This day in history: The first computer virus hits the world

On January 19, 1986, the computer virus Brain emerged, recognized as the first major global threat in cybersecurity. Created by Basit and Amjad Farooq Alvi in Lahore, Pakistan, it targeted IBM PC-compatible machines running MS-DOS and spread via floppy disks. Brain was initially intended to protect the brothers' medical software from piracy by tracking unauthorized copies. It embedded itself in the boot sector of infected computers and displayed a message with the creators' contact information. Despite its benign intent, Brain spread internationally, highlighting the potential for software to replicate and traverse borders autonomously. This event raised awareness about computer viruses and initiated discussions on antivirus solutions and the ethical responsibilities of programmers. Brain exposed vulnerabilities in early personal computers and prompted the integration of cybersecurity considerations into software design.

Bernardo Quintero Uncovers Creator of Virus Málaga and Cybersecurity Legacy | Ukraine news

Bernardo Quintero sought to find the programmer behind the Virus Málaga, which had a significant impact on his life and career in cybersecurity. The virus, initially a piece of malware, sparked Quintero's interest in the field and led to the creation of VirusTotal, which was acquired by Google in 2012. This acquisition helped elevate Málaga as a tech hub in Europe. Quintero revisited the virus code and discovered a clue linking it to a programmer named Enrique, who was affectionately known as Kiki. He learned from Antonio Astorga, a source who passed away, that the virus contained a hidden message against the Basque terrorist group ETA. Astorga's legacy continues through his son, Serhiy, who has aspirations in cybersecurity and quantum computing.

Identity Theft Protection vs. Antivirus: Where to Spend First

Antivirus software and identity protection services serve different purposes in digital security. Antivirus software protects devices from malware, offering real-time protection and scans, but it does not monitor personal information or financial accounts outside the device. In contrast, identity theft protection services monitor personal information like Social Security numbers and financial accounts, alerting users to potential identity theft and providing recovery assistance. The choice between these services depends on individual circumstances, with antivirus software recommended for device security and identity monitoring prioritized for those concerned about identity theft. Free strategies to enhance security include using free antivirus software, strong passwords, two-factor authentication, and regular updates to devices and software.

12 ways to find viruses on your PC for free (and how to remove them)

In cybersecurity, modern viruses operate subtly, making them hard to detect while stealing data. Signs of infection include unfamiliar programs, missing files, erratic browser behavior, frequent error messages, and disabled security settings. If infected, disconnect from the internet, boot into Safe Mode, and run a full scan with Windows Security or trusted antivirus software. To protect your PC, delete temporary files, reset browser settings, uninstall suspicious apps, scan external drives, install updates, change passwords, and avoid suspicious links. For suspicious files, use VirusTotal to check for malware. If problems persist, a complete reinstallation of Windows 11 may be necessary after backing up important files.
