How to Scan for Malware on Your Galaxy S24/S25
I recently helped a family member troubleshoot a Galaxy phone that suddenly started showing unusual pop-ups and battery drain. The device wasn't infected with a major virus, but a suspicious app was running in the background and causing problems. That experience reminded me how many Samsung Galaxy users aren't aware that their phones already include powerful built-in malware protection tools. If you own a Galaxy S24, Galaxy S24 Ultra, Galaxy S25, or Galaxy S25 Ultra, knowing how to properly scan for malware is one of the easiest ways to keep your device secure.
Modern Samsung phones include multiple security layers such as Device Protection, App Protection, Google Play Protect, and Auto Blocker. However, many users are unsure which tools they need, where to find them in One UI, and whether they should install a third-party antivirus app. This guide covers everything you need to know.
Quick Answer
To scan your Galaxy S24 or Galaxy S25 for malware, open Settings → Battery and Device Care → Device Protection → Scan Phone. For maximum protection, also enable Google Play Protect and Samsung Auto Blocker. Most Samsung Galaxy users do not need a separate antivirus app if they keep these built-in protections enabled and install apps only from trusted sources.
Why This Matters
Malware on a smartphone can do much more than display annoying advertisements. It can affect privacy, battery life, performance, data security, and overall device reliability.
Potential risks include:
- Unauthorized access to personal information
- Increased battery drain
- Background data usage
- Slower device performance
- Financial fraud attempts
- Account compromise
- Persistent pop-ups and unwanted notifications
Regular malware scans help identify suspicious behavior before it becomes a larger problem.
Does the Galaxy S24 and Galaxy S25 Have Built-In Malware Protection?
Yes. Samsung Galaxy phones include several built-in security systems designed to detect, prevent, and reduce malware threats.
| Security Feature | Purpose |
|---|---|
| Device Protection | Scans the device for malware and threats |
| App Protection | Checks installed apps for harmful behavior |
| Google Play Protect | Continuously scans apps from Google Play |
| Auto Blocker | Prevents unauthorized app installations and attacks |
This combination provides multiple layers of protection without requiring additional security software for most users.
Signs Your Galaxy S24 or S25 May Have Malware
Before running a scan, look for common warning signs.
Unexpected Battery Drain
One of the most common complaints among Samsung users is sudden battery drain caused by suspicious background processes.
Excessive Device Heat
If your Galaxy phone becomes unusually warm during normal use, malware may be consuming system resources.
Random Pop-Ups
Frequent advertisements appearing outside your browser can indicate adware.
Slow Performance
Apps opening slowly, lagging animations, or delayed touch response may be related to malicious background activity.
Unknown Apps
If you notice apps you don't remember installing, investigate immediately.
High Data Usage
Malware sometimes communicates with remote servers and can significantly increase mobile data consumption.
How to Scan Your Galaxy S24 or S25 for Malware Using Device Protection
The quickest way to check your Samsung phone for malware is through Device Protection.
Step 1: Open Settings
Launch the Settings app.
Step 2: Navigate to Device Protection
Go to:
Settings → Battery and Device Care → Device Protection
Step 3: Run a Malware Scan
Tap:
Scan Phone
The system will examine apps and files for potential threats.
Step 4: Review Results
If suspicious items are detected, follow Samsung's recommendations to remove or disable them.
This process usually takes only a few minutes.
How to Enable App Protection on Galaxy S24 and S25
Many users confuse App Protection with Device Protection. While Device Protection performs manual scans, App Protection continuously helps identify harmful applications.
Depending on your One UI version, App Protection may appear under Security and Privacy settings.
Check:
Settings → Security and Privacy → App Protection
If available on your device, ensure the feature is enabled.
This provides another layer of malware detection beyond manual scans.
How to Use Google Play Protect on Samsung Galaxy Phones
Google Play Protect is one of the most important security features on Android.
It automatically scans apps before installation and continues checking them after installation.
Enable Google Play Protect
Open:
Google Play Store → Profile Icon → Play Protect → Settings
Enable:
- Scan Apps With Play Protect
- Improve Harmful App Detection
This helps detect threats even after an app has already been installed.
What Is Auto Blocker and Should You Enable It?
Yes. Most Galaxy S24 and Galaxy S25 users should enable Auto Blocker.
Auto Blocker has become one of Samsung's most important security features and is frequently discussed in Samsung communities.
Its primary purpose is preventing malware before it reaches your phone.
What Auto Blocker Does
- Blocks unauthorized app installations
- Restricts risky USB commands
- Reduces exposure to malicious software
- Adds protection against common attack methods
How to Enable Auto Blocker
Open:
Settings → Security and Privacy → Auto Blocker
Turn the feature on.
Many security-focused Samsung users now consider Auto Blocker one of the most valuable security settings available.
Device Protection vs App Protection vs Play Protect vs Auto Blocker
One of the biggest points of confusion among Galaxy users is understanding the difference between Samsung's various security tools.
| Feature | Main Function | Recommended |
|---|---|---|
| Device Protection | Manual malware scanning | Yes |
| App Protection | Application threat detection | Yes |
| Google Play Protect | Continuous app monitoring | Yes |
| Auto Blocker | Prevents malicious installations | Yes |
The strongest protection comes from enabling all four.
One UI 6, One UI 6.1, and One UI 7 Security Differences
Many Galaxy users report difficulty finding malware protection settings after major One UI updates.
One UI 6 and One UI 6.1
- Auto Blocker introduced
- Security options spread across multiple menus
- Many users unaware Auto Blocker exists
One UI 6.1.1
- Security menu adjustments caused confusion
- Some users reported difficulty locating App Protection settings
One UI 7

- Settings locations may vary slightly by device and carrier
If you cannot find a setting mentioned in this guide, use the search bar within Settings and search for the feature by name.
Common User Complaints About Samsung Malware Protection
Research across Samsung communities and Reddit discussions reveals several recurring concerns.
"I Can't Find Device Protection"
This is especially common after One UI updates. Samsung occasionally reorganizes menus, making security features harder to locate.
"Do I Really Need Antivirus Software?"
Many users wonder whether Samsung's built-in protections are enough.
For most people who install apps only from trusted sources, Device Protection, Play Protect, and Auto Blocker provide strong protection.
"Does Security Scanning Hurt Battery Life?"
Some users report concerns about background security scans affecting battery life.
In real-world usage, the impact is generally minimal compared to the security benefits.
"Auto Blocker Is Preventing Something I Want To Install"
This is one of the most common complaints.
Auto Blocker intentionally restricts potentially risky installations to improve security.
Do You Need a Third-Party Antivirus App on Galaxy S24 or S25?
In most situations, no.
If you:
- Use Google Play Store apps
- Keep One UI updated
- Enable Auto Blocker
- Use Device Protection
- Keep Play Protect active
you already have multiple layers of protection.
Third-party antivirus software may be useful for users who frequently sideload apps, install software from unknown sources, or manage sensitive business information.
How to Remove Malware From a Samsung Galaxy Phone
If a malware scan identifies a threat, follow these steps.
Remove Suspicious Apps
Go to:
Settings → Apps
Uninstall any unfamiliar applications.
Run Another Scan
Use Device Protection to verify removal.
Clear Browser Data
Many fake virus warnings originate from browser notifications.
Open your browser settings and clear site permissions and browsing data.
