What is the Most Used Anti-Virus for Computers?
The most used anti-virus product for computers is most likely Symantec (which offers Norton 360 among many other cybersecurity products). Symantec is popular because the basic plan has very high detection and removal scores.
With that said, according to Statista, even though Symantec Corporation has the most market share (13.16 percent), other antivirus companies are not far behind including AVAST (12.69 percent), and ESET (11.45 percent), and Webroot Software Inc (8.79 percent) among others. On Windows, Norton 360 offers the most all-around antivirus product, which could be a significant factor explaining the product’s popularity.
Note:It is important to consider that market share percentages may change according to the type of customer being referred to. For example, McAfee is very close to the top when talking about business antivirus solutions using Windows as the operating system.
Which Anti-Virus Software is the Best for All Computers?
The best antivirus software for all computers varies on the requirements of the user and the features a particular individual/publication/review-site considers important. The general consensus seems to be between Norton 360, Mcafee, and Bitdefender. Bitdefender may top this list as it not only gets great praise from various publications and individuals but also independent antivirus testing labs.
How Does Anti-Virus Protection Work?
Antivirus Protection, for the end-user, works when antivirus vendors make users install an antivirus product on the device that needs protection. Once the app is installed, simply launching the antivirus app makes antivirus protection work. Modern antivirus products try very hard to stay out of the way of the user with security-related tasks (such as definition updates, software updates, detection and removal of malware) getting completed in the background.
From the point of view of the vendors, antivirus products help users gain protection against malicious threats with tools such as scanners, firewalls and virus definitions, amongst many others. A typical antivirus program will protect users by first scanning the user’s device for signs of malicious content. If some malware is found, the antivirus program will move to remove the said file/object from the device. Depending on the antivirus vendor the user signs up for, the antivirus program may or may not put up a notification.
Note:Readers should also understand that antivirus programs not only work against viruses but all sorts of cyber threats such as worms, spyware and ransomware. In other words, there are many uses of antivirus software for computers.
Modern antivirus programs make use of five main techniques to handle malware. These techniques include behavior monitoring, machine learning (or AI), sandbox detection, heuristic analysis and signature-based analytics. Signature-based analytics represent the most common and perhaps the oldest technique to catch malware. Antivirus programs also have a database (which is regularly updated) of malware once the malware has been previously discovered. Antivirus programs, upon facing a threat, simply compare the new threat’s fingerprint with the fingerprints available within the database. Upon a match, the antivirus program will at least push a notification if not remove or quarantine the threat.
Behavior monitoring is a new technique where antivirus programs work by keeping an eye on a given device’s behavior. If the user has connected any devices to the main device, the antivirus programs monitor the connected devices as well. Whenever a behavior is found to be suspicious, the antivirus program can either stop the malicious device and/or reverse any harmful changes.
Most of the antivirus programs mentioned in the above list also make use of machine learning techniques to adapt to any new techniques hackers may come up with while trying to infect a device. Once a new threat is identified and learned about, the information is passed to a database. The more information the program sends to the database, the better the antivirus program becomes at stopping unknown cyber threats from damaging the user’s device.
Heuristic analysis is the technique of distinguishing malware threats acting as legitimate files/traffic/folders/downloads with complex trial and error methods. If an unknown threat is able to bypass signature-based detection, antivirus programs can use heuristic analysis to catch the virus and stop any harm.
Finally, some antivirus programs work via sandbox detection. Sandbox Detection allows antivirus programs to open a suspicious file in a secure environment. If the code is harmful then the antivirus program would either remove the malicious file or transfer the file to quarantine.
Who is authorized to install anti-virus software?
Depending on the operating system of the device that needs protection, the admin or root user has the authority to install anti-virus software. Recent Windows versions allow non-admin users to install antivirus software as well if given permission by the administrator. In Linux and macOS, the root user can install antivirus programs. Even then, the user has to provide the root password to install antivirus applications.
Generally, the Android and iOS devices only have one user who is able to install antivirus applications (in some cases after giving the proper permissions to appropriate programs via separate dialog boxes). In this case, anyone who knows how to install antivirus can do so.
How Should Anti-Virus Software Be Used?
Follow the steps given below to correctly use antivirus software.
- First ensure the antivirus software package comes from the official website. There are many websites online that distribute malicious versions of legitimate software applications. Then download the software.
- Once the antivirus software is downloaded, double click on the downloaded file (in the case of Windows and macOS), grant proper permissions and wait for the installation process to finish. On the mobile platform (Android and iOS), the download and installation step is the same as the Google Play Store and the App Store perform all necessary steps automatically. Mobile users only need to select the desired antivirus product from the appropriate app platform.
- After the installation is complete, run the app and go through a few screens to set up the antivirus applications.
- Once the program has been launched, there is nothing significant to do manually. As previously mentioned, modern antivirus programs usually stay away from the user’s screen and do all the protection work behind the scenes. From time to time, however, it is worth checking if the antivirus application is enabled and is receiving regular updates (along with the remaining subscription period).
- Finally, if the antivirus application doesn’t perform scans automatically, the recommended way is to individually scan suspicious files downloaded either via email service or a device like a USB. This step is not necessary on many current antivirus applications.
- How to Use Anti-Virus Software for the First Time?
Generally, the first time a user installs an antivirus product, the antivirus service may ask for not only a username/password but also an activation code. The activation code will be available either in the confirmation email or on the backside of the antivirus product’s physical package. Once the antivirus program has been activated, run a complete scan. Some elite antivirus products offer the Quick Scan option, on launch, as well to make sure everything is fine on the device.
- How Often Should Computer Anti-Virus Be Used?
Since the vast majority of computing devices today (including desktop computers, laptops, mobile devices and some IoT) are connected to the internet all the time, users must use antivirus programs at all times.
Elite antivirus programs usually allow users to change settings and have the antivirus program launch at Windows start-up. Moreover, antivirus programs are now able to warn the user if the program is closed either by the user accidentally or by a malicious program.
Is Antivirus Software Really Necessary?
For most users, yes, antivirus software really is necessary. While there are arguments that modern users don’t need antivirus software, extra security never harmed any online device.
Since the majority of computing today happens over the internet, antivirus programs have become less important. Moreover, web browsers have also become very secure to use and carry out daily online tasks which has further decreased the need for antivirus applications.
Then there is the fact that most applications and operating systems (desktop and mobile) can update themselves without user intervention. Add to that built-in antivirus protection systems in operating systems, apps and web browsers, and users shouldn’t find it difficult to understand why antivirus software is not as important as before.
However, users who have transferred the majority of offline tasks to the online world still need that extra bit of protection that antivirus products are very adept at providing.
Is Computer Anti-Virus Software Effective?
Yes, computer anti-virus software is very effective. Of course, hackers are always coming up with newer ways of disrupting communication networks and the devices that are on those networks. Antivirus products simply cannot guard against all totally new threats from the minute hackers unleash into the wider world of the internet. However, antivirus products can at least limit the damage caused if a given device gets infected.
Yes, old antivirus products that only relied on signature-based techniques are not effective anymore. But elite antivirus products that can take advantage of the latest techniques such as machine learning and behavior analytics can manage unknown threats reliably. As a result, generally, antivirus products are effective.
