Maybe you've started noticing that your phone heats up for no reason, that it turns off by itself, that strange ads appear even when you're not using any apps. Sound familiar?
In most cases, these problems have a clear origin: viruses, malware or hidden programs that are installed without your authorization.
Many of them arrive bundled with unknown apps or dangerous links that seem harmless.
This article will guide you step-by-step through detecting these viruses, understanding why such annoying ads appear, and, most importantly, how to remove them quickly and cheaply.
And best of all, we're going to recommend three reliable and free apps that clean your phone, remove viruses, and block ads once and for all.
What kind of viruses can infect your cell phone?
The malware that steals your peace (and your data)
When we talk about "viruses," we're referring to any program that enters your phone without permission and causes damage. These are some common types:
- Adware: floods you with invasive ads.
- Spyware: spy on your messages, calls and even your photos.
- Ransomware: blocks your cell phone and asks for money to release it.
- Trojans: They disguise themselves as normal apps but operate secretly.
These viruses often arise out of curiosity: you downloaded a game that wasn't on the Play Store, or you clicked on a "you won a prize" message. Sounds common, right?
The problem is that once they're inside, it's hard to notice them. You can't always see them.
But you do feel them: a slow cell phone, a dying battery, strange messages… all of these could be signs of infection.

How do you know if you have a virus?
Here is a simple list of symptoms:
- Your cell phone is slower than normal
- Pop-ups open by themselves
- You hear sounds even if you don't have any apps open.
- Icons or apps appear that you don't remember installing
- Your mobile data is consumed faster
- Your battery drains for no reason
If you have two or more of these symptoms, it's time to take action.
What about the ads? Why don't they go away?
Normal ads vs. dangerous ads
It's true: many free apps display ads to make money. But that's normal and under control. The problem is when the ads:
- They appear even if you are not using any app
- They jump on the home screen
- They contain inappropriate content (gambling, adult, etc.)
- They redirect you to fake pages or pages that ask for your data
These ads are the result of adware, which is not only annoying, it can also be the beginning of something worse.
Why don't these ads disappear?
Because the virus "hides" in the system. Even if you delete the app that brought it, the adware is already active and needs a deep clean to get rid of it. This is where specialized apps come in handy.
What can you do to remove viruses and ads?
Step 1: Don't install any app
This seems obvious, but sometimes out of haste or curiosity we fall into the trap:
- Avoid downloading apps from outside the Play Store
- Always check the reviews and ratings
- If an app asks for access to everything (camera, contacts, location), be suspicious!
Step 2: Use a reliable antivirus
You don't need to pay for one. There are free options that do an excellent job: they detect threats, clean your system, block ads, and even protect your personal files.
The important thing is to choose a reliable app with millions of downloads.
Step 3: Perform a full scan
After installing your antivirus, run a full scan. This may take a few minutes, but it's worth it. It will detect dangerous apps, hidden files, and processes that could be affecting your phone.
Then, set the automatic scan to repeat every day or every week.
Step 4: Eliminate what you don't recognize
Are there apps you don't remember installing? Delete them. Especially if they have strange names or suspicious icons.
If you can't uninstall them, your antivirus can often force it for you.
Step 5: Block the entry of new viruses
Once clean, activate functions such as:
- Real-time protection
- Blocking dangerous pages
- Filter unsafe Wi-Fi networks
All of this is done by the apps we're going to recommend below.

Is it necessary to have antivirus on Android?
This is a common question. Technically, Android has certain protections, but are not enough Yeah:
- Download apps from external sites
- You use public Wi-Fi without protection
- You don't update the operating system

What else can you do to keep your phone clean?

True Stories: How an Antivirus Changed the Experience
Carlos, 27 years old, Mexico City:
“I installed a game from a link a friend sent me on WhatsApp. Everything was fine at first, but the next day ads started appearing every time I unlocked my phone. I tried everything, but they wouldn't go away. Then I downloaded AVG, and it found three suspicious files, which I deleted. Goodbye ads!”
Lucia, mother of two children:
“My daughter's phone was full of weird apps. We'd delete one and two more would appear. With Norton 360, we were able to do a deep clean. Since then, there are no more weird ads or strange messages.”
