Bitdefender Antivirus Free uses the same scanning engine as its paid version (Bitdefender Mobile Security) and stands out for its outstanding protection rating from AV-Test.

It would be nice if it was possible to use Bitdefender Antivirus Free on more than one device, but this limitation is common with free antivirus tools.

Avira Free Antivirus has garnered a lot of impressive reviews from Android users. This isn’t too surprising when you consider its excellent lab test results. Its real-time protection works around the clock to protect your device from new threats. It has one of the easiest-to-use Android apps of any free antivirus with its many different features clearly laid out and explained.
Most free antivirus offerings for Android protect you from viruses and that’s the extent of it, but Avira Free Antivirus also has web protection (blocks ads, trackers, and malicious web pages), a password manager, and a VPN. The VPN only includes 100 MB of data a day, which won’t be anywhere near enough for many users. Still, it’s better than nothing, particularly if you have moments when you need to connect to unsecured public wifi.
Avira Free Antivirus has apps for all of the following: Android, Windows, Mac, and iOS.
Pros:
- Lots of extras such as a password manager
- Excellent independent testing scores
- App interface is very easy to use

AVG Antivirus Free positions itself as an all-in-one security app for your Android device, focusing on security, privacy, and performance. It protects your device not only from viruses, but other types of malware. This includes ransomware, which is not something that many free antivirus programs for Android protect against.
There’s an impressive number of features for a free antivirus. For example, ad and tracker blocking and a VPN (although data is limited to a measly 500 MB a month). AVG Antivirus Free’s Safe Shopping feature helps you identify coupons and deals. It is lacking in the way of support, though this can be said of the vast majority of free antivirus tools.

- Plenty of extra security features
- Beginner-friendly app interface

Free antivirus for Android: FAQs
What are some key features to look for in free antivirus software?
Of course, a free antivirus for Android (or indeed any other operating system) must provide effective malware detection. Real-time protection is important because it can proactively prevent malware from infecting your device. When testing antivirus tools, we also look for those that offer regular updates to protect you from the newest threats. More specific features to look out for include web and phishing protection and privacy tools such as a VPN.
How does free antivirus software differ from paid versions?
Free antivirus software tends to offer basic protection. Generally, you can expect real-time protection, particularly with the best free antivirus tools for Android. Although the free antivirus programs we’ve covered include numerous extras, some tend to be more limited than paid versions. For example, a free version’s VPN will have a limited data allowance.
Other features, such as a firewall or ransomware protection, are much more common in paid plans. Customer support with free antivirus software tends to be limited to FAQs and community forums while a paid antivirus is likely to offer live chat, email, and maybe even phone support.
Is free antivirus software safe to use?
Free antivirus software can be safe to use. However, it’s important to choose a reputable antivirus provider for your Android device. Although free antivirus programs tend to offer basic protection, it’s nonetheless effective and more than sufficient for most people’s needs. Of course, there are some limitations and fewer advanced features but, provided your antivirus for Android has real-time protection to monitor for threats, your device should be safe.
Will an antivirus slow down my device?
Although an antivirus can slow your device, the extent of this depends on the antivirus program you’re using and your smartphone or tablet’s specifications. Older or lower-end devices may have more noticeable slowdowns for example. Full system scans as well as real-time protection tend to consume significantly more resources. Choosing one of the best free antivirus tools means you’ll have a lightweight and efficient antivirus which reduces the impact on your device’s performance.
What’s the difference between free Android antivirus and paid versions?
Free Android antiviruses offer basic malware protection and manual scans, often with ads and limited support. They typically cover a single device and may have delayed updates. Paid Android antivirus, on the other hand, provides a more comprehensive package. They include advanced features like real-time protection, anti-theft measures, and Wi-Fi security. Paid options are usually ad-free and offer priority customer support.
The premium versions also tend to receive faster and more frequent updates. They often come with additional tools such as VPNs, password managers, or performance optimization features.
Paid antiviruses generally allow multi-device coverage and offer more advanced scan scheduling options. While free Android antiviruses provide essential protection, paid versions offer a more robust and user-friendly security experience.
