Strong Antiviruses for 2020


Antivirus: Definition,Types, and Examples

Definition of Antivirus Antivirus software is a type of utility used to scan and remove viruses from your computer or smartphone. While many types of antivirus (anti-virus) programs available, the main purpose of creating antivirus is to protect computers and smartphones from viruses and remove any detected viruses. Most of antivirus programs have both manual and automatic scanning capabilities. Automatic scanning can check files anywhere, whether files that are downloaded from the Internet, or disks that are inserted into a computer or smartphone, even files that are created by the third party software. Automatic scanning can also scan the entire hard drive regularly.

The manual scanning option allows you to scan files one by one or the entire system whenever you want. Because of the growing technology, new viruses are constantly being made by hackers. Therefore an antivirus program must store an updated database of virus types. This database collected from list of “virus definitions” that are referenced by antivirus software when scanning files. Because new viruses are often distributed, it is important to always update the virus database from your antivirus software. But don’t worry, most antivirus programs automatically update the virus database every months even weeks. Basically, antivirus software is primarily designed to protect computers and smartphones against viruses. But now there are many antivirus programs that are able to protect against other types of malware, such as rootkits, adware, and spyware as well.

Antivirus software can also be reinforced with firewall features, which help prevent hackers from accessing your computer and smartphone. Utilities that have antivirus and firewall features are usually branded “Internet Security” software. In addition to antivirus, you should also understand about computer viruses. Because if you have understood the definitions, types, and examples of computer viruses, you can determine which antivirus is appropriate to ward off existing computer viruses. Most antivirus programs are available for Windows, Unix platforms, and Macintosh. But most antivirus software is made for Windows systems. This is because most hackers target viruses to computers with Windows systems. Therefore virus protection like antivirus is very important for Windows users. If you are a Windows user, you should have at least one antivirus program installed on your computer, or your smartphone if it also use Windows system. Here are a few examples of common antivirus programs, include Norton Antivirus, Kaspersky Anti-Virus, AVG Antivirus, and many more.

Alternatively referred to as antivirus software, AVS, antivir, or AV. An antivirus program is a software utility designed to protect your computer or network against computer viruses If a virus is detected, the computer displays a warning asking if the infection should be quarantined, removed, ignored, or moved to the vault.

What are the different types of antivirus protection?

Several types of antivirus programs have evolved over the years. When setting up your umbrella of protection, it’s important to understand the more common antivirus programs available.

Malware signature antivirus

Malware, or malicious software, installs viruses and spyware on your computer or device without your knowledge. Malware can steal your login information, use your computer to send spam, crash your computer system, and essentially give cybercriminals access to your devices and the information stored on them, and even the ability to monitor and control your online activity.

Malware signature antivirus software detects malware signatures, which are digital fingerprints of malicious software. Antivirus protection can scan for specific malicious codes, identify specific viruses, and disable these programs.

While malware signature antivirus protection is key for detecting and eradicating known viruses, one limitation is its inability to address new viruses. The antivirus product simply doesn’t contain these new virus signatures.

System monitoring antivirus

This is where system monitoring antivirus software comes into play. This antivirus protection can monitor software and computer systems for behavior that is suspect or atypical of the user.

For instance, alerts are created when a user connects to unfamiliar sites or attempts to access a large number of files, or when there’s a significant increase in data usage.

Machine learning antivirus

Another form of protection can be machine learning techniques, which monitor “normal” computer or network behaviors. The machine learning antivirus software is able to limit activities by programs or computers if they look suspicious.

More specifically, machine learning detection implements algorithms to facilitate malware detection that is broader in scope. This type of antivirus protection is beneficial because it works in tandem with other antivirus applications to provide multiple layers of protection.

One example of machine learning is the design of Microsoft’s latest antivirus software, which can gather data from more than 400 million computers running on Windows 10 to discover new malware. (Note: To be clear, this is diagnostic data that a consumer can opt out of reporting.) This, in turn, takes us back to the importance of signatures, as this intelligence will allow for the development of new signatures for the latest malware discovered. This automation is key in its ability to stay on top of the latest viruses.

What does antivirus software help protect us from?

The beauty of malware for hackers is its ability to gain access to or damage a computer without our knowledge. It’s important to be aware of the many different types of malicious codes, or “malware,” against which antivirus software is designed to protect:

  • Spyware: stealing sensitive information
  • Ransomware: extorting money
  • Viruses
  • Worms: spreading copies between computers 
  • Trojans: promising one thing but delivering another 
  • Adware: advertising
  • Spam: spreading unwanted email

Isn’t Windows Defender enough?

Starting with Windows 8, Windows has built-in antivirus protection known as Windows Defender that is enabled by default. But is it enough? The answer is “maybe” in that its efficacy isn’t certain due to its reliance on several moving parts.

For instance, Windows Defender is a good defense against traditional viruses. But it may not detect threats beyond regular viruses, and may not protect your devices against more sophisticated infiltrations such as ransomware. So its effectiveness also depends on how careful you are as an individual. Are you going to click on that link or email attachment from an unknown sender or website? In order to be safe, you likely need an added layer of protection.

Do I need antivirus protection for Mac?

While Macs and other Apple devices may not be as frequently targeted as Windows computers, it’s still a good idea to get additional antivirus protection to be ready for what may come in the future. At the moment, if you’re careful about what you open, don’t click on unknown links or attachments, and are careful in your online activity, you may be safe. But is it an unknown risk you’re willing to take? “Safe for now” may transition to “no longer safe.”

Free antivirus software: Does it work?

Another common question is whether free antivirus software protects us. But is anything ever really free? “Free” antivirus inevitably supports and makes money with advertising and tracking, and by installing junkware.

Free downloads also can hide malware. If you go this route, only download software from sites that you absolutely trust. You also must ensure that your security setting is set high enough to detect malicious codes.

Another thing to keep in mind when considering whether to rely on free antivirus protection? Identity theft protection, mobile security, and data security support options. These important security features often are lacking with free software.

Considering all of the risks mentioned above, third-party antivirus protection can be critical. It can mean the theoretical difference between browsing online safely — with your financial and personally identifiable information (PII) safe inside your lockbox at home, and going shopping with your personal and financial information available for the taking.

Norton 360 features top-of-the-line defenses against these cyber threats, safeguards your PII and online transactions, and ensures emails and links come from trusted sources. Don’t leave your cybersecurity up to chance; sign up for the latest in antivirus protection.
