Pros And Cons Of Antivirus Software

Keeping your computer free from viruses, malware, and other types of attacks is easier than ever thanks to antivirus software. However, there are some downsides to using antivirus software that you should be aware of before installing it. This guide will help you decide if antivirus software is right for you.

In this guide, we review the Pros And Cons Of Antivirus Software, why do we need antivirus, how to use antivirus software, and disadvantages of anti malware software.

Pros And Cons Of Antivirus Software

Antivirus software is a great way to keep your computer free from viruses, malware, and other types of attacks that can cause you harm. However, there are some downsides to using antivirus software. This guide will help you decide if antivirus software is right for you.

Antivirus software is notorious for slowing your computer down.

Antivirus software is notorious for slowing down your computer. It’s a trade-off between security and speed. If you want to make your computer faster, you should uninstall your antivirus software so that it doesn’t bog down your system when doing everyday tasks such as browsing the internet or watching videos.

Antivirus software can detect and prevent all types of malware.

Antivirus software is intended to detect and prevent all types of malware, but it’s not the same as anti-malware software.

Antivirus software can detect and prevent malware, but it cannot remove it. If your computer has become infected with a virus or other type of malicious software (malware), you’ll need to use an anti-virus program that comes equipped with a removal tool. This tool will allow you to remove the offending files from your system so that they can’t cause further damage or infection later on down the road.

If you’re using Windows 10 and have antivirus and antimalware programs installed on your computer at home, keep in mind that these two types of security products serve different purposes for users. Antivirus programs scan computers for existing infections while antimalware programs try to prevent future ones from occurring by detecting signs that some sort of attack may be taking place (like when strange files are added).

Antivirus software is effective at protecting you from ransomware.

If you’re concerned about the safety of your computer and the files on it, antivirus software is an important investment. Ransomware is a type of malware that encrypts your files and demands payment in order to decrypt them. The most common way ransomware gets onto a computer is through email attachments or links in emails. Antivirus software can prevent this from happening by detecting any malicious code before it enters your system.

There are many different types of antivirus programs available, so make sure to choose one that’s right for you—and always keep it updated!

You need antivirus software to protect against active attacks.

If you’re worried about malicious attacks, it’s a good idea to have antivirus software installed on your computer.

Antivirus software can prevent active attacks—when someone is actively targeting you and trying to get into your computer. For example, some of the ways that viruses spread are through email attachments, websites that advertise malware (malicious software) or social media posts with links. These kinds of digital dangers are what antivirus programs were designed to protect against

Antivirus software cannot prevent malware attacks while you are offline.

While antivirus software is helpful when you are online, it cannot prevent malware attacks while you are offline. If you’re not connected to the internet, there’s no way for your antivirus software to know that a malicious program has been installed on your computer.

Because of this, it’s important to be cautious about what types of files and programs—both on your computer and in emails from unknown senders—you choose to open or install. In general, the best way to protect yourself against malware is by using common sense: avoid clicking on suspicious links or attachments; don’t install software that hasn’t been fully vetted (for example, apps from unknown publishers); keep up-to-date with patches from Windows and other OS providers; enable two-factor authentication wherever available; turn off file sharing if not needed; don’t visit shady websites or download pirated content; and so forth.

Antivirus software could be a target for hackers to gain access to your system.

As an antivirus software, it can be a target for hackers. Antivirus software is a gateway to your computer so the software can be exploited to gain access to your system. A common way that this happens is by tricking the antivirus into thinking it is being attacked by malware and then having it perform actions that give the hacker access too. Because of this risk, some people choose not to use antivirus software at all because they believe it’s better not to have one than have one that could be hacked.

Antivirus software can help keep your computer safe, but it can also make it run slower.

People who use antivirus software may find that it slows down their computer’s performance. This is especially true if you have a lot of files on your computer, such as photos and videos.

Antivirus software can help protect against active attacks, but it cannot protect you while you are offline.

The best way to protect yourself against ransomware is by backing up files regularly so that viruses don’t encrypt all of your files at once.

why do we need antivirus

Viruses sound scary, especially in light of the COVID-19 pandemic. Of course, viruses don’t just apply to humans; they also apply to any internet-connected device, computers, phones, and tablets in particular. But as some operating systems have built-in antivirus protection, is getting a third-party antivirus software necessary?

Do You Still Need Antivirus?

Overall, you probably still need antivirus software, but some devices need it more than others. The only operating system that you absolutely do not need to install antivirus software on is iPhones. However, Windows, macOS, and Androids still need antivirus software.

Tested Antivirus Software for your Computer

We spend a lot of time making sure antivirus software will help protect your devices. We make sure risks against ransomware, spyware, malware, and other online threats are checked so you don’t have to. Below is a list of the highest-scored antivirus software.

Why You Still Need Antivirus Software

Every day, new malware and other online threats emerge. In fact, the AV-Test Institute registers over 350,000 new pieces of malware and potentially unwanted applications (PUA) every day.1 Yes, you read that right: every single day. In general, malware is more of a problem than PUAs, making up 90 percent of all total threats in 2020 vs. the 12 percent from PUAs.

That being said, some operating systems are much more susceptible to viruses than others, with Windows coming in first. 87 percent of ransomware targeted Windows computers as of January 25, 2021, according to managed service providers (MSPs).2

Similarly, data from AV-Test showed that Windows devices had the most new malware and new PUA in all of 2020 and January of 2021, followed by Androids and then Macs. In sum, unless you have an iOS device like an iPhone or iPad, antivirus software is a necessity.

How Antivirus Protects Your Devices

In a nutshell, antivirus software will scan your devices for viruses, malware, and other cyber threats. If it detects anything malicious, it will quarantine and remove the file. Let’s get into a bit more detail.

Main Features

Here are the basics that every antivirus includes in its software:

Extra Features

A lot of antivirus software is bundled with other digital security software, such as:

The Argument Against Antivirus

Of course, those that say that antivirus software isn’t necessary aren’t completely wrong. It’s definitely not needed for iOS devices, nor does it exist for iOS devices in the first place.

FYI: While some antivirus companies may trick you into thinking you are downloading antivirus for iOS devices, it is usually some form of mobile security that doesn’t include virus protection. Be sure to read the fine print!

There’s also the argument that antivirus software is expensive, which we must agree with, unfortunately. On average, antivirus costs around $40 a year, and term lengths aren’t usually any shorter. And while some free antivirus software exists, it usually limits things like the number of devices you can connect or the amount of time you can use it. Finally, some devices like Windows and Macs have built-in antivirus software, so many feel that additional third-party software is unnecessary. Well, we did some investigating, which brings us to our next topic…

Built-In vs. Third Party Antivirus Software

If devices already come with virus protection, antivirus software is useless, right? Wrong. Let’s go into some specific examples.

Microsoft Defender Antivirus

Microsoft Defender Antivirus, also known as Windows Defender, offers real-time protection against threats spyware, malware and viruses across:

However, only Windows 10 and later computers come with Windows Defender,3 and even so, it won’t work for all users, business-users in particular. That’s because Windows Defender doesn’t have endpoint protection and response or automated investigation and remediation. In fact, Microsoft also offers another software called Defender for Endpoint to make up for these limitations,4 but users can also use third-party apps if they prefer.

macOS Big Sur Antivirus

Similarly, Mac computers with the Big Sur operating system come with XProtect, built-in antivirus software that runs in the background without the user having to lift a finger. Apple also offers:

While these features are an essential part of any antivirus software, this built-in protection doesn’t block against adware or any PUPs (potentially unwanted programs) that have been installed without the user’s knowledge or consent. That means that some malware has been able to slip by in the past.5 Plus, Malwarebytes’ 2020 “State of Malware” report found that, compared to 2019, threats against Macs increased by over 400 percent.6 So while you can take your chances and use the Mac built-in antivirus only, redundancy is always a good thing when it comes to digital security, and protection against adware and PUPs is essential.

Free vs. Paid Antivirus Software

Like we mentioned previously, there is a lot of free antivirus software on the market, be it completely free subscriptions or free trial periods. However, these free options may have limitations such as:

Free antivirus software is certainly better than nothing, but for comprehensive protection against all of your devices, you’ll probably need to invest in a paid subscription.

If I Have A VPN, Do I Still Need Antivirus?

In a nutshell, yes, you still need a VPN even if you use antivirus software. Why? Because comparing VPNs and antivirus software is like comparing apples and oranges. While VPNs encrypt your device’s IP address and web activity, antivirus software guards against viruses and malware, so there’s no overlap in their capabilities. However, some antivirus options come bundled with VPNs, so you may be able to knock out two birds with one subscription.

how to use antivirus software

Antivirus software scans the file comparing specific bits of code against information in its database and if it finds a pattern duplicating one in the database, it is considered a virus, and it will quarantine or delete that particular file.

How The Antivirus Detects Virus?

All program files (executable) that enter a system go through the antivirus scan. Those that match the signatures are classified as viruses and are blacklisted. The other program files then pass through the Defense + HIPS ( Host Intrusion Prevention System). Here the known files would be allowed entry and would run in the system while the unknown ones, irrespective of whether they are good or bad, are sent to the Defense+ Sandbox. These would be allowed to run, but only in this restricted environment. Those that the user allows as good files would be added to the Whitelist while all others would remain in the sandbox, after which they would go to the Comodo labs for analysis.

Features of Antivirus Software

Antivirus software scans all the files that you open from the back-end; this is also termed as on access scanning. It gives a real time protection safeguarding the computer from threats and other malicious attacks.

Full System Scans

Full system scans are generally not essential when you already have an on access scanning facility. Full system scans are essential when you install antivirus software for the first time or you have updated your antivirus software recently. This is done to make sure that there are no viruses present hidden on your system. Full system scans are also useful when you repair your infected computer.

Virus Definitions

Antivirus software depends on the virus definitions to identify malware. That is the reason it updates on the new viruses definitions. Malware definitions contain signatures for any new viruses and other malware that has been classified as wild. If the antivirus software scans any application or file and if it finds the file infected by a malware that is similar to the malware in the malware definition. Then antivirus software terminates the file from executing pushing it to the quarantine. The malware is processed accordingly corresponding to the type of virus protections.

It is really essential for all the antivirus companies to update the definitions with the latest malware to ensure PC protection combating even the most latest form of malicious threat.

How to get rid of malware?

Signature-based detection – This is most common in Traditional antivirus software that checks all the .EXE files and validates it with the known list of viruses and other types of malware. or it checks if the unknown executable files shows any misbehaviour as a sign of unknown viruses.

Files, programs and applications are basically scanned when they in use. Once an executable file is downloaded. It is scanned for any malware instantly. Antivirus software can also be used without the background on access scanning, but it is always advisable to use on access scanning because it is complex to remove malware once it infects your system

Heuristic-based detection – This type of detection is most commonly used in combination with signature-based detection. Heuristic technology is deployed in most of the antivirus programs. This helps the antivirus software to detect new or a variant or an altered version of malware, even in the absence of the latest virus definitions.

Antivirus programs use heuristics, by running susceptible programs or applications with suspicious code on it, within a runtime virtual environment. This keeps the vulnerable code from infecting the real world environment.

Behavioural-based detection – This type of detection is used in Intrusion Detection mechanism. This concentrates more in detecting the characteristics of the malware during execution. This mechanism detects malware only while the malware performs malware actions.

Sandbox detection – It functions most likely to that of behavioral based detection method. It executes any applications in the virtual environment to track what kind of actions it performs. Verifying the actions of the program that are logged in, the antivirus software can identify if the program is malicious or not.

Data mining techniques – This is of the latest trends in detecting a malware. With a set of program features, Data mining helps to find if the program is malicious or not.

Why is Updating Antivirus Software So Important?

Updating antivirus is critical for the security of any system. This is because any system gets constantly threatened and attacked by new viruses every day. Antivirus updates would have latest definition files that are needed to identify and combat new viruses.

disadvantages of anti malware software


1. System Slowdown

Using an antivirus program means that a lot of resources from the memory and the hard drive is being used. As a result it can drastically slowdown overall speed of the computer. Moreover, the process of scanning can also cause lags in the network.


2. No Complete Protection

If you are using a free antivirus program, there is no guarantee that it will provide you the complete protection. Most free antivirus programs out there only offer a basic level of protection. Moreover they are capable of identifying only certain types of threats. In order for acquiring complete level of protection, you have to use a firewall as well.


3. Security Holes

When security holes are present inside the operating system or the networking software, it will provide a chance for the virus to bypass the antivirus software. Unless the user takes actions to keep it update, the antivirus software won’t be effective.


4. Limited Detection Techniques

For identifying a potential threat, there are always more than one method available. However in the case of antivirus program, it mostly executes the method of virus scanning. Basically what happens in the process of scanning is, it will try to search for the virus code patterns. Sometimes the antivirus programs can give you false alarms if the scanning matches with the normal file. Furthermore, if there are any new types of viruses the antivirus program will fail to identify it completely. That is the reason why antivirus software needs to be updated often.


5. Frequent Advertisements

Apart from premium versions of antivirus programs, through some means the free antivirus softwares needs to generate an income. Advertising is one of the ways to achieve them. Many at times these advertisements degrade user experience by showing up every time.
