AVG vs Avast: What is the Difference 2025?
AVG and Avast are two of the most widely-used antiviruses, mainly because of their free plans. They claim to provide airtight security and top-notch privacy, but I wasn’t convinced since both contenders are owned by the same parent company that was found to be secretly selling s’ data.
Despite that, I was curious to see which antivirus is better overall. I tested them rigorously across multiple categories and found that Avast won but only by a slim margin. AVG had better detection scores and system performance but Avast outshined in optimization tools, extra features, and ease of use.
However, I can’t recommend either because of their privacy issues in the past. Instead, I recommend using a reliable antivirus like Norton because it provides perfect protection at a competitive price.
No Time? Here’s a 1-Minute Summary of Category Winners
AVG provided me with better detection scores but lost out in most other categories, including system performance, optimization tools, and more. Overall, it was a close competition, but Avast took the lead, albeit only by a small margin.

1. Virus Scanner — AVG Provides More Accurate Detection
After rigorously testing both antiviruses, AVG gave me significantly better protection than Avira. AVG offers a range of scan options:
- Smart Scan — Quickly scans the most critical areas of your PC’s hard drive.
- Deep Scan — Performs a full scan of your PC and checks the entire hard drive.
- File/Folder Scan — Scans specific folders for malware.
- Boot-Time Scan — Runs a scan during boot-up to remove viruses before launch.
- USB/DVD Scan — Scans removable hard drives, including USBs and external hard drives.
- Performance Scan — Scans your system for optimization issues and provides recommendations.
I recommend running the Deep Scan if you want to thoroughly rid your PC of viruses. While Smart Scan is more popular because it performs a scan quickly, it doesn’t check every nook and cranny of your hard drive. I wasn’t completely satisfied with the Deep Scan’s imperfect results, especially when I’m used to Norton’s 100% detection rate.
AVG’s Deep Scan detected 99.7% of the malware I had planted on my computer. However, it took more than 50 minutes to complete. While AVG’s score was much better than the industry average of 97%, it still doesn’t provide perfect protection.

While it gave me an excellent detection score, AVG missed a couple of zero-day malware and also falsely flagged 5 safe files. As a result, I had to manually deselect those files and mark them as safe.
Like AVG, Avast also offers 6 scan types:
- Full Scan — Scans your whole system
- Targeted Scan — Allows you to select files and folders you want to be scanned
- Boot-Time Scan — Scans your computer before the operating system boots up
- Quick Scan — Scans the most at-risk sections of your device
- Smart Scan — Checks for outdated programs, dangerous browser extensions, and performance issues.
- Custom Scan — Lets you choose which type of scan to run, when to run it, and what to search
I ran the full scan, and it gave me a decent detection score of 98.8%, falling behind AVG by a slim margin. However, I was happy that it took only 23 minutes, almost half of AVG’s full scan time.
Avast gave me 15 false positives, and it was quite time-consuming to scroll through the list of viruses to mark safe files. Overall, AVG provides better protection and doesn’t give many false positives.
Virus Scanner Winner: AVG
2. Real-Time Malware Protection — AVG Provides Better Real-Time Protection
AVG gave me a better real-time protection score than Avast, detecting 99.85% of all viruses in real-time compared to Avast’s 99.5%. To conduct the real-time protection test, I ed 500 virus samples, including URLs embedded in scam emails.
I was delighted to see that AVG blocked all infected files I had planted on my PC. However, it failed to detect 1 malicious link in a scam email. On the other hand, Avast failed to detect 2 infected files and 1 malicious scam URL.
After a lot of research, I finally discovered why AVG was so much better than Avast at detecting viruses in real-time. AVG uses AI technology to enhance its detection capabilities, especially against zero-day viruses that haven’t been cataloged. Even so, it still missed out on well-hidden zero-day malware, which top antivirus suites like Norton managed to detect.
AVG also features phishing protection, but I was disappointed by its results. It identified only 85% of phishing attacks when I ran over 500 URLs on my testing machine. In comparison, Avast detected 86% of phishing domains, slightly better than AVG but still not on par with top antiviruses in the industry.
Real-Time Malware Protection Winner: AVG
3. System Performance — AVG Is Lighter but Still Doesn’t Provide a Lag-Free Experience
AVG was lighter on my PC than Avast. It gave me a relatively lag-less experience but only when I didn’t do resource-heavy tasks on my PC during the scan.
To conduct my system performance test, I observed how much each antivirus’s full scan slowed down my PC. To start, I simultaneously launched 10 websites while running a full scan and noticed how long it took the websites to load as compared to without a scan.
The batch of websites opened in less than 2 seconds without a scan. However, it took 4 and 7 seconds to open the same batch while running AVG’s and Avira’s full scans, respectively. Similarly, opening resource-heavy software like MS Office and AutoCAD was 11% and 16% while running AVG’s and Avira’s full scans, respectively.
AVG felt lighter on my PC overall. When I ran its full scan, however, I noticed some lag while I surfed the internet on multiple tabs simultaneously. I could stream YouTube and Netflix without any problems, though. In contrast, Avast felt much heavier on my PC, even without a scan. I had difficulty multi-tasking on multiple tabs all at once, and the lag was worse overall.
In summary, AVG is less resource-intensive than Avast, but you still can’t do heavy tasks on your PC like installing a large program with its scan running in the background. If you’re looking for a more lightweight antivirus, I recommend going for Bitdefender, as it hosts a cloud-based infrastructure that doesn’t weigh down on your PC.
System Performance Winner: AVG
4. VPN — Avast’s VPN Keeps You Safe from Prying Eyes
After comparing each contender’s VPN, I recommend Avast’s because it offers better speeds on mid-range servers. Both AVG and Avast are equipped with a decent VPN, but, unfortunately, only on their top-tier plans. In of being able to access your home content and speeds, both gave me similar performance.
Avast’s SecureLine VPN hosts 700+ servers in over 35 countries. While traveling overseas, I had no trouble accessing the following streaming s:
- Netflix
- Amazon Prime Video
- Hulu
- HBO Max
- Disney+
Avast has a decent server network and unlocks a wide range of streaming platforms, but it doesn’t beat some of the standalone VPNs in the industry.

Although SecureLine gave me great speeds on nearby servers, it struggled to keep up on distant servers. I got speed drops of up to 50% on distant servers, and my streaming experience was frequently punctuated by buffering. If you’re an avid streamer, I recommend trying out ExpressVPN because it provides an extensive server network, superior streaming capabilities, and blazing-fast speeds.
AVG’s SecureVPN was decent and allowed me to access:
- Netflix
- Amazon Prime Video
- Disney+
However, I couldn’t access my Disney+ and HBO Max s and kept getting an error message. I got good speeds on nearby servers, but, like Avast, AVG also suffered from slow speeds on distant servers.

The main reason why Avast wins this round is that it provides better speeds on mid-range servers than AVG. However, I would be cautious using both contenders’ VPNs, as they have been caught storing and selling personal information, including email addresses, location, and time stamps.
Overall, Avast’s VPN is better, but I wouldn’t use either antivirus because of privacy concerns. Instead, if you want a VPN build-in to your antivirus package I would suggest one of these options.
VPN Winner: Avast
5. s — Both Antiviruses Lack Features
I was extremely disappointed to learn that neither contender provides an essential feature like s in their plans (even the top-tier plans). s aren’t an exotic feature but are necessary for parents who want to prevent their children from accessing inappropriate websites and apps.
If not having s is a deal-breaker, you can
Norton gives you total access to your child’s online and offline activities. You can block websites, videos, and apps, set up screen time restrictions, and even track location.
VPN Winner: None
6. Firewall — Avast’s Firewall Provides Comprehensive Protection and Is Easy to Use
After using AVG’s and Avast’s firewalls, I was impressed by the robust security they offer. However, after careful consideration and multiple detection tests, Avast’s firewall leaped ahead in the contest. It offers comprehensive security and lets you take full control of your incoming and outgoing internet traffic.
Avast’s firewall automatically configures itself, depending on how secure your network connection is. For instance, it’ll be more guarded if you’re connected to a public WiFi than your home or private connection.
I’m a fan of its “Stealth Mode,” which hides your device connected to a public network so that hackers can’t see you. It also provides ample customization, so you can block programs from connecting to the internet and block remote connections, ports, and protocols.

AVG’s firewall is a bit complicated to use for beginner s. However, I was happy to see that it offers plenty of customizability, especially in of setting up your traffic rules (basic rules, network rules, and application rules).

Overall, AVG’s firewall blocked me from opening potentially dangerous websites, malicious URLs in scam emails, and phishing attacks. However, it couldn’t detect some malicious links embedded in a handful of scam emails. Meanwhile, Avast’s firewall detected and blocked every threat I threw its way, providing security at par with McAfee’s highly configurable firewall.
Firewall Winner: Avast
7. Manager — Neither Antivirus Includes a Manager
Unfortunately, neither AVG nor Avast offers a manager on any of their plans. Avast used to offer it previously but doesn’t now. Instead, it provides its management service in another product called “Avast s.”
A manager is an essential feature because it keeps your online s safe. It also packs a auditor that checks for weak or reused s that can be easily hacked. It’s a great utility feature that lets you auto-fill complex web forms instead of filling them out yourself.
I highly recommend using Norton’s manager because it lets you save unlimited s and offers numerous utility features, such as two-factor authentication (2FA) and an automatic changer.
Manager Winner: None
8. Gaming Mode — Avast’s Game Mode Enhances Gaming Experience
I was happy to see both antiviruses equipped with a gaming mode. After digging deeper into it, I found Avast’s “Do not disturb” mode (formerly known as “Game Mode”) was better than AVG’s “Do not disturb” mode.
Avast’s “Do not disturb” mode is much more than a notification silencer. It just changed the name to include non-gamer audiences but includes all the essential features for avid gamers.
It suspended background applications and allocated system resources more efficiently, enabling me to play resource-heavy games like The Witcher 3 and Forza Horizon 5 in Ultra HD without any frame drops. It also silenced all non-critical notifications, such as Windows or program updates and browser-related notifications, which made my gaming experience more immersive.
AVG also features a “Do not disturb” mode, but it cannot allocate your system resources while gaming. It just does what the name suggests — mute your notifications so that you have an uninterrupted gaming experience.
Overall, Avast’s gaming mode is better because it has a dual function and enhances your system performance, whereas AVG’s gaming mode can only mute notifications.
Gaming Mode Winner: Avast
9. Optimization Tools — Avast’s Tune-up Facility Is Better but Still Not Worth Paying Extra for
Both AVG and Avast offer optimization tools only on their plan, but I wasn’t satisfied with either’s toolset. They didn’t improve my system performance significantly and provided only a handful of useful tools. I think it’s unwise to each contender’s plan to get optimization tools.
AVG’s PC TuneUp comes with its plan (AVG Ultimate) and is offered as a standalone feature. It includes a disk cleanup feature that clears your browser cache and removes junk and duplicate files from your PC.
I was also impressed to see it has a Startup Manager, but I was disappointed after using it. Disabling unneeded programs from automatically starting on system boot-up didn’t have a noticeable impact on my system performance. In contrast,
Avast’s optimization tools are a bit better but still not worth the extra money for the upgrade. I liked its disk cleaner, which cleaned up 5GB of junk files, cookies, and duplicate files on my PC.

Apart from that, Avast’s tune-up facility hosts a bloatware removal tool, which removes any potentially unwanted programs (PUPs) and any pre-installed software. It also has an “Automatic Updater” that keeps your Windows and apps updated. Those are great features but aren’t worth paying extra for. In fact, other antiviruses like Norton provide these basic features free with their mid-tier plan.
Overall, Avast’s optimization tools are slightly more efficacious than AVG’s. However, they’re only available on the plan, which is too pricey for the value these tune-up tools offer.
Optimization Tools Winner: Avast
10. Other Features — Avast Offers Security-Related Useful Extras
Both contenders offer extra features on their paid plans, but, after using them, I concluded that Avast’s additional features were more useful in of enhancing security.
Avast offers a Ransomware Shield that protects your vulnerable files and folders. It actively monitors any suspicious changes to your protected folders to prevent ransomware attacks. However, its detection capabilities aren’t as good as Bitdefender’s “Behavior Monitoring” tool.
I liked its “Online Security” browser extension, which is available on Chrome and Firefox. The extension prevents you from accidentally opening malicious websites and ing infected files.

Avast’s “Real Site” was my favorite feature — it prevents DNS hijacking, an attack that redirects you from a real site to its duplicate that wants to steal your credentials or credit card details. Real Site provides an encrypted connection from your browser to Avast’s DNS servers, preventing any likelihood of DNS hijacking. This may sound a bit complicated, but it’s straightforward to use — just toggle on Real Site, and that’s it.
I was happy with the extra features of both contenders, but Avast’s features offered me better online security than AVG’s. However, I was left with mixed feelings and would’ve liked to see more utility features like Norton’s cloud backup. Other Features Winner: Avast Avast is compatible with a greater range of OS versions. After thorough testing, I found that its apps (both desktop and mobile) were more intuitive and easy to use than AVG’s. AVG is compatible with Windows 7+, macOS 10.11+, Android 6.0+, and iOS 13+. Its desktop apps for Windows and Mac share a similar interface, but I found it challenging to locate features on both apps. For example, its SecureVPN and TuneUp features are hidden in the dropdown menu at the bottom. I found AVG’s mobile apps a bit confusing to navigate at first. I spent dozens of minutes trying to find the button on the dashboard and couldn’t find it. To , you have to tap the drop-down button on the top right and tap the “Already purchased?” button. The Android app packs more features than the iOS app. Its “Boost RAM” feature automatically closes background apps to increase system performance. The “Clean Junk” feature analyzes your device’s storage and optimizes it, and the “Scan WiFi” feature checks your WiFi connection for potential issues and threats. I would’ve liked to see its iOS app pack more features like some of the other iOS-focused antiviruses I’ve used before. Avast is compatible with Windows 7+, macOS 10.11+, Android 6.0+, and iOS 10+, so it’s compatible with a greater range of OS versions than AVG, namely iOS. I also found Avast’s desktop apps -friendly as compared to AVG’s. They have a clean interface with each feature clearly displayed on the dashboard.
Avast’s mobile apps are equally intuitive and -friendly as its desktop apps. They pack an anti-malware scanner, a WiFi scanner, remote control access, optimization tools, and an encrypted photo vault. The Android app additionally includes a “Boost RAM” feature that suspends unnecessary background activity to make your Android phone faster. Overall, Avast’s apps were significantly easier to use than AVG’s apps. Both its desktop and mobile apps make using the antivirus extremely easy on a range of devices, even for beginner s. Device Compatibility Winner: Avast I was surprised that neither antivirus provides a option other than live chat. I deem email and phone vital to any antivirus provider. Although they do offer phone , you’ll have to pay extra for that facility, which I think isn’t fair. Therefore, I can’t recommend either, as they fail to provide the most basic customer options. Avast’s live chat wasn’t easy to find. You must head to the Knowledge Base, select the category, and click the “ ” button. You’ll then have to provide your email address and other details. After doing all this, I still had to wait 5 minutes before an agent got back to me. However, I was satisfied with the agent’s responses.
AVG’s live chat is also difficult to find. You have to search for your question in the FAQ section and click the “ a live agent” button there. I had to wait for under a minute before an agent replied to me, and they answered my questions professionally. However, they were constantly trying to coax me into upgrading my plan. For that reason, I found Avast’s live chat better. Customer Service Winner: Avast After checking out each contender’s plans, I concluded that AVG’s plans pack more features for the same price than Avast does. However, I wasn’t satisfied with either antivirus, compared to the mid-tier plans of top competitors in the industry. AVG has 3 plans: Antivirus Free — The free plan provides basic protection and doesn’t offer real-time protection. However, I was happy to see it include extra security features, such as its file shield, web shield, email shield, and ransomware protection. While the free plan is good, you can find other free feature-rich antiviruses. Internet Security — The Internet Security plan includes all the features of the free plan, plus a firewall, manager, webcam protection, and DNS hijacking protection. On mobile apps, this plan includes some notable anti-theft features to protect your device if it’s ever stolen. This is AVG’s best value plan but lacks the features and protection offered by other contenders. Ultimate — AVG’s Ultimate Security plan offers all the features from the previous plans and adds optimization tools and VPN into the mix. Given the price point, it’s not worth the upgrade, especially when you’ll only get a sub-par VPN and a handful of optimization tools. Avast also offers 3 plans: Free Antivirus — The free plan includes a malware scanner, ransomware protection, and a WiFi inspector. While it doesn’t offer real-time protection, I was still happy with its performance on my tests. Security — Security packs all the features from the free plan, plus a firewall and ransomware shield. It also lets you use the antivirus on up to 10 devices — and that’s about it. Ultimate — If you want to the Ultimate plan, you’ll additionally get optimization tools, a manager, phishing protection, and a VPN. I don’t think either of these plans is worth the upgrade. Overall, AVG’s plan offers the best value, but if you’re a budget-conscious , I suggest you use its free plan. However, even with AVG’s paid plans, you won’t get the performance of a top-tier antivirus like Norton. Price Winner: AVG AVG and Avast offer a free plan in their antivirus product line-up; I found that AVG’s plan packed more features than Avast’s. AVG’s free plan provides basic protection and doesn’t include real-time protection. It packs a malware scanner and a handful of useful tools to enhance protection. Its “file shield” scans any new file you add to your PC. The “behavior shield” monitors any suspicious application behavior, such as an app trying to connect to the internet without your approval. It also offers ransomware protection, a web shield browser extension to protect you online, and a network inspector that checks if your internet connection is secure. I was impressed to see such features on the free plan, as many other antiviruses I’ve used have a barebones free plan. Avast’s free plan includes a malware scanner, ransomware protection, and a WiFi inspector. It offered me decent protection, but it doesn’t pack as many features as AVG’s free plan. Free Version: AVG Both contenders provide a 30-day money-back guarantee on all their paid plans. I tried out their refund policies first-hand and found claiming my refund with Avast easier. Avast makes it surprisingly easy to claim your full refund. I filled out a form on Avast’s website containing my name, mailing address, email address, order ID, and reason for refund. I got email confirmation within 5 minutes of submitting the form and received my money in 5 days. Claiming my refund with AVG was a bit more tedious. I initially submitted a refund request by filling out a form on its website, but I didn’t hear back nor got a confirmation email. After waiting for a response for 3 days, I hopped on to its live chat and initiated my refund request again. The agent processed my request, and I received an email confirmation right away and got my money back in 3 days. While AVG took less time to provide a refund, the entire process was not as seamless as Avast’s. I prefer a hassle-free and transparent refund process, even if it means getting a refund a few days later. Money-Back Guarantee Winner: Avast AVG outperformed Avast in real-time protection and detection scores but lagged in other areas, particularly ease of use. Overall, however, it was a close competition, with both contenders going neck in neck in most categories. Avast hosts a powerful firewall and features like “Real Site” that make it a solid antivirus. On the other hand, AVG’s malware scanner is better at detecting viruses and providing real-time protection. It also consumes fewer system resources than Avast, making it an obvious choice for regular s. However, its firewall doesn’t provide many advanced features. In summary, Avast won the most rounds, but I don’t recommend using either contender because they have been caught collecting and selling their s’ data to third-party advertising agencies. That reason alone should be enough to steer clear of them. Instead, I recommend going for a more transparent and reliable antivirus like Norton, which has given me excellent results repeatedly and is my go-to antivirus. Overall Winner: Avast
