No, malware threats are no longer reliably prevented by antivirus software. Read on for information about the origins of malware, the functions of antivirus software, and ways to safeguard your computer to understand why.
Even though computer scientists have postulated self-replicating computer programs since the late 1940s, the first virus, Creeper, wasn't generated until 1971. Creeper could just show a message; it could not do any specific harm. Reaper, the second computer virus known to exist, was designed to eliminate Creeper.
Two brothers from Pakistan created the Brain virus in 1986 to locate unauthorized copies of their heart-monitoring software. Things rapidly got out of hand, and Brain expanded to many more devices than anybody had predicted. The authors didn't mean any harm when they distributed the virus. The program had their phone numbers, addresses, and identities.
The First Computer Virus Was the Morris Worm
The first virus hit the internet in November 1988, only two years later. Despite not intending to harm, Robert Tappan Morris, the writer, was found guilty as the first person under the newly enacted Computer Fraud and Abuse Act of 1986.
Although the Morris Worm was not intended to cause harm, a few programming mistakes allowed it to take down over 6,000 machines in a matter of hours, or around 10% of the internet at the time. The worm is thought to have cost between $100,000 and $10 million in damages. The irony is that because the virus was designed to determine the size of the internet, we are aware of the extent of the attack.
The Morris Worm awakened many people and catalyzed the nascent antivirus sector. Following the founding of his now-famous firm, John McAfee, other antivirus companies quickly followed suit. Tjark Auerbach started Avira in Germany in 1988. Later that year, Pavel Baudiš and Eduard Kučera founded Avast in the Czech Republic. Additionally, Norton Antivirus was established in the US in 1991.
How Antivirus Software Functions
Generally, antivirus software functions by keeping track of all known infections. A hash, which uniquely identifies a known pathogen, may be used to identify any digital file.
No matter how big the file is, hashes are always only a few letters long and are rather simple to calculate. This enables the storing of several hashes in a portable database.
Despite their modest beginnings, the number of viruses started to increase dramatically. There were 37 million viral hashes in 2014; a year later, that number had risen to 64 million, a daily rise of more than 70,000.
Most viruses now act like biological organisms and change somewhat with each replication, a trait known as polymorphism. The virus will still perform its primary job, but its hash will no longer be able to identify it uniquely.
‘Allow All’ Antivirus Became ‘Deny All’ Browsers
Today's browsers and operating systems are designed to withstand polymorphic viruses. Contemporary apps and systems are designed to refuse access to everything unless the user explicitly grants it, in contrast to the outdated security approach, which frequently developed around the idea of "allow all, then add exceptions."
Even antivirus vocabularies with millions of words are likely to overlook certain threats due to the sheer volume of them (viruses and hacking attempts). Viruses are evolving so fast that no two versions of the virus are the same.
As a result, antivirus seldom functions in its current form. In addition to being pricey, it might cause your computer to lag, conflict with other programs, and mislead you into feeling secure. Instead, you may perform the following:
The Best Ways to Keep Your System Safe
1. Maintain an Updated System
Any threat to your system will search for little vulnerabilities and cracks to take advantage of. Although faults are not uncommon, they are often fixed quickly enough to prevent significant security flaws from developing.
To protect yourself against malware, keeping your software and apps updated on your computer, phone, and other devices is critical. Although it might be tedious sometimes, keeping yourself safe is the most important thing.

2. Make Frequent Backups of Your Files
Even if you keep your system updated, you may become infected with a virus. New risks always emerge that need to be examined and identified; some may even be directed directly at you. You can't expect an antivirus program to protect you from every attack.
All your data should be regularly backed up and stored on a different drive; preferably, the drive should be unplugged when the backup is completed. This will enable you to swiftly reinstall your operating system from scratch, which is sometimes the only surefire method to remove a virus.
Does a VPN Shield Me from Malware?
A VPN does not provide virus protection by itself; however, it does prevent harmful code from being injected into your browser sessions by your local ISP or Wi-Fi provider. A VPN keeps your IP address hidden and encrypts your data so it remains safe from prying eyes.
You should be cautious while opening downloads and email attachments, even when connected to a VPN. Files in questionable formats, like.exe .jar or.js, should never be opened. Only files from reliable sources should be opened. If you have concerns about an attachment from a reliable source, consider contacting them via a different route to be sure the communication is genuine.
Sure, You Can Still Use Antivirus Software
As long as you have one antivirus application installed (two of them will probably conflict with one another), there is no real danger in using one. However, if your computer becomes sluggish or your apps stop functioning properly after installing antivirus software, you might want to look into changing service providers.
Additionally, antivirus software can help you find dangers concealed in other files or backups. You definitely don't want them on your system, even if they cannot infect your upgraded PC.
