It starts with a flicker. Maybe your battery, which usually lasts until dinner, hits 10% by noon. Or perhaps your phone starts opening Chrome tabs for "free gift cards" while it's sitting untouched on the nightstand. You’re panicking. You’re asking, how do i remove a virus from my phone before it drains your bank account or bricks the hardware. Honestly, the word "virus" is a bit of a misnomer in 2026. While traditional self-replicating viruses are rare on mobile operating systems like Android and iOS, malware is very, very real.
Adware, fleeceware, and sophisticated spyware like Pegasus have changed the game. If your phone is acting possessed, you aren't imagining it. But here’s the good news: unless you’re a high-level political target or you've been downloading "free" cracked versions of Minecraft from sketchy forums, you can probably fix this in about ten minutes.
Identifying the Red Flags
Before we start deleting things, we need to be sure you actually have an infection. Your phone might just be old. Or the latest OS update might have a bug. However, if you see high data usage that you can’t explain, it’s a massive red flag. Malware often pings "command and control" servers in the background. It’s uploading your contacts or downloading more junk.

Look for apps you don't remember installing. Check your settings. If there's an app with a generic name like "System Update" or "Flash Player" (which hasn't existed for years), that’s your culprit. Overheating is another big one. If your phone feels like a hot potato while it’s just sitting in your pocket, something is burning CPU cycles. It’s usually a hidden miner or an aggressive ad-tracker.
How Do I Remove a Virus From My Phone on Android?
Android is the "Wild West" of mobile security because it allows sideloading. If you've ever checked that box that says "Install from Unknown Sources," you basically opened the front door and invited the vampires in.
First step? Safe Mode. This is non-negotiable. Safe mode prevents third-party apps from running. On most modern Androids, you hold the power button, then long-press the "Power Off" icon on the screen until "Reboot to Safe Mode" pops up. Tap it. Your phone will restart, and you’ll see "Safe Mode" written in the corner. If the weird pop-ups stop and the phone stops lagging, you’ve confirmed the problem is a third-party app.
Go to Settings. Then Apps. Look for anything suspicious. There are some nasty pieces of malware that use a blank icon or no name at all. If you see a line in your app list that has a size (like 15MB) but no name or icon, delete it immediately. Just tap it and hit uninstall.
Sometimes the "Uninstall" button is greyed out. This is where people get stuck. It means the malware has granted itself "Device Administrator" status. You have to revoke that. Go to Settings > Security > Device Admin Apps (the path might vary slightly depending on if you're on a Samsung or a Pixel). Toggle off the permission for the suspicious app. Now, go back to the Apps menu. The uninstall button should be clickable.
The iPhone Myth: Can Apple Devices Get Viruses?
Apple fans love to brag that iPhones don't get viruses. Technically, they’re mostly right because of "sandboxing." Every app lives in its own little plastic bubble and can't see what other apps are doing. But iPhones get "compromised" in other ways.
Most "iPhone viruses" are actually just malicious calendar invites or rogue browser profiles. Have you ever seen a pop-up saying "Your iPhone has 13 viruses, click here to clean"? That’s a scam. If you clicked it, it might have installed a "Configuration Profile."
Go to Settings > General > VPN & Device Management. If you see anything there that you didn't specifically put there for work or a school VPN, delete it. That profile is likely rerouting your internet traffic through a hacker’s server. Also, check your Calendar app. If it’s full of "Your phone is at risk" entries, you just need to go to Settings > Calendar > Accounts and delete the "Subscribed Calendar" that’s causing the spam.
Clearing the Browser Cache
Often, the "virus" is just a persistent script stuck in your mobile browser. It’s annoying. It’s loud. But it’s not deep in your system.
On Chrome (Android), tap the three dots > Settings > Privacy and Security > Clear browsing data. Make sure "Cached images and files" and "Cookies" are checked. On Safari (iPhone), go to Settings > Safari > Clear History and Website Data. This kills the script that keeps triggering those fake "System Warning" pop-ups. It’s a simple fix that solves about 80% of the "help, my phone is hacked" queries I see.
When to Use an Antivirus App
Do you actually need a dedicated antivirus? In 2026, the answer is "maybe." If you're on a Pixel with Google Play Protect enabled, you're already being scanned constantly. However, if you've been hit once, you might want a second opinion.

Reliable names like Bitdefender, Malwarebytes, or Avast have mobile versions. They are great for a one-time scan. Install one, run the "Full Scan," and then—this is the important part—uninstall it if you don't want to pay for the premium version. Having three different "security" apps running at once will actually slow your phone down more than a minor piece of adware would. They fight over resources. It’s a mess.
The Nuclear Option: Factory Reset
If you’ve tried everything and the phone is still acting crazy—or if you suspect a keylogger is tracking your banking passwords—you have to wipe it. It sucks. I know. But it’s the only way to be 100% sure.
Back up your photos to Google Photos or iCloud first. Do not do a full system backup and then restore it. If you back up the "system state," you might just be backing up the malware and re-installing it ten minutes later. Back up only your essential data—contacts, photos, and documents.
Go to Settings > System > Reset options > Erase all data (factory reset). On iPhone, it’s Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Once it’s done, your phone will be as clean as the day you took it out of the box. Log in, download your apps manually from the official store, and stay away from the shady parts of the web.
Why This Keeps Happening
Prevention is better than a frantic Google search at 2:00 AM. Most people get infected because of "Malvertising." You’re on a site trying to stream a movie for free, you click "Play," and instead of the movie, a small file downloads.
- Avoid Sideloading: Unless you are a developer, don't install APK files from websites. Use the Play Store or the Galaxy Store.
- Check Permissions: If a calculator app asks for permission to access your microphone and contacts, say no. It doesn't need them.
- Update Your Software: Those "Security Patch" notifications are boring. I get it. But they often contain fixes for "Zero-Day" vulnerabilities that hackers are actively using to bypass phone security.
Actionable Next Steps
To wrap this up and get your phone back to normal, follow this checklist immediately:
- Enter Safe Mode: This stops the "attacker" from running while you work.
- Check Admin Apps: Strip away any weird permissions in your security settings.
- Audit Your App List: Sort by "Recently Used" or "Last Used." If an app you haven't opened in months shows it was used today, kill it.
- Clear Browser Data: Wipe the cache in Chrome or Safari to stop the pop-up loops.
- Change Your Passwords: If you think you had a virus, assume your passwords were seen. Start with your primary email and your banking apps. Turn on Two-Factor Authentication (2FA) while you’re at it—but use an authenticator app like Authy or Google Authenticator rather than SMS, which can be intercepted via SIM swapping.
Keep your OS updated and stop clicking on "You've won a $1,000 Amazon Gift Card" banners. Your phone—and your sanity—will thank you.
