What is the best antivirus software for both PC and mobile?

I recommend you to use Norton's antivirus software. It supports almost every device and can cover multiple devices. Protect your kids from the unexpected browsing experience. Ensure high protection for you.

Bitdefender is software for entry-level users. Very easy to use and serve high performance. Kaspersky is also best for free use. You will get a very good experience using it. 

I picked my best choice above; all of those are awesome to protect you. But it can be more useful to you according to your demand. So I write down some facts here to help you to find out the best fitting software for you.

Decide what features you need. Basic antivirus protection is almost enough, but many important features are not included here. While using public Wi-Fi networks, you should choose a product that includes a VPN. If you have kids, you need parental controls to protect them from vulgar things. Norton 360, provides these more advanced features.

Consider the operating system: Do you use Windows, IOS, or Android? Then identify which software is suitable for your operating system. 

How many devices do you need to protect? You certainly have more than one device that requires antivirus software for protection. Almost all brands offer discounts for multiple licenses. Find out your best suit. 

Free trial and money-back guarantee. There are several brands on this list that offer a free trial. Some offer a free version of the software. You should take a look for a money-back guarantee and their return policy.

The best free antivirus software for PC

All paid software offers a vast amount of features to secure your device. They mainly offer all the advanced features you need. But it sometimes needs to basic scan to verify your security, and then the free version is ok.

Many users don't want, or can't afford, to pay for all extra features. They just want to have their computers protected from malware and other threats without making to pay for it. You can use Kaspersky for free. It offers a few useful features free of cost.

How to choose the best antivirus software for PC and mobile devices?

First of all, you should figure out your need before you buy any antivirus software. If you want to store your file in the cloud, then look for it. If you want to ensure safe internet for your children then consider midrange antivirus, most of them include parental control.

What type of operating system are you using; it should be considered. Determine how many devices you want to cover and is it for home or office. There are a few things to consider I point it below. 

Strong protection

Make sure the product can protect your device against the most advanced malware threats. Not only viruses, but also spyware, rootkits, ransomware, and any other issues that can harm your device.

High-quality features

Tons of features always don't able to give you proper value. Identify the quality of those features.

Speed and efficiency

The best antiviruses are lightweight and run smoothly even on older or slower computers. So identify speed and efficiency before buying Antivirus software.

Good value

It can be a big investment to set up antivirus software for your device. I considered all relevant factors such as how many devices are covered, and whether or not there's a free trial or money-back guarantee - I feel that all of those top antiviruses provide great value for you.


There is no need to get extra pressure while using antivirus software. Because software providers always try to make your experience better. So find it out.

Useful tools

Don't be stuck into older models of software. There are tons of new tools are including nowadays software providers.  Some useful tools like:

Virtual Private Network (VPN) 

A secure internet connection that protects your online activity and hides your IP address.

Password management

This is for storing login information and creating secure passwords.

Parental controls

Advanced tools that keep your kids protected.


Antivirus service does not depend on price, it depends on quality and performance. So always try to find out which antivirus is best for you.  Otherwise, the cheapest plans always do not make worth for you as well as higher price software. You have to decide why you are using this software because it can be useless some advanced features to you. Then why do you make costs to get such features?

Frequently asked questions

Q: What factors should I consider when choosing antivirus software for my PC and mobile?

A: When choosing antivirus software for your PC and mobile devices, it's important to consider the following factors:

  1. Security Features: Look for antivirus software that offers a wide range of security features, such as real-time scanning, malware detection, phishing protection, firewall, and secure browsing.

  2. System Impact: Consider the impact of the antivirus software on your system's performance. Opt for software that has minimal resource usage and doesn't slow down your device.

  3. Compatibility: Ensure that the antivirus software is compatible with your operating system (e.g., Windows, macOS, Android, iOS) and device specifications.

  4. Ease of Use: Choose software that has a user-friendly interface and intuitive controls, making it easy to navigate and configure settings.

  5. Updates and Support: Check if the antivirus software provides regular updates to stay protected against the latest threats. Additionally, consider the availability of customer support and the responsiveness of the company in addressing user concerns.

  6. Reputation and Reviews: Research the reputation and reviews of the antivirus software. Look for independent lab test results and user feedback to gauge its effectiveness and reliability.

  7. Price and Licensing: Evaluate the pricing options and licensing terms of the antivirus software. Determine whether it offers a free version, trial period, or subscription-based model, and choose the option that best fits your budget and needs.

Q: Are free antivirus programs as effective as paid ones?

A: Free antivirus programs can offer basic protection against common threats, but they typically have limitations compared to paid versions. Here's a breakdown of their differences:

Free Antivirus Programs:

  • Basic Protection: Free antivirus programs generally offer essential features like real-time scanning, malware detection, and basic firewall protection.
  • Limited Features: They often lack advanced features like ransomware protection, secure browsing, password managers, or VPNs.
  • Advertisements and Upgrade Prompts: Free versions may display ads or prompt you to upgrade to their paid versions.
  • Less Support: Free programs may have limited customer support or slower response times.
  • Lower Detection Rates: Paid antivirus software often has more robust threat detection capabilities and can detect and remove a broader range of malware.

Paid Antivirus Programs:

  • Comprehensive Protection: Paid antivirus programs typically offer a wide range of security features, including advanced threat detection, ransomware protection, secure browsing, password managers, and more.
  • Enhanced Performance: Paid versions are often optimized to have minimal impact on system performance.
  • Technical Support: Paid programs usually provide better customer support, including phone, chat, or email assistance.
  • Regular Updates: Paid software receives regular updates to combat new and emerging threats, keeping your devices protected.
  • Higher Detection Rates: Paid antivirus programs generally have higher detection rates, thanks to their more advanced scanning algorithms and databases.

Ultimately, the decision between free and paid antivirus software depends on your specific needs, budget, and the level of protection you require.

Q: How often should I update my antivirus software?

A: Regularly updating your antivirus software is crucial for maintaining its effectiveness. Here are some guidelines for updating your antivirus software:

  1. Automatic Updates: Enable automatic updates within the antivirus software's settings. This ensures that you receive the latest virus definitions, security patches, and program updates without manual intervention.

  2. Frequency: Antivirus software typically checks for updates at least once a day. However, some programs may have more frequent update schedules, especially when dealing with critical security threats.

  3. Real-Time Updates: Modern antivirus software often incorporates real-time protection that continuously monitors your system for new threats. Real-time updates occur automatically in the background as the software detects new virus signatures or behavioral patterns.

  4. Offline Computers: If you have a computer that is not always connected to the internet, make sure to update the antivirus software manually whenever you go online or at least once a week to ensure it has the latest protection.

  5. Check for Program Updates: In addition to virus definition updates, antivirus software may release periodic program updates that introduce new features or improve performance. Check for these updates within the software's settings or on the vendor's website.

By keeping your antivirus software up to date, you enhance its ability to detect and protect against the latest threats, ensuring your devices are secure.

Q: Can antivirus software detect and remove all types of malware?

A: While antivirus software is designed to detect and remove various types of malware, it's important to note that no antivirus program can guarantee 100% protection against all threats. Here's why:

  1. New and Unknown Threats: Antivirus software relies on virus definitions and behavioral patterns to identify malware. If a new or unknown type of malware emerges, the antivirus may not immediately recognize it until its signature or behavior is added to the software's database.

  2. Zero-Day Exploits: Zero-day exploits are vulnerabilities in software that are unknown to the software developers. Attackers can exploit these vulnerabilities before the software vendor releases a patch or update. Antivirus software may not be able to detect or prevent such attacks until a patch is available.

  3. Polymorphic Malware: Polymorphic malware can change its code or behavior to evade detection by antivirus software. It can alter its signature with each infection, making it challenging for antivirus programs to keep up with its variants.

  4. Advanced Persistent Threats (APTs): APTs are sophisticated and targeted attacks that often evade traditional antivirus software. They are designed to remain undetected for an extended period, making them difficult to detect and remove.

To enhance your protection against malware, it's important to follow best practices such as keeping your operating system and software updated, avoiding suspicious downloads or email attachments, and practicing safe browsing habits.

Q: Can antivirus software slow down my computer or mobile device?

A: Antivirus software has the potential to impact system performance, although modern antivirus programs are designed to minimize resource usage. Here's why antivirus software can sometimes slow down your computer or mobile device:

  1. Scanning and Resource Usage: Antivirus software performs real-time scans of files, downloads, and web pages to detect and prevent malware. These scans consume CPU resources, memory, and disk access, which can lead to a temporary slowdown, especially on older or low-spec devices.

  2. Background Processes: Antivirus software typically runs background processes to continuously monitor system activity for potential threats. While these processes are designed to be lightweight, they still consume some system resources.

  3. Scheduled Scans: Antivirus programs often schedule regular system scans, which can temporarily slow down your device while the scan is in progress.

To minimize the impact on system performance, consider the following steps:

  • Configure scheduled scans during periods of low activity or when you're not actively using the device.
  • Exclude trusted files, folders, or applications from scanning if they don't pose a significant security risk.
  • Opt for antivirus software known for its low system impact and resource usage.
  • Ensure your computer or mobile device meets the recommended hardware requirements for the antivirus software.
  • Close unnecessary background applications or processes that consume system resources.

By following these practices, you can strike a balance between maintaining system performance and keeping your devices protected with antivirus software.

Q: Can I install multiple antivirus programs on my computer or mobile device?

A: It is generally not recommended to install multiple antivirus programs simultaneously on your computer or mobile device. Here's why:

  1. Performance Issues: Running multiple antivirus programs simultaneously can lead to conflicts and performance issues. Antivirus software often includes real-time scanning and monitoring features that constantly check for threats. When multiple programs are active, they may conflict with each other and consume additional system resources, resulting in reduced performance.

  2. False Positives: Having multiple antivirus programs increases the chances of false positives, where benign files or legitimate applications are flagged as malware. This can lead to unnecessary alerts, quarantine, or deletion of harmless files, causing inconvenience and potential data loss.

  3. Compatibility Issues: Antivirus software is designed to work independently and integrate with the operating system. Installing multiple antivirus programs can result in compatibility issues, including conflicts with system processes, drivers, or other security software.

Instead of using multiple antivirus programs, consider the following alternatives:

  • Choose a reputable antivirus program that provides comprehensive protection.
  • Supplement your antivirus software with additional security layers such as firewalls, anti-malware tools, or browser extensions that focus on specific threats.
  • Regularly update your antivirus software to ensure it has the latest virus definitions and security patches.

Remember, maintaining a single, reliable antivirus solution and practicing safe computing habits is generally more effective than relying on multiple conflicting programs.

Q: How often should I perform a full system scan with my antivirus software?

A: Performing regular full system scans with your antivirus software is essential to ensure comprehensive protection. However, the frequency of these scans depends on your computer usage and risk tolerance. Here are some guidelines:

  1. Weekly or Monthly Scans: It is generally recommended to perform a full system scan at least once a week or once a month. This allows the antivirus software to thoroughly check all files and folders on your computer for any hidden or dormant threats that may have evaded real-time monitoring.

  2. After System Changes or New Installations: Perform a full system scan after making significant changes to your system, such as installing new software or updates. This helps ensure that your computer remains free from any potential malware or compromised files.

  3. Suspicious Activity or Detected Threats: If your antivirus software detects a specific threat or suspicious activity, initiate a full system scan immediately to identify and remove any related malware.

  4. Customized Scans: Some antivirus programs offer the option to perform targeted scans on specific files, folders, or external devices. If you have concerns about a particular area of your system, use customized scans to focus on those areas.

Keep in mind that full system scans can be resource-intensive and time-consuming. Therefore, schedule the scans during periods of low activity or when you're not actively using your computer to minimize any disruption.

Q: How can I ensure that my antivirus software is not a fake or rogue program?

A: With the rise of online scams and malicious software, it's important to verify the authenticity and reliability of antivirus software to avoid installing fake or rogue programs. Here are some steps to ensure you are using legitimate antivirus software:

  1. Choose Reputable Sources: Download antivirus software only from trusted sources, such as official vendor websites, reputable app stores, or authorized resellers. Be cautious of downloading software from unfamiliar or suspicious websites, as they may distribute counterfeit or malicious programs.

  2. Research the Vendor: Conduct research on the antivirus software vendor to verify their reputation, longevity, and customer reviews. Look for established companies with a track record of providing reliable and effective security solutions.

  3. Check Digital Signatures: Authentic antivirus software is often digitally signed by the vendor to ensure its integrity. Before installing the software, check the digital signature to confirm its authenticity. Right-click on the software installer, select Properties, navigate to the Digital Signatures tab, and verify the signature details.

  4. Malware Scans: Before installing antivirus software, perform a malware scan on the installer file using a different security tool. This additional scan can help detect any potential threats embedded in the software package.
