The First Computer Virus in the Philippines

ILOVEYOU virus, also known as Love Bug or Love Letter, was an exceptionally malicious computer worm which infected millions of systems worldwide and caused $10 billion worth of damages before antivirus and cybersecurity software could stop its spread.

What is The First Computer Virus in the Philippines. Onel de Guzman of AMA Computer College Manila created the worm as part of his undergraduate thesis project for his undergraduate thesis defense, sparking debate about cybersecurity vulnerabilities and legislation designed to combat cybercrime. It quickly spread through Manila-area networks before being shut down by authorities.


The ILOVEYOU virus, also known as the Love Bug, was one of the most devastating computer viruses ever to exist. It caused millions of computers to crash and severe financial damages were sustained by businesses and government institutions alike. Spread via email with its clever manipulation techniques which capitalized on people’s natural curiosity by tricking them into opening an attachment from which it then overwrote essential system files before sending copies itself out to all contacts in each victim’s address book – the estimated damage costs from this virus alone total $15 billion worldwide.

Onel de Guzman was responsible for creating this malware worm during his final thesis at AMA Computer College in Manila as an undergraduate. His original goal for creating it was to gain Windows passwords and extract Internet accounts stored on victim machines – at that time there were no laws against creating malware so he was never prosecuted for his work.


The ILOVEYOU worm was one of the earliest widespread computer viruses and an early wake-up call for governments, businesses, and individuals alike to take cybersecurity more seriously. The virus infected millions of computers worldwide and caused billions in losses; additionally it exposed vulnerabilities that persist today despite decades-worth of advances in computer security technology.

The virus spread through email by exploiting people’s natural curiosity to open attachments. Once infiltrated into a computer system, once it became infected it would send copies of itself out via all contacts in its address book and overwrite essential system files, leading to massive email outages and overwriting important system files.

Onel de Guzman was responsible for creating this virus as part of his undergraduate thesis; no legal charges were ever laid as there were no laws in place at that time to punish cybercrimes. Now employed at a modest phone repair shop in Manila, de Guzman remains anonymously free.

ILOVEYOU malware

The ILOVEYOU virus, also known as Love Bug and Love Letter, is one of the world’s most notorious computer viruses. It caused havoc across computers worldwide by infecting and disrupting business, corporate and government systems; its rapid spread shook global awareness to cybersecurity risks; its fight back made headlines around the globe and awakened complacent audiences to cybersecurity risks.

Worms differ from traditional viruses in that they do not need host-file activation to start infecting systems; rather they spread through internet connections and infect all exposed systems.

Reonel Ramones and Onel de Guzman, two Filipino computer programmers, developed the ILOVEYOU worm which was released in May 2000 through email attachments and became the largest malware outbreak ever. De Guzman claimed he created it to steal passwords without paying, which enabled access to the Internet for free without paying. No charges were ever brought because at that time no laws against hacking existed in the Philippines.

ILOVEYOU exploit

The ILOVEYOU virus was an infamous computer worm that infected millions of computers worldwide and exploited vulnerabilities in Microsoft Windows to spread rapidly through email attachments, leading to major financial damages as well as global panic. This outbreak underscores the necessity of strengthening cybersecurity features to combat any future cyberthreats.

Onel de Guzman of Philippines College created ILOVEYOU as part of his undergraduate thesis at AMA Computer College; however, he didn’t anticipate its viral nature and widespread harm caused by it.

This virus spread through email inboxes by searching out victims, then sending copies of itself directly to those victims’ contacts. Although its author was arrested in the Philippines, all charges against her were later dropped after authorities realized there were no laws against creating malware at that time in her homeland.

ILOVEYOU was the first major computer virus linked to the Philippines, showing how cyberattacks could come from anywhere and create serious difficulties for businesses.
