Bernardo Quintero makes the service’s early years, unlikely growth and 2012 Google acquisition vivid. The book is worth reading for cybersecurity professionals, technology historians, entrepreneurs and curious general readers—provided they do not expect a detailed history of VirusTotal under Google.
What exactly is Infected?
Bernardo Quintero’s Infected: From Side Project to Google: The Journey Behind VirusTotal is a founder memoir, entrepreneurial narrative and piece of cybersecurity history. The English edition was translated from Spanish, whose original title is Infectado: Del Spectrum a Google, el camino de un emprendedor accidental. The English-language catalogue record describes an approximately 350-page paperback published in January 2025; listings differ by a day, giving January 15 or 16. Its ISBN-13 is 978-84-09-68366-6 (9788409683666 without hyphens), and its ISBN-10 is 8409683660. See the bibliographic record at Todostuslibros and the reader listing at Goodreads.

That edition detail matters: readers searching only for Infected can easily encounter unrelated fiction or medical nonfiction, or the Spanish edition. The subtitle and ISBN identify the VirusTotal book. It is also not an official Google corporate history. It is one founder’s account, shaped by memory, access and the decisions about what to include.
The story Quintero tells
From Spectrum experiments to security work
The narrative begins with Quintero’s childhood fascination with computers, including programming and experimentation during the ZX Spectrum era. His curiosity about viruses and malware leads into the work that became Hispasec Sistemas, the Spanish security company he helped establish.
The practical problem behind VirusTotal
VirusTotal emerged from a practical security question: how could researchers check a suspicious file against many antivirus engines without obtaining and maintaining every product themselves? Quintero’s answer was a service that submitted files and other indicators to multiple engines and returned their results. The book’s chapters on “The Origin of the Idea” and “The Birth of VirusTotal” are its clearest account of that transition from side project to widely used platform.
From 2004 launch to global resource
Contemporary reporting places VirusTotal’s launch in 2004 through Hispasec. The service grew beyond a convenient scanning website into infrastructure used by malware hunters, incident responders, security vendors and threat-intelligence teams. An account of the early years is also available in contemporary reporting by El País.
Why VirusTotal mattered
VirusTotal’s importance is not that it supplies a magical yes-or-no malware verdict. Its contribution is aggregation: many detection engines and analysis systems can be consulted through one service, giving researchers comparative visibility and a shared place to examine files, URLs, domains, IP addresses and related indicators.
- Multi-engine context: differing labels can reveal that a sample is newly detected, disputed or classified differently by vendors.
- Research workflow: investigators can pivot from an indicator to related observations and historical context.
- Collaboration: a common service helps researchers, responders and vendors discuss the same artifacts.
- Threat intelligence: accumulated observations make the platform useful for tracking campaigns and infrastructure, not merely checking one file.
A detection is not proof that a file is malicious, and a clean result is not proof that it is safe. False positives, missed detections, evasive samples, reputation systems and the context of the submission all matter. That distinction is important for readers who know VirusTotal only as a public scanning page, and it is one reason the book should be judged partly on how well it explains institutional significance to non-specialists.
The acquisition drama
The acquisition is more than the memoir’s dramatic finale: it tests what happens when a small, community-oriented security service becomes strategically valuable to a major technology company.
According to the account discussed in the SecurityWeek review, CrowdStrike founders Dmitri Alperovitch and George Kurtz visited Málaga while pursuing VirusTotal. Google’s interest was reportedly advanced by Google Threat Analysis Group founder Mike Wiacek, who took the matter to Larry Page and Sergey Brin. The review describes Google moving quickly and giving the founders a short window to respond. These colorful negotiation details belong to Quintero’s memoir and its review; they should not be read as independently verified terms of an acquisition.
Rank #2
- Used Book in Good Condition
Google acquired VirusTotal in 2012. The public record confirms the transaction and the service’s Málaga origins, but Infected is most valuable where it shows the people, uncertainty and timing behind the decision. It asks readers to consider why Google was attractive, what the founders hoped to preserve and how an independent Spanish startup could fit inside Google without losing its usefulness to the security community.
What the book does especially well
A personal voice
Quintero writes about computers, business and security through lived experience rather than abstract startup mythology. Humor, personal anecdotes and interpersonal drama make the technical history accessible. The result feels like a story about people making imperfect decisions, not a retrospective in which success was inevitable.
Humanizing early security entrepreneurship
The memoir gives Spanish technology entrepreneurship a setting often missing from Silicon Valley-centered histories. It shows how experimentation, persistence and local relationships can produce infrastructure with worldwide consequences.
Showing resistance and uncertainty
The review highlights the book’s willingness to describe early objections to sharing data and vendor friction, including an anecdote in which Trend Micro temporarily withdrew its engine and later sought to return. That is an account attributed to the author, not a separately established corporate record, but it illustrates the institutional problem VirusTotal had to solve: competing vendors had to participate in a system whose value depended on comparison.
Where Infected falls short
The Google-era gap
The largest limitation is the relative lack of detail after the 2012 acquisition. The book reportedly says little about integration, internal culture, commercialization, governance, the founders’ and staff’s later roles, or how VirusTotal’s public-facing identity fit within Google Cloud. It does not fully answer whether Google changed the service’s mission, how decisions were made after the sale or what trade-offs followed.
That silence may reflect the author’s chosen timeline, privacy considerations or corporate communications limits. The book does not establish which explanation is correct, so readers should treat the omission as a boundary of the account rather than an accusation.

One founder’s perspective
A memoir can be candid while still being selective. Quintero can describe his own decisions and relationships in unusual detail, but a complete history would also require perspectives from co-founders, employees, antivirus vendors, customers, researchers and Google. Readers seeking a neutral institutional history should pair this narrative with independent reporting, including El País’s contemporary account.
More history than manual
The book is not a procedure guide for malware analysis. It does not substitute for current VirusTotal documentation, API references or specialist training. Its technical explanations serve the story, so readers looking for architecture, sample-handling policy, privacy details, false-positive methodology or operational instructions may find less than they want.
Translation caveat
Some English-language reader feedback describes phrases as slightly unnatural, a plausible consequence of translation from Spanish. This is anecdotal rather than a systematic editorial assessment, and it should not obscure the book’s accessibility or narrative strengths.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.VirusTotal’s present-day practical context
The book’s legacy questions are easier to understand when separated from current product rules. As of August 18, 2026, VirusTotal’s documentation says registered users can use the public API for free, subject to a limit of 500 requests per day and four requests per minute. The public API may not be used in commercial products, services or business workflows that do not contribute new files. Professional or premium access is available through VirusTotal’s advanced services, but the cited documentation does not publish a price and directs prospective users to contact the company. See the official public-versus-premium API documentation.

Those rules do not turn the book into a product guide, but they sharpen its institutional question: how does a platform built around broad information sharing balance public access, commercial services, privacy and responsible handling of submitted material? The memoir’s limited post-acquisition coverage means it does not provide a complete answer.
Who should read it?
| Reader | Recommendation |
|---|---|
| Cybersecurity professional | Yes—especially for origin history, personalities and industry context. |
| Threat-intelligence practitioner | Yes, but treat it as context, not a technical reference. |
| Startup founder | Yes—for unconventional entrepreneurship, timing and acquisition lessons. |
| General technology reader | Yes, if behind-the-scenes technology stories appeal to you. |
| Malware analyst seeking procedures | No—the book is not a hands-on analysis manual. |
| Reader seeking Google corporate history | Only with reservations; the post-acquisition period is underdeveloped. |
Buying and edition checks
- Look for the full English subtitle and ISBN 9788409683666 or 8409683660.
- Do not confuse the English translation with Infectado: Del Spectrum a Google, el camino de un emprendedor accidental.
- The author has referenced an Amazon listing at amazon.com/dp/8409683660; availability and import costs can vary by country.
- An AbeBooks listing showed a used U.S. copy at US$26.69 plus shipping when crawled, but that marketplace price is neither a stable retail price nor a guarantee of stock. Check the listing at AbeBooks.
Final verdict
Infected succeeds as a founder’s account of how curiosity, malware research and a practical side project became one of cybersecurity’s most recognizable platforms. Its best material explains VirusTotal’s birth, the cooperation and resistance surrounding it, and the human stakes of selling to Google. It is less successful as a complete institutional history—particularly after the 2012 acquisition—and should not be mistaken for a technical manual or an official Google history.
