Antivirus software first showed up in 1971 with Ray Tomlinson’s Reaper, the earliest known program built to hunt down and remove the Creeper virus.
Who created first antivirus software?
Andreas Lüning and Kai Figge deserve that credit—they launched the first commercial antivirus in 1987 through G Data Software AG in Germany.
Unlike the Reaper, which was more of an experimental self-replicating cleanup tool, their software was built specifically to shield PCs from viruses. That shift—from academic experiments to actual security products—happened right as personal computers exploded in popularity during the late 1980s and early 1990s.
When was McAfee Antivirus introduced?

When was first computer virus?
The Creeper virus appeared in 1971 on DEC PDP-10 computers running TENEX.
Bob Thomas at BBN Technologies cooked it up as a harmless experiment. All it did was flash “I'M THE CREEPER: CATCH ME IF YOU CAN” on screens. Sure, it wasn’t meant to cause damage, but it proved self-replicating code could travel across networks—and that idea later shaped both viruses and antivirus tools.
What was the first anti virus?
The Reaper, built by Ray Tomlinson in 1971, is generally recognized as the first antivirus program because it actively hunted down and deleted the Creeper virus.
Where the Creeper just copied itself, the Reaper was programmed to find and remove infected files. It ran on ARPANET—the early internet—and showed that computers could fight back automatically. That principle still drives antivirus technology today.
What was the first computer antivirus?
The Reaper in 1971 holds that title, created by Ray Tomlinson to wipe out the Creeper virus.
It patrolled ARPANET-linked PDP-10 machines, sniffing out and deleting infected files. It wasn’t sold in stores, but it proved the concept of automated threat removal. That foundation eventually grew into the antivirus software we depend on now to block malware and other cyber nasties.
Who is McAfee owned by?
As of 2026, McAfee trades publicly under the ticker MCAF and operates independently.
It split from Intel in 2016, went private in 2020 under TPG and Intel Capital, then returned to the public market in 2022. For the freshest details on ownership and finances, check the latest filings at SEC.gov.
Who is known as father of antivirus?
John McAfee usually gets that label for founding McAfee Associates in 1987.

Is McAfee an example of antivirus?
Absolutely—McAfee is a classic antivirus example, offering real-time scans, malware detection, and removal tools.
Products like McAfee Antivirus Plus and McAfee Total Protection block viruses, ransomware, spyware, and phishing attempts. It’s one of the oldest names in the business, though newer players have reshaped user preferences and market rankings over the years.
Do computer viruses still exist 2020?
Self-spreading viruses like the 1980s classics are basically gone by 2026, but the word “virus” still gets tossed around for all kinds of malware.
Today’s threats lean toward ransomware, trojans, spyware, and fileless malware that don’t behave like the old-school replicators. Security companies still call anything malicious a “virus,” even if it doesn’t spread the way the Creeper or Brain did back in the day.
What is the first computer in the world?
The ENIAC (Electronic Numerical Integrator and Computer) debuted in 1945 at the University of Pennsylvania.
This beast weighed over 30 tons, stuffed with 17,468 vacuum tubes, and crunched numbers for the U.S. military during World War II. It ran decimal math instead of binary, but its programmable design laid the groundwork for every computer that followed. Constant maintenance and sky-high power bills were just part of daily life back then.
Do viruses have a DNA?
Most biological viruses carry DNA or RNA as their genetic code, but they aren’t considered living things.
Computer viruses borrow the name because they behave like parasites—copying themselves and attaching to other files. Yet unlike real viruses, they don’t contain any genetic material at all. It’s purely a metaphor based on how they spread and latch onto hosts.
What is the best antivirus for PC?
As of 2026, Bitdefender, Norton, and Kaspersky top most “best antivirus” lists for solid PC protection.
All three deliver real-time scanning, ransomware shields, and web security. Independent labs like AV-TEST and AV-Comparatives regularly rank them on speed and detection. Pick the one that fits your budget, system specs, and threat priorities.
Why is McAfee wanted?
As of 2026, John McAfee isn’t wanted by any authorities, though his past included legal run-ins.
In 2012, Belize police briefly wanted him for questioning in a neighboring murder case, but no charges ever stuck. Later, Spanish authorities arrested him in 2020 on U.S. tax-evasion charges; he died in custody in 2021. The company itself operates legally and has no active warrants.
Is McAfee owned by HP?
Nope—HP doesn’t own McAfee anymore as of 2026.
HP sold its 51% stake back to Intel in 2013 and fully exited the security business. McAfee has been independent since its 2022 IPO. For the latest ownership details, skim the most recent corporate filings.
