The company was founded in 1987 as McAfee Associates, named for its founder John McAfee, who resigned from the company in 1994. McAfee was incorporated in the state of Delaware in 1992. Network Associates was formed in 1997 as a merger of McAfee Associates and Network General. In 2004, a major restructuring occurred. In the spring, the company sold its Magic Solutions business to Remedy, a subsidiary of BMC Software. In the summer[vague] of 2004, the company sold the Sniffer Technologies business to a venture capital backed firm named Network General—the same name as the original owner of Sniffer Technologies. Also, the company changed its name back to McAfee to reflect its focus on security-related technologies.
Among other companies bought and sold by McAfee (formerly known as Network Associates) is Trusted Information Systems, which developed the Firewall Toolkit, which was the free software foundation for the commercial Gauntlet Firewall, which was later sold by McAfee to Secure Computing Corporation. Network Associates, as a result of brief ownership of TIS Labs/NAI Labs/Network Associates Laboratories/McAfee Research, was highly influential in the world of Open Source software, as that organization produced portions of the Linux, FreeBSD, and Darwin operating systems, and developed portions of the BIND name server software and SNMP version 3.
Leading up to the TIS Labs acquisition, McAfee had acquired Calgary, Alberta, Canada-based FSA Corporation, which helped the company diversify its security offerings away from just client-based antivirus software by bringing on board its own network and desktop encryption technologies. The FSA team also oversaw the creation of a number of other technologies that were leading edge at the time, including firewall, file encryption, and public key infrastructure product lines. While those product lines had their own individual successes including PowerBroker (written by Dean Huxley and Dan Freedman and now sold by BeyondTrust), the growth of antivirus ware always outpaced the growth of the other security product lines. It is fair to say that the company remains best known for its antivirus and antispam product lines.
On March 17, 2010, McAfee launched Cloud Secure program, a new service for Software-as-a-Service (SaaS) providers to add additional security to their cloud deployments.

Product reviews[edit source | edit]
Computer Shopper Magazine gave "McAfee Total Protection" a score of 2.5 of 5 stars. They concluded "McAfee Total Protection 2012 has plenty of security tools and protects against malware well enough, but once an infection takes place, it’s not good at removing it. Add in a not-so-intuitive interface, and you have a security suite that best suits security mavens, not casual users."
CNET Magazine gave "McAfee Total Protecion 2012" a rating of 3.5 of 5 stars. They concluded "McAfee has made good products in the past, and it may well do so again. However, the combined performance marks are a horror show, and there are too many inconsistencies throughout the rest of the suite to overlook benchmarks in favor of reputation."
Expert Reviews evaluated "McAfee Security as a Service" and concluded "An easy to use web interface fails to make up for shockingly poor defence against malware."
PC World gave "McAfee Internet Protection 2012" a rating of 3.5 of 5 stars. It finished 14 th in their 2012 "Roundup of Internet Security Suites". They concluded "we find it difficult to give this package a recommendation considering its low ranking." 
NextAdvisor.com gave "McAfee Internet Security 2013" 4 of 5 stars. However, they concluded "with the same old interface and the same old features as last year, McAfee isn't doing much to compete with the other top security software suites, which makes the 2013 version a bit of a disappointment for us."
Neil Reubenking of PC Magazine gave "McAfee Total Protection 2012" a favorable review overall, because the suite "offers a huge array of security-relevant features, among them file encryption, shredding, intruder detection, and more. Its spam filter is accurate and parental control is much improved." However, he added that "its essential antivirus protection doesn't measure up to the very best."
Laptop Magazine gave "McAfee Total Security 2012" 3 of 5 stars. They concluded "McAfee's new security suite introduces several new features, but its performance impact during full scans gives us pause."
Controversies[edit source | edit]
On January 4, 2006, the Securities and Exchange Commission filed suit against McAfee for overstating its 1998–2000 net revenue by $622 million. Without admitting any wrongdoing, McAfee simultaneously settled the complaint, and agreed to pay a $50 million penalty and rework its accounting practices. The fine was for accounting fraud; known as channel stuffing that served to inflate their revenue to their investors.
In October 2006, McAfee fired its president Kevin Weiss, and its CEO George Samaneuk resigned under the cloud of a recent SEC investigation which also caused the departure of Kent Roberts, the General Counsel, earlier in the year. In late December 2006 both Weiss and Samaneuk had share option grant prices revised upwards by McAfee's board. Weiss and Roberts were both exonerated of all wrongdoing from the claims of McAfee in 2009.
In January 2007, under pressure from ex-employees worldwide, several of which backed a class action in the United States, McAfee agreed to honor share options granted, but which are unable to be exercised due to the self-imposed blackout on employee options dealing.
On April 21, 2010, beginning at approximately 14:00 UTC, millions of computers worldwide running Windows XP Service Pack 3 were affected by an erroneous virus definition file update by McAfee, resulting in the removal of a Windows system file (svchost.exe) on those machines, causing machines to lose network access and, in some cases, 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 their consumer knowledge base. The University of Michigan's medical school reported that 8,000 of its 25,000 computers crashed. Police in Lexington, Ky., resorted to hand-writing reports and turned off their patrol car terminals as a precaution. Some jails canceled visitation, and Rhode Island hospitals turned away non-trauma patients at emergency rooms and postponed some elective surgeries. Australian supermarket Coles reported that 10 percent (1,100) of its point-of-sales terminals were affected and was forced to shut down stores in both western and southern parts of the country.
As a result of the outage, McAfee implemented additional QA protocols for any releases that directly impacted critical system files. The company also rolled out additional capabilities in Artemis that provide another level of protection against false positives by leveraging a whitelist of hands-off system files.
In March 2011, a group of "white hat" hackers released a report that they had identified serious vulnerabilities to security at McAfee.com, pointing out flaws that could lead to information disclosure and other issues. 
In August 2012, an issue with an update to McAfee antivirus for home and enterprise computers turned off the antivirus protection and, in many cases, prevented connection to the Internet. McAfee was criticized for being slow to address the problem, forcing network operations to spend time diagnosing the issue.
On June 18, 2013, John McAfee, the founder of McAfee, Inc. released a video making fun of how to uninstall McAfee Anti-Virus on YouTube.
