We have come a long way from glitching Windows screens to adware and just plain annoyance viruses. Windows 10 today doesn’t feel as unsafe as the operating system in its earlier days. Infections are mainly managed by Microsoft’s built-in Windows Defender, and tech-savvy users may manually spot phishing attempts and viruses with appropriate digital hygiene. Do you need antivirus software in 2021, given how Windows protects you from digital dangers automatically?
While contemporary operating systems have made it possible to manage viruses to some level, harmful apps have recently plagued digital users. WannaCry was the infamous ransomware crypto worm that encrypted around 200,000 computers across 150 countries. Mydoom, a worm, is considered one of the fastest spreading email worms with computers getting affected even today since its inception in 2004. The numerous viruses that attack your computer have evolved along with security. Viruses used to be primarily meant to irritate or show unwanted material; however, the contemporary digital landscape has given rise to more complicated viruses with a specific goal. Malware such as Stuxnet has been used to destroy and damage nuclear power facilities, as well as participate in cyber warfare.
Antivirus software like Windows Defender is good in detecting known threats, blocking unwanted applications and network attacks but newer and newer viruses are developed which might not be identified in virus databases. These new varieties may easily evade antivirus scans, and by the time they are discovered, they may have already wrecked havoc on your system. Social engineering infections, even more than direct network attacks, are one of the most prevalent methods for computers to get infected. If you don’t know what to look for, a phishing site that looks just like Facebook’s login screen might be a scam.
While established attacks are easier to defend against, internet users should be more concerned about emerging threats that exploit undiscovered weaknesses within a system. These days, your computer’s ability to be exploited as a botnet and get access to your personal data can be devastating. While third-party antivirus software provides all of the features of Windows Defender, it also includes additional useful tools to keep you secure online.
Antivirus software like Kaspersky Internet Security, ESET Internet Security, Avast Antivirus, McAfee and BitDefender are all available in Nepal through eSewa or Khalti. There are free versions of all of this antivirus software, but if you want to pay for the service, there are local dealers for it. However, for a free service, we recommend sticking with Windows Defender because the integrated program integrates seamlessly with Windows and uses very few resources. Free versions of any of these third-party services might provide a few extra functions, but Windows Defender should suffice for the most part.
The true value of these services can only be found in their paid editions. Almost all third-party antivirus software includes threat detection based on machine learning and artificial intelligence. Password Managers are also available from some companies, such as Kaspersky and McAfee, to help you complex and secure your passwords. Ransomware remediation, for example, helps you secure your files even after your machine has been attacked with ransomware. All of the aforementioned antivirus software has excellent threat detection, which is aided by the fact that threat detections are now shared across all antivirus products. However, several companies now provide VPN services and software for extra privacy protection.
Extra protection is fine, but it won’t help much if it consumes all of your system’s resources. Antivirus software has a history of being resource hogs, causing your computer to totally freeze when an active scan is going. With Windows Defender’s near-invisibility, this doesn’t appear to be an issue, but what about third-party security solutions? Any new antivirus will eat up part of your system resources, but it’s not as severe as it used to be. This is also due to the fact that hardware has improved over the last decade, and what used to be heavy programs now run smoothly on just one core of your CPU, leaving you with plenty of parallel processors to deal with. While idle, Kaspersky, ESET, and McAfee all boost system resources by a few percent, but these are minor increases that don’t influence system processes until they’re conducting active scans. Norton was the most resource-intensive, although system performance was only marginally affected.
Would I advocate putting an antivirus on your contemporary 2021 PC, given everything? Absolutely. Any of these security solutions’ additional protection will not only safeguard your computer against viruses but will also act in response to harmful software. Password Managers and VPNs are must-haves in today’s world, and even if you don’t wind up paying for any of these antiviruses, free Password Managers (BitWarden) should be an important application for each internet user to keep their online accounts safe. Investing in one of these premium antivirus programs will undoubtedly improve the security of your data, but it will come at a cost. For those seeking a free solution, we also propose the default Windows Defender. Viruses aren’t what they used to be, and they’re being exploited for more malicious purposes than ever before, which is why considering cybersecurity is essential if you want to stay secure in the digital world.
