That’s an increase of over 70,000 per day. By 2014, there were 37 million virus hashes just a year later there were 64 million. By 1999, that number was close to 100,000.ĭespite slow beginnings, the number of viruses started growing exponentially. AV-Test, one of the popular maintainers of such databases, reported in 1994 to have just over 28,000 viruses on file. The hash approach worked particularly well when there were only a limited number of viruses.
This makes it possible to store many such hashes in a downloadable database. Hashes are always only a few characters long, no matter how large the file is, and they can be calculated relatively easily. Every digital file can be identified by what is called a hash, and each hash uniquely represents a known virus.
How antivirus programs workĪntivirus programs typically work by maintaining a list of all known viruses. And in 1991, Norton Antivirus was founded in the United States. Then, later the same year, Pavel Baudiš and Eduard Kučera created Avast in the Czech Republic. In 1988, Avira was founded in Germany by Tjark Auerbach. John McAfee founded the eponymous company that made him famous in 1987, and more antivirus companies emerged shortly after. The Morris Worm was a wake-up call for many, and it helped kick-start the emerging antivirus industry. The irony is that we know the scale of the attack because the virus was created to calculate the size of the internet. It’s estimated the worm caused between 100,000 USD and 10 million USD in damages. Though the Morris Worm was not built to wreak damage, a few programming errors allowed it to disable over 6,000 computers in just a few hours-around 10% of the internet at the time. The writer, Robert Tappan Morris, did not intend harm either, but that didn’t protect him from being the first person convicted under the new 1986 Computer Fraud and Abuse Act. Just two years later, in November 1988, the first virus spread across the internet. The Morris Worm was the first computer virus Indeed, they even included their names, address, and phone numbers in the software. The writers released the virus with no malicious intent. Things escalated quickly and Brain spread to many more machines than anticipated. Brain was a virus written by two Pakistani brothers in 1986, intended to track pirated copies of their heart-monitoring program. It was another 15 years of mostly harmless and experimental viruses before Brain was born. The second computer virus in existence, dubbed Reaper, was created with the sole purpose of destroying Creeper. While computer science had theorized self-replicating computer programs since the late 1940s, it was only in 1971 that the first virus, called Creeper, was created.Ĭreeper did not do any particular harm it could only display a message. To understand why, read below about the history of malware, what antivirus software does, and how you can protect your computer. Tl dr: No, antivirus software no longer reliably protects against malware threats.
