4 Best Antivirus Options For Software Developers

4 Best Antivirus Options for Software Developers Try the latest security solutions to block all cyber threats

892

X

We have discussed the best antivirus for software developers that allow for easy customization and flexibility. 

Marking a specific folder as safe is a great way to manage development when you have a running antivirus. 

Unlike other software discussed in this article, Windows Defender comes pre-installed on your Windows PC and remains a great option that allows for easy tweaks. 

Using antivirus (AV) software remains a best practice in computer maintenance. It keeps viruses at bay and signals you when there is an intrusion into your computer.

In this day and age, you dare not browse the internet without some form of protection. Browsing the web means you have to interact with other connected devices, you may share files and resources, and you might have a malicious user try to compromise your network and steal critical data. These and more are reasons why you need an antivirus.

But from a developer’s viewpoint, an AV is not always the white angel. In many testing scenarios, they may stop critical programs from running, or increase the testing duration. False positives become a nightmare, and shutting the AV may be the solution to running a smooth software test. Learn more on our guide for best antiviruses without false positives.

In this article, we like to explore some of the best antivirus software for developers.

Should developers have antivirus software on their machines?

There are no reasons why software engineers shouldn’t have antivirus software installed on their computers, and there are compelling arguments for this.

However, for this protection software to not be a bother during development, keep the following in mind:

Set up your antivirus software to recognize the development folder (the one associated with the code repository) as a trustworthy folder.

Ensure that files transmitted through email have a different extension to get past most email clients’ attachment regulations. Many antivirus programs will warn you if you open an executable file.

For development, use a virtual machine. This has a performance cost, but the benefit is that if anything goes wrong, all you have to do is delete the VM or restore it to a week-old snapshot and execute a git pull. It’s a lot simpler to accomplish this than to retain actual machine snapshots, particularly when the hardware is changing.

If these elements apply to your situation, then having good antivirus software will surely have a great impact in the long term.

What are the best antivirus apps for developers?

Linux, as well as Mac and Windows machines, are all supported in this AV.

ESET also has a lot of configuration options, which may appeal to developers, but it may be difficult for beginners to grasp in certain areas. So, developers will be able to use these alternatives to get the most out of their software development process.

This AV is reliable. It’s also worth mentioning that Live Guard, an additional layer of cloud analysis to identify freshly discovered threats, has just been added to the suite’s protections.

It also includes some intriguing extras, such as the password manager and a safe, encrypted file vault, which are likely to be quite beneficial to software developers.

Additional features:

Improved network inspector

Firewall

Anti-Phishing

ESET Internet Security

Get the latest security solution to protect your computer at all times.

To begin with, the overwhelming number of functions included in Bitdefender is quite astounding. Even if you get Bitdefender Antivirus Plus, you will receive online banking protection with Safepay, which is a secure browser that protects you from all perspectives.

A vulnerability scanner, password manager, and a high-quality VPN with a daily limit of 200MB are also included in this package.

Bitdefender is very user-friendly, with a professional and well-balanced UI that’s appropriate for total novices as well as specialists looking to adjust things. This flexibility is ideal for a developer who has to alter settings to enable specific applications.

The antivirus includes all of the above and capabilities to increase PC speed and locate lost mobile devices.

Bitdefender Total Security is the company’s flagship product. It includes various PC maintenance tools and support for Android and iOS devices, Mac, and Windows PCs – in other words, it’s a one-stop shop for your whole family’s online security requirements.

Regardless of the Bitdefender edition, you select, you’ll receive a lot of value for your dollar, especially if you have a lot of devices. 

Additional features:

Fast scan

Configurable interface

Advanced threat defense

After installation, there is not much to do; Malwarebytes operates in the background to protect you without you having to do anything.

Malwarebytes’ primary Scan tool swiftly scans your startup items, RAM, and essential file system regions.

A distinct Custom Scan lets you choose which objects to scan, including individual files, and allows you some flexibility over how they function (such as whether to scan within archives and what to deal with possibly harmful applications). This feature is essential for the developer who will want to mark some folders as safe. 

Malwarebytes also includes basic URL filtering, detecting and blocking fraudulent link attempts. This secures all of your applications at the network level and does not need browser add-ons.

Additional features:

Cloud management console

Threat hunting, isolation, recovery

Brute Force Attack Prevention

Ransomware, zero-day exploits, phishing protection

Microsoft Defender antivirus does not seem to get the respect it deserves for its security features. This tool has constantly evolved since its release in Windows Vista.

Microsoft Defender offers a comprehensive variety of options for scanning, including a full system scan, a fast scan, a custom scan to examine specific folders and files, and a boot scan to eliminate the most persistent threats before Windows completely boots.

Defender’s Controlled Folders function adds a second degree of security. When you enable this feature, it automatically prevents unauthorized applications from reaching essential folders (these folder lists can always be updated). This is a practical method of safeguarding test software.

Antivirus isn’t the only thing to look at when it comes to Windows Defender; there are plenty more. The firewall is most likely at the top of the list. 

This firewall performs an excellent job of defending you from incoming network threats, but it’s less concerned with managing outward access; if a program has administrator privileges, it may tweak the firewall by adding its own rules.

You may wish to create unique rules for some of your test applications.

Additional features:

System performance reports

Real-time threat detection

Hardware security

⇒ Get Windows Defender

Regardless of your computer use habits, we recommend you employ an antivirus to keep you safe. However, we understand that it may come with some drawbacks for a developer, notably the considerably slower times it takes to test and run applications. Still, these do not outweigh the many benefits.

We have not made this list in any particular order, but we have shed some light on some of the antiviruses that allow flexibility and customization. These are great for developers who may need to tweak some settings to run programs.

If you want to explore further and seek out some free solutions, you should read our guide on 5+ truly free antivirus software.

4 Best Caller Name Announcer Apps For Android

Imagine this – you are playing your favourite title on your Xbox One when the phone rings in the other room and you don’t want to leave your game, just to check out who’s calling. It is during moments like these that you wished your Android smartphone to be a bit wiser in telling who’s calling without actually picking it up. On iPhone, you can enable Siri to speak out the caller’s name for you but, on Android, you will need a third party call announcer app. Thankfully, there are certain third-party caller name announcer apps that can speak out the name of your callers. Not only caller names but messages can be read out too. So, here is a list of the 4 best caller name announcer apps for Android:

1. Caller Name Talker

The app also provides a lot of options for the readout functions. You can set the delay time for the alerts, put in custom messages before and after the names, lower the ringtone volume while the alert plays and more. The app uses the built-in Android text-to-speech engine to voice the caller or SMS sender ID. You also get gestures like shake your phone to stop caller name alert while the phone rings. Overall, the app works well and we didn’t notice any major bugs. There’s a paid version dubbed Talk Caller Name PRO that is ad free but it hasn’t been updated with features of the latest free version. So, it is wise to stick to the free version until the updated Pro version comes out.

2. Caller Name Talker

First of all, this is a completely different app that happens to have the same name as the one mentioned above. With a not-so-good UI, it has all the basic features a caller name speaker app should have. You can let your phone announce names of saved contacts as well as unknown numbers too. It can also read your SMS alerts along with its content. There are various customizable settings like one tap to disable/enable the functions, turn on/off the voice alert over the ringtone and text-to-speech settings. You can also put in custom messages after a caller’s name.

Unfortunately, it lacks most of the additional features that the previously mentioned app packs. Having said that, this app functions efficiently and is a good one if you want a simplistic and uncomplicated caller name talker app.

Install: (Free)

3. Caller Name Announcer Pro

The app lets you play with the audio settings like changing the pitch settings and voice speed, as Caller Name Announcer Pro uses Android’s built in text to speech library. The caller ID  function works very well, showing you caller information of unknown contacts, like Truecaller. Sadly, the customisation options are pretty limited and we suggest you to go for this only if you want caller ID features packed in a caller name announcer apps.

Install: (Free)

4. Speaking SMS & Call Announcer

Another nifty feature is that it allows you to choose between reading an unknown phone number or simply reading “unknown”. The “Filter Contact” feature is another notable feature that lets you to assign a specific list of contacts to be announced. Also, you can deactivate the app for a specific time period with its “No alert schedule”. Try this out for its sheer list of features and a well laid out UI.

Install: (Free)

4 Best Data Processing Frameworks

Big data is one of the hottest buzzwords and trends in technology for quite some time now. However, beyond the buzz of the media, Big data is a fundamental technology in building future businesses and sustainable enterprises. It is what allows businesses to better understand their clients and make better decisions based on that understanding, it also allows decision makers to predict and understand failures, errors, threats as well as opportunities and hence create more sustainable systems in return. It’s true that data has existed for as long as we could remember, but the exponential increase in volume, variety, and velocity of that data is what earned it the name of Big Data. We generate quintillion bytes of data every day, more than 500 thousand photos are being shared on Snapchat, 4 million videos being viewed by users and 3+ million search queries being conducted on Google in a single minute. The sheer volume of valuable insights in that enormous amount of data creates the need for Big Data frameworks, to manage and analyze the data with the resources at hand.  

Hadoop

Hadoop is an Apache open source framework for managing and processing datasets. Hadoop uses computer clusters and modules that are designed to be fault-resistant. Based on the belief that hardware will fail, at one point or another, it replicates the data and copies it to another node in the cluster so that if a failure took place, the data could be retrieved through the other node and saving the hustle of data inconsistency. That is not the only benefit that Hadoop offers, though, Apache Hadoop is scalable which is an important requirement in the Big Data world, as users should have the ability to expand their infrastructure and distribute a large amount of data over multiple servers that could be potentially working in parallel. Not only that, but it is also a fast and flexible framework, the way Hadoop maps the data on the clusters empowers data processing and make it faster. Hadoop comes with four modules: Hadoop Common, Hadoop Distributed File system, Hadoop YARN (Yet Another Resource Negotiator) and Hadoop MapReduce. While Hadoop is a widely known and loved framework, there are few cons to using Hadoop such as lack of preventive measures as the default of security measures in Hadoop is being disabled, so scientists and users should always keep that in mind while working with sensitive data. Also, it’s hard to use for small data, so it’s almost only fit for usage at large companies or entities that generate or possess a large amount of data.  

Apache Spark

Spark is another amazing product made by Apache for batch processing. It’s a fairly easy to use framework, that enables users to write applications in Java, R, Python, Node Js and Scala. Although, an ideal situation occurs if the developer knows or tends to

Apache Storm

Storm is another framework offered by Apache for data processing, specifically, real-time processing. It is simple and can be used with any programming language, which allows you to use it with your favorite language and it is said to be fun to use as well. The core idea of Storm is defining certain small and discrete operations which creates a topology that functions as a pipeline for transforming the data. Storm is used for real-time analytics, continuous computations, online ML and much more. According to Apache,” a benchmark clocked spark at over million tuples processed per second per node”. Spark is also scalable and fault-tolerant.  

Apache Samza

Apache Samza is a powerful framework for asynchronous stream processing in real-time, which utilizes Apache Kafka for messaging and Hadoop YARN for fault tolerance, security and resource management. Samza offers a suite of great features such as a simple API that is comparable to MapReduce, processor isolation, durability, scalability and the fact that is Pluggable and lets you run Samza with other execution environments. The framework is made to handle many gigabytes per partition i.e. large amounts of states. It snapshots and restores processor’s state and is capable of restoring to a consistent snapshot upon restarting. Samza is best used for filtering, joins, distributed RPC and reprocessing.  

Wrap-up

There is also Apache Flink which we can’t go by without mentioning, it’s a powerful framework for both real-time and batch modes. It offers many high-level functionalities while being similar to MapReduce and is absolutely stunning when it comes to performance. The key point in comparing the frameworks and the main criterion is the environment and application that they will be used for, as the nature of the data and the environment shifts the need from one framework to another. Also, the use of a wrong framework for a situation would result in wasted resources.

It’s a fairly easy to use framework, that enables users to write applications in Java, R, Python, Node Js and Scala. Although, an ideal situation occurs if the developer knows or tends to learn Node Js for a better implementation of Apache Spark. Thanks to its DAG scheduler, physical execution engine, and query optimizer, it is hundred times faster than Hadoop is. Spark is perfect when it comes to machine learning too, but it then requires a cluster manager and a distributed storage system. Spark can be used as a standalone framework or can be used in conjunction with other frameworks as it supports the integration with Hadoop. Apache Mesos, Cassandra, HBase and kurbenetes which makes it ideal for most types of integrations, whether on an individual small scale or a large scale for businesses. Spark is based on a type of data structures known as RDD or Resilient Distributed Dataset. It is a read-only set of items that are distributed over the whole cluster of machines in the system. RDD makes the system fault-resistant as well and prevents the loss of data in cases of failures. Spark comes with a stack of libraries that empowers its functionality even more, that includes Spark SQL, Spark Streaming, MLib, Graphx. The spark code is reusable as well which makes it even friendlier and easier to use. However, there are cons to using Spark too, as it’s not too small-data friendly when it’s used with Hadoop either, and the RDD structure poses a high memory cost in return for the performance.Storm is another framework offered by Apache for data processing, specifically, real-time processing.

Also, the use of a wrong framework for a situation would result in wasted resources.
