Every day, thousands of people in Pakistan lose important data, money, and privacy because of viruses, malware, and online scams. Whether you are using an old Windows laptop for work or an Android phone for banking and social media, having a good antivirus is no longer optional. It is a necessity.
The good news is that you do not have to spend a single rupee to protect your device. There are some genuinely powerful free antivirus tools available in 2026 that do a solid job of keeping your phone and computer safe. In this guide, we have reviewed the best ones so you can make a smart choice without wasting time.
We will cover the top free antivirus apps for both Windows and Android, explain what features matter most, and help you figure out which one is right for your device and usage habits.
Why Do People in Pakistan Need Antivirus Software in 2026?
Pakistan has seen a sharp rise in cybercrime over the past few years. Phishing attacks through WhatsApp and SMS, fake banking apps, pirated software loaded with spyware, and malicious links shared on social media are becoming more and more common.
A lot of people in Pakistan still use older Windows versions like Windows 7 or Windows 10 without regular updates, which makes their computers more vulnerable than ever. On the Android side, many users download apps from outside the Play Store, which significantly increases the risk of getting infected by malware.
Here are some of the most common threats Pakistani users face today:
- Phishing links sent through WhatsApp and email pretending to be from banks
- Fake government websites asking for CNIC and personal information
- Pirated software and cracked apps that secretly install spyware
- Adware that takes over browsers and shows unwanted ads
- Ransomware that locks files and demands payment to recover them
A good free antivirus can protect you from most of these threats without costing you anything. Let us look at the best options available right now.
Best Free Antivirus for Windows in Pakistan 2026
- Avast Free Antivirus
Avast is one of the most downloaded antivirus programs in the world and for good reason. The free version offers real-time protection, which means it actively monitors your PC for threats as you browse, download files, or open apps. You do not have to manually scan every time.
It also includes web protection that warns you before you visit a dangerous website, which is very useful for people who may accidentally click on fake banking or government links. The interface is clean and easy to understand even for beginners.
For Pakistani users, Avast is a great choice because it works very well on older hardware. If you have a Windows laptop that is five or six years old, Avast will not slow it down noticeably.
Best for: Everyday Windows users who want solid real-time protection without spending anything.
Platforms: Windows, Android, Mac, iOS

- AVG Antivirus Free
AVG and Avast are actually owned by the same company, but they have slightly different interfaces and feature sets. AVG’s free version is particularly strong at malware detection and consistently scores well in independent lab tests from AV-Test and AV-Comparatives.
What makes AVG stand out is that it includes an email scanner in the free version, which helps catch infected attachments before they even open on your PC. It also has a file shredder tool that permanently deletes sensitive files so they cannot be recovered.
For people in Pakistan who do a lot of work through email, AVG is a practical choice.
Best for: Users who use email a lot and want extra protection against infected attachments.
Platforms: Windows, Android, Mac, iOS

- Bitdefender Antivirus Free Edition
Bitdefender is consistently rated as one of the top antivirus companies in the world by security researchers. Its free edition for Windows is extremely lightweight and uses almost no system resources while still providing excellent malware detection.
The free version does not come with many extra features — it is basically just the core engine doing its job silently in the background. But that core engine is genuinely one of the best in the industry. If you want no-fuss protection that just works without slowing your computer, Bitdefender Free is hard to beat.
Best for: Users who want a lightweight antivirus that runs quietly without interruptions.
Platforms: Windows, Android

- Malwarebytes Free
Malwarebytes works a little differently from traditional antivirus programs. Rather than providing full-time real-time protection in the free version, it is designed to be used as an on-demand scanner. You run it whenever you suspect your computer might be infected.
This makes it an excellent companion tool to use alongside another antivirus. Many experts recommend running Avast or AVG as your main antivirus and using Malwarebytes to do deep scans every week or two. Together they cover more ground than either tool alone.
Malwarebytes is also very good at removing adware and potentially unwanted programs that other antivirus tools sometimes miss.
Best for: Using alongside another antivirus for deeper threat detection and removal.
Platforms: Windows, Mac, Android, iOS

- Windows Defender (Built-in)
Many people in Pakistan overlook the fact that Windows 10 and Windows 11 come with a built-in antivirus called Windows Defender, also known as Microsoft Defender. In 2026, this tool has improved significantly and now scores very well in independent security tests.
If you are running a fully updated Windows 10 or 11 system, Windows Defender is already protecting you in the background. It provides real-time protection, cloud-based scanning, and firewall integration without you having to install anything.
It is not the absolute best option in terms of extra features, but for users who do not want to install any third-party software, it is a perfectly reliable choice.
Best for: Windows 10 and 11 users who want zero-hassle built-in protection.
Platforms: Windows only
No download needed — already installed on your PC
Best Free Antivirus for Android in Pakistan 2026
- AVG Antivirus for Android
AVG’s Android app is one of the most complete free security tools available for mobile. It includes real-time scanning that checks every app you install, a Wi-Fi security scanner that warns you if a public or home network is unsafe, and an anti-theft tracker that can help locate your phone if it gets lost or stolen.
In Pakistan where mobile banking through apps like JazzCash, Easypaisa, and bank apps is extremely common, AVG’s ability to check apps for suspicious behavior is very valuable. It can detect apps that are secretly sending your data elsewhere.
The free version does show some ads, but they are not overly intrusive and a small price to pay for the level of protection you get.
Best for: Android users who do mobile banking and want app-level threat detection.
Platforms: Android, iOS
Download from: Google Play Store — search AVG Antivirus
- Bitdefender Antivirus Free for Android
Just like its Windows version, Bitdefender’s Android app is clean, lightweight, and very effective. It focuses on doing one thing well — scanning apps and files for malware — without loading your phone with unnecessary features that drain battery.
For users with older or budget Android phones that are common in Pakistan, this is a great choice. It runs smoothly even on phones with 2 GB or 3 GB of RAM without noticeable slowdowns.
Best for: Users with older or budget Android phones who want lightweight protection.
Platforms: Android
Download from: Google Play Store — search Bitdefender Antivirus Free
- Avast Mobile Security
Avast’s Android app goes beyond basic virus scanning. The free version includes a privacy scanner that checks your installed apps and flags which ones have access to your contacts, camera, microphone, or location without a clear reason. This is especially useful for catching shady apps that overstep their permissions.
It also includes a call blocker for spam calls and an app lock feature that lets you protect specific apps with a PIN or fingerprint. These extras make it a solid all-in-one security tool for Android users.
Best for: Users who want privacy-focused protection and extra app management features.
Platforms: Android, iOS
Download from: Google Play Store — search Avast Mobile Security
- Kaspersky: Virus Removal Tool (Mobile)
Kaspersky has long been known for extremely accurate malware detection. The mobile version offers a clean interface with real-time protection and a strong scanning engine. One of its standout features is anti-phishing protection that works inside your browser to flag dangerous links before you click them.
This is particularly helpful for Pakistani users who frequently encounter phishing links in WhatsApp groups pretending to be from FBR, BISP, or banking institutions.
Best for: Users who want strong phishing link protection on Android.
Platforms: Android
Download from: Google Play Store — search Kaspersky Security & VPN
Free vs Paid Antivirus — What Is the Real Difference?
This is a fair question. Free antivirus tools are good but they do come with some limitations compared to paid versions. Here is a simple breakdown:
Free antivirus tools typically include basic malware scanning, real-time protection in some cases, web protection against dangerous sites, and on-demand scanning. These cover the needs of most everyday users perfectly well.
Paid antivirus tools add things like a VPN for safe browsing on public Wi-Fi, password managers, parental controls, advanced ransomware protection, identity theft monitoring, and customer support. These extras are genuinely useful but most home users in Pakistan do not strictly need them.
The honest answer is that for personal use, a good free antivirus is enough. If you run a small business, handle sensitive financial data, or manage multiple devices for a family, a paid plan starts to make more sense.
How to Choose the Right Antivirus for Your Needs
Choosing the right antivirus depends on a few simple factors. Think about these before you download anything:
What device are you protecting? If it is a Windows PC, Avast, AVG, or Bitdefender are all excellent. If it is an Android phone, AVG or Avast mobile give the best all-around free experience.
How old is your device? Older phones and laptops need lightweight options. Go for Bitdefender Free on both Windows and Android — it uses the least system resources.
Do you do mobile banking? Then prioritize an antivirus with app-level scanning like AVG or Avast Mobile Security.
Do you often click links in WhatsApp or SMS? Kaspersky’s phishing protection is your best friend in this case.
Do you want to set it and forget it? Windows Defender on Windows or Bitdefender Free on Android will protect you silently in the background with minimal interaction needed.
Tips to Stay Safe Online in Pakistan — Beyond Antivirus
An antivirus is an important layer of protection but it is not the only one. Here are some extra habits that will keep you much safer:
Always download apps from the official Google Play Store on Android. Avoid installing APK files from unknown websites unless you are absolutely sure of the source. Keep your Android and Windows systems updated — most security patches are delivered through updates. Never click on links in WhatsApp, SMS, or email that ask you to verify your CNIC, bank account, or Easypaisa wallet. Government agencies never ask for sensitive information this way. Use a strong PIN or password on your phone and enable two-factor authentication on important accounts. Be careful about which apps you give permission to access your camera, microphone, and contacts. If an app does not need those permissions for its function, deny them.
Combining these habits with a good free antivirus gives you a solid layer of protection against the vast majority of threats that Pakistani users face today.
Frequently Asked Questions
Question 1: Which is the best free antivirus for Windows in Pakistan?
Avast Free Antivirus and AVG Antivirus Free are both excellent choices for Windows in Pakistan. They provide real-time protection, web protection, and regular updates without costing anything. If you want something even more lightweight, Bitdefender Free Edition is ideal.
Question 2: Is there a good free antivirus for Android phones in Pakistan?
Yes. AVG Antivirus for Android and Avast Mobile Security are both highly rated free options. They offer real-time app scanning, Wi-Fi security checks, and anti-theft features. Both are available for free on the Google Play Store.
Question 3: Is Windows Defender good enough for protection in 2026?
Yes, Windows Defender has improved significantly and is now considered a solid baseline protection for Windows 10 and 11 users. It is not the most feature-rich option, but it handles everyday threats well and does not require any installation.
Question 4: Can a free antivirus protect me from phishing in Pakistan?
Most good free antivirus tools include basic web protection that can catch known phishing sites. Kaspersky and Avast are particularly strong in this area. However, the best defense against phishing is awareness — never click suspicious links even if your antivirus does not immediately flag them.
Question 5: Should I use more than one antivirus at the same time?
Running two full antivirus programs at the same time on Windows is not recommended because they can conflict with each other and slow down your PC. The exception is using Malwarebytes alongside your main antivirus — Malwarebytes is designed as a companion tool and works well alongside Avast or AVG without causing conflicts.
