows 2000, Windows XP, Windows Vista and Windows 7 only.

VirusScan Enterprise[edit]

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).

VirusScan for Mac[edit]

In November 2007 McAfee announced[2] VirusScan for Mac 8.6. (Earlier versions used the name Virex, developed by HJC Software.) The main highlights of VirusScan version 8.6 include:

  • Leopard Compatibility: First version compatible with Mac OS X 10.5 Leopard
  • Universal Binary: First universal binary version in the Virex product line. It will run on both Intel- and PowerPC-based Mac computers natively.
  • On Access scanning: Features true blocking On Access Scanning. It scans every file being accessed from or written to the machine and blocks infections if any. On Access Scanner can be configured to scan on Read Only, Write only or both. It can also be configured to scan files on network volumes.
  • 5301 engine support: The latest McAfee Anti-Virus engine.
  • Apple Mail scanning : It will now scan Apple Mail messages for any infections. This feature is available through both On Demand Scanner and On Access Scanner.

Controversies[edit]

Poor independent test results[edit]

In tests by Virus Bulletin and other independent consumer-organizations, McAfee VirusScan has not fared well, frequently failing to detect some common viruses.[3]

A review of VirusScan 2006 by CNET criticized the product due to "pronounced performance hits in two of our three real-world performance tests"[4] and some users reviewing the same product reported encountering technical problems.[5]

Some older versions of the VirusScan engine use all available CPU cycles.[6]

As of 2009 McAfee virus-scanning products did not handle false positives well, repeatedly removing or quarantining known clean files even after the user restores them.[7]

Customer support criticisms[edit]

Reviewers have described customer support for McAfee products as lacking, with support staff slow to respond and unable to answer many questions.[8][9]

2010 reboot problem[edit]

On April 21, 2010, beginning approximately at 2 PM GMT, an erroneous virus definition file update from McAfee affected millions of computers worldwide running Windows XP Service Pack 3. The update resulted in the removal of a Windows system file (svchost.exe) on those machines, causing machines to lose network access and, in some cases, to enter a reboot loop. 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".[10][11]

2012 update issues[edit]

An August 2012 update to McAfee antivirus caused the protection to become turned off and users to lose internet connections. McAfee was criticized for not notifying users promptly of the issues when they learned about it.[12][13]
