McAfee is an American cybersecurity company founded in 1987 by John McAfee, best known for its antivirus and online protection software used by millions of consumers worldwide. Today, the company is headquartered in San Jose, California, and owned by a private investor group led by Advent International. If you have ever wondered who is McAfee and why this name appears on your laptop out of nowhere, this guide covers the full story — from its founding to its current state in 2026.
I have spent years covering cybersecurity topics and testing antivirus software hands-on. What surprised me most about McAfee is how often people confuse the company with its controversial founder. They are two very different stories, and understanding both gives you a clearer picture of whether this antivirus deserves your trust.
What Is McAfee?
McAfee Corp. is a cybersecurity software company that develops consumer antivirus, identity theft protection, VPN, and online privacy tools. It serves over 600 million devices across Windows, macOS, Android, iOS, and ChromeOS platforms. The company’s primary products fall under the McAfee+ brand, which bundles real-time malware scanning, a secure VPN, identity monitoring, and a password manager into tiered subscription plans.
The company started as McAfee Associates in Santa Clara, California, and has gone through multiple ownership changes over nearly four decades. It was publicly traded twice — first in 1992 and again in 2020 on the NASDAQ under the ticker MCFE. Since 2022, McAfee has operated as a private company under the ownership of Advent International and co-investors.

Who Founded McAfee? The Story of John McAfee
John McAfee was a British-American programmer and entrepreneur born on September 18, 1945, in Cinderford, Gloucestershire, England. He moved to the United States as a young man and worked at several technology companies, including NASA’s Institute for Space Studies and Xerox, before founding McAfee Associates in 1987. His breakthrough came when he created one of the first commercial antivirus programs in response to the growing threat of computer viruses spreading through floppy disks.
John McAfee resigned from the company he founded in 1994, selling his remaining shares and cutting ties with the business entirely. After his departure, he pursued a colorful and often controversial life — investing in real estate in Belize, running for the U.S. Libertarian Party presidential nomination twice, and building a large social media following. He had no operational role in McAfee the company for over 27 years.
John McAfee died on June 23, 2021, in a Spanish prison while awaiting extradition to the United States on tax evasion charges. His death was ruled a suicide. The antivirus company issued a brief statement clarifying that John McAfee had not been associated with the brand in any capacity since 1994. This distinction is important — the company’s products, leadership, and operations are entirely separate from the founder’s personal legacy.
McAfee Company History Timeline
1987–1999: Founding and Rapid Growth
John McAfee founded McAfee Associates in 1987, initially operating from his home in Santa Clara, California. The company gained traction quickly as computer viruses became a mainstream concern. The famous Michelangelo virus scare of 1992, which threatened to destroy data on millions of computers, dramatically boosted antivirus awareness and McAfee’s sales. The company went public in 1992 and became one of the early success stories of the cybersecurity industry.
In 1997, McAfee merged with Network General to form Network Associates. This merger aimed to create a broader network security and management company. However, the combined entity struggled with integration challenges and financial pressures throughout the late 1990s.
2000–2009: Network Associates and the Rebrand
Network Associates faced significant accounting issues in the early 2000s, including allegations of channel stuffing — a practice where a company inflates sales figures by pushing excess inventory onto distributors. The SEC investigated, and the company restated several years of financial results. In 2004, the company rebranded itself back to McAfee, Inc., refocusing on its core security products.
During this era, McAfee expanded through a series of acquisitions, purchasing companies like IntruVert (network intrusion prevention), Foundstone (vulnerability management), and SiteAdvisor (web safety ratings). These deals broadened McAfee’s portfolio from a pure antivirus vendor to a multi-product security company.
2010–2020: The Intel Years and TPG Buyout
In August 2010, Intel announced its acquisition of McAfee for approximately $7.68 billion, a deal that closed in February 2011. Intel’s vision was to embed security directly into hardware processors, making McAfee’s software part of the chip itself. The company was renamed Intel Security Group in 2014. However, the hardware-integrated security strategy never gained significant market traction.
In 2016, Intel sold a majority stake (51%) in Intel Security to the private equity firm TPG Capital at a valuation of $4.2 billion — roughly half what Intel originally paid. The company reverted to the McAfee name. Under TPG’s ownership, McAfee refocused on consumer cybersecurity, launching subscription-based products and identity protection services. In October 2020, McAfee returned to the public markets with an IPO on the NASDAQ.
2021–Present: Advent International and Going Private
In March 2022, a consortium led by Advent International, along with Permira, the Canada Pension Plan Investment Board (CPP Investments), GIC (Singapore’s sovereign wealth fund), and the Abu Dhabi Investment Authority (ADIA), completed the acquisition of McAfee for approximately $14 billion. The company was taken private and delisted from the NASDAQ. Consumer-focused operations continued under the McAfee brand, while the enterprise security business was divested separately.
Craig Boundy was appointed CEO in 2024, succeeding Greg Johnson. Under private ownership, McAfee has emphasized its McAfee+ product line, which bundles antivirus, VPN, identity monitoring, scam detection, and personal data cleanup into a single subscription. The company has also introduced AI-powered features including deepfake detection and an advanced scam detector.
Who Owns McAfee Today?
McAfee is currently owned by a private investor consortium led by Advent International, a global private equity firm based in Boston. The consortium completed the acquisition in March 2022 for approximately $14 billion, taking McAfee private. Other major co-investors include Permira, CPP Investments (Canada Pension Plan), GIC (Singapore), and the Abu Dhabi Investment Authority.
As a private company, McAfee no longer publishes quarterly earnings reports or trades on any stock exchange. This shift allows the leadership team to focus on long-term product development rather than short-term quarterly targets. The company’s current strategic focus is on expanding its McAfee+ subscription platform and growing its identity protection services.
McAfee Products and Services in 2026
McAfee’s current product lineup centers on the McAfee+ brand, which comes in four tiers designed for individuals and families:
- McAfee+ Essential: Core antivirus protection, web protection, and a basic VPN with limited server locations.
- McAfee+ Premium: Adds identity monitoring, personal data cleanup, and unlimited VPN access.
- McAfee+ Advanced: Includes identity theft coverage up to $1 million, online account cleanup, and expanded family protection features.
- McAfee+ Ultimate: The top tier, offering $2 million in identity theft coverage, priority customer support, and unlimited device protection across family members.
Beyond the main McAfee+ subscriptions, the company offers standalone tools including McAfee Scam Detector (an AI-powered tool that identifies text message, email, and phone scams), McAfee Safe Connect VPN, and McAfee WebAdvisor (a browser extension that flags dangerous websites). All plans support Windows, macOS, Android, iOS, and ChromeOS devices.
Is McAfee a Good Antivirus?
McAfee earns consistently strong scores from independent testing labs. AV-Test, one of the most respected independent security testing organizations, has awarded McAfee a perfect six-out-of-six rating for protection continuously since mid-2020. AV-Comparatives reported a 99.3% online malware detection rate and a 100% online protection rate in their March 2025 testing cycle. These numbers put McAfee in the same tier as competitors like Bitdefender and Norton.
CNET’s hands-on review in April 2026 noted that McAfee provides solid real-time protection and a clean user interface, but flagged concerns about high CPU usage during full scans (reaching 40–85% in testing) and a first full scan that took nearly five hours. The reviewer also noted that renewal pricing can be significantly higher than introductory rates, which catches many users off guard.
Reddit users in r/antivirus and r/cybersecurity offer a mixed but generally fair perspective. One user noted, “It’s not bad at all. If you look at various views around the web it scores pretty high. It does have a bit of a bad reputation.” The consensus on Reddit is that McAfee works fine as antivirus software, but the user experience — from preinstalled bloatware to aggressive renewal emails — leaves a negative impression that overshadows its actual security performance.
Why Does McAfee Have a Bad Reputation?
McAfee’s reputation issues stem from a combination of historical baggage and ongoing user experience problems. During the late 1990s and 2000s, McAfee software became notorious for being difficult to uninstall, consuming significant system resources, and bundling additional software that users did not ask for. This “bloatware” association has lingered for decades, even though the current product has improved significantly.
The most damaging historical incident was the DAT 5958 false positive in April 2010. A faulty virus definition update mistakenly identified a critical Windows system file (svchost.exe) as malware and quarantined it, causing millions of computers to enter endless reboot loops. Hospitals, police departments, and retail stores running McAfee experienced widespread system failures. The incident became one of the most infamous false positive events in antivirus history.
Today, the most common complaints center on three issues:
- OEM Preinstallation: McAfee comes preinstalled on many HP, Dell, and Lenovo laptops through paid partnership deals. Users who never chose McAfee feel ambushed by the software and its renewal notifications.
- Resource Usage: Background scanning and full system scans can consume significant CPU and RAM, slowing down older or lower-spec machines during active use.
- Renewal Pricing: Introductory rates for the first year are heavily discounted, but auto-renewal at full price ($100+ for some plans) shocks users who were not clearly informed during signup.
The disconnect between strong lab test results and negative user perception is one of McAfee’s most interesting contradictions. The software itself performs well in controlled testing environments. But the user experience surrounding it — from OEM preinstallations to aggressive upselling — has created a brand perception problem that McAfee continues to work against.
Frequently Asked Questions
Is McAfee antivirus good or not?
McAfee earns perfect scores from independent labs like AV-Test (six out of six since 2020) and AV-Comparatives (99.3% detection rate). The software itself provides reliable protection. However, user complaints focus on system resource usage during scans, aggressive renewal pricing, and the bloatware reputation from its preinstallation on HP and Dell laptops.
Is McAfee antivirus still needed in 2026?
If your device runs Windows, macOS, Android, or iOS and you browse the internet, shop online, or use email, antivirus protection remains valuable. McAfee is a legitimate option among top-tier antivirus providers alongside Norton, Bitdefender, and Kaspersky. Whether you specifically need McAfee over its competitors depends on your priorities for features like VPN, identity monitoring, and multi-device coverage.
Why does McAfee come preinstalled on my laptop?
HP, Dell, Lenovo, and other manufacturers include McAfee as part of paid OEM (Original Equipment Manufacturer) partnership agreements. These deals are financially beneficial to the hardware maker and give McAfee access to millions of potential users. The preinstalled version is typically a free trial that expires after 30 days, after which you are prompted to subscribe.
Is McAfee the same as John McAfee?
No. John McAfee founded the company in 1987 but resigned in 1994 and had no connection to it afterward. The company has been owned by Intel, TPG Capital, and now Advent International since 2022. John McAfee died in 2021 while awaiting extradition in Spain. The antivirus company and the founder have been entirely separate entities for over 27 years.
Why does no one like McAfee?
The dislike for McAfee largely stems from three sources: its bloatware reputation from the late 1990s and 2000s, the DAT 5958 false positive incident in 2010 that crashed millions of computers, and the current experience of being preinstalled on laptops without user consent. Many critics admit the software itself has improved but the brand perception remains negative due to these historical issues.
So who is McAfee in 2026? It is a cybersecurity company with nearly four decades of history, strong independent test scores, and a product lineup that has evolved significantly from its early antivirus-only days. The company has survived founder drama, multiple ownership changes, and some of the worst false positive incidents in antivirus history. Today, under private ownership by Advent International, McAfee focuses on its McAfee+ subscription platform with an emphasis on identity protection and AI-powered scam detection.
