What is Malware?

Malware, short for malicious software, is any program or file designed to harm your computer, phone, network, or server.

It includes viruses, worms, ransomware, Trojan horses, and spyware. There are some Windows ransomware protections that you can use to protect your device.

These programs can steal, encrypt, or delete your data, mess with your system’s core functions, or track what you’re doing on your device.

How To Know if You Have Malware

Watch out for unusual behaviour on your phone, tablet, or computer. You might have malware if your device suddenly:

It slows down, crashes, or shows a bunch of error messages
Won’t shut down or restart properly
Blocks you from uninstalling apps or software
Bombards you with pop-ups or inappropriate ads
Shows ads on websites where you don’t normally see them, like government pages
Displays unexpected toolbars or new icons on your desktop or browser
Changes your default search engine, opens new tabs, or loads websites you didn’t click on
Changes your homepage or settings without your permission
Sends out emails you didn’t write
Drains your battery way faster than usual

How do Malware Infections Happen?

Hackers use many tricks to get malware onto your device or network. Here are the main ways:

#1. USB and External Drives

Malware can sneak onto your device when you connect a USB or external hard drive. Sometimes, it installs automatically when the infected drive is plugged in.

#2. Infected Websites

Malicious websites can download malware onto your device without you even knowing. This often happens through collaboration tools or “drive-by downloads” that run in the background while you’re on the site.

#3. Phishing Attacks

Phishing emails look legitimate but hide malware in their links or attachments. Once clicked, the malware gets on your system, often giving hackers access to your data and even remote control over your device.

#4. Hiding and Evasion Techniques

Some malware is built to hide from security software and trick users. It can change its code regularly, making it hard for detection tools to spot.

Others delay running until they’ve avoided security scans, and some hide entirely in your system’s RAM, making them even harder to detect.

#5. Malicious App Downloads

Downloading sketchy apps is one of the most common ways to get malware. While official app stores are generally safer, they’re not foolproof, and some bad apps still sneak through.

Apps from untrusted sources are even more likely to carry malware, so it’s essential to stay alert.

In short, malware can mess up your device in many ways. Knowing the warning signs and how they spread can help you stay one step ahead.

How To Avoid Malware When Downloading Apps

Scammers try to fool people into clicking on links that secretly download viruses, spyware, and other unwanted software, often hidden in free downloads. You can also check here for the top 10 most dangerous viruses in computers ever created.

Here’s how you can avoid getting malware when downloading apps:

#1. Pay Attention When Installing Software

Always read every screen when installing new software. If you don’t recognize a program or it tries to sneak in extra software, say no or exit the installation.

#2. Download From Official Sources

Stick to downloading well-known software directly from trusted websites. Sites offering many free popular apps, like browsers or PDF readers, are more likely to bundle malware.

#3. Watch for Security Warnings

Most browsers have built-in security features that warn you before you visit a sketchy website or download a bad file. Make sure to pay attention to these warnings.

#4. Type Trusted URLs Yourself

Instead of clicking links in emails or text messages, type the URL of trusted websites directly into your browser. Scammers often use phishing emails to trick you into clicking on harmful links or attachments.

#5. Avoid Clicking Pop-Ups or Performance Ads

If you see pop-ups or ads claiming your computer has issues or needs better performance, don’t click them unless you know they’re from a reliable source. Scammers use these to sneak in malware.

#6. Scan USBs and Other Devices Before Using

Always scan USB drives or other external devices before using them, especially if you’ve plugged them into public computers or high-traffic places like photo printing stations. They can easily pick up malware.

By staying cautious and following these steps, you can keep your device safe from malware.

5 Ways to Stay Safe When Downloading Apps

Taking simple precautions can go a long way in keeping your sensitive data safe from hackers who use malware to steal information from your mobile devices. Here are five tips to help you stay secure when downloading apps:

#1. Download Apps from Trusted Sources

Stick to official app stores like the Apple Store, Google Play, and Samsung Galaxy Store, which have millions of apps across various categories. You’re unlikely to run out of options.

However, you might find apps on other websites or third-party stores. While that doesn’t always mean it’s a scam, hackers often use these platforms to spread malware.

Some of these stores lack proper security checks, and cybercriminals even create fake websites to trick you into downloading harmful apps.

Even trusted stores aren’t foolproof—malicious apps sometimes slip through, and it might take days, months, or even years before they’re caught and removed.

At that time, thousands or even millions of devices could get infected. So, always be careful!

#2. Watch the App Permissions

Apps usually ask for permissions like access to your camera, photos, contacts, or location, depending on what they do. Common permissions include:

Contacts
Photos
Location
Calendar
Browsing history
Microphone
Camera
Storage
Calls

Some apps need these permissions to work properly, but others might misuse them. For example, a shady app could request access to your texts or emails and steal important data. It could also ask for your location and track you without your knowledge.

Always double-check the permissions an app asks for. Ensure the app is trustworthy, and think twice before allowing access to things like your camera, microphone, browsing history, and contacts. These permissions carry the most risk, so stay alert!

Following these simple steps, you can better protect yourself and your devices from malware and keep your personal data safe when downloading.

#3. Check the User Reviews

Before downloading an app, it’s always smart to check the reviews, like buying a new pair of shoes or picking an antivirus program.

Most app stores, like Google Play or the Apple Store, let users leave reviews, sharing their good or bad experiences. These reviews can help you decide if an app is safe or sketchy, so make it a habit to read them before hitting “install.”

If you see mostly negative reviews, it could mean the app has issues like bad design, poor data management, battery drain, or questionable permissions. These red flags could be signs of a dangerous or malicious app.

If the app doesn’t have many reviews in the store, try searching for more info on the web. But remember, even apps with primarily positive reviews aren’t always safe. Some developers are good at hiding shady activities, and it might take experts a while to catch on.

#4. Pay Attention to Download Numbers

Apps like Instagram, TikTok, and YouTube have massive download numbers, sometimes billions. But not all apps hit those numbers, and that’s okay. Some useful apps may have fewer downloads simply because they’re new or not widely known.

However, if an app has very few downloads and reviews, it’s harder to know if it’s safe or not. If you’re interested in such an app, it might be better to wait a few weeks until more people have downloaded and reviewed it.

#5. Watch Your Device’s Performance

After downloading an app, monitor its behavior. If you notice your phone suddenly acting weird—like the battery draining super fast, frequent crashes, or the device freezing—it could be a sign that the app brought in malware, like spyware, which runs in the background and eats up your battery.

Not all apps that use a lot of power are bad. Some legit apps need to run in the background and use more battery. But if your phone starts having issues after downloading a specific app, that app might be the problem.

By following these steps, you can avoid downloading harmful apps with malware and keep your device running smoothly.

How To Stay Safe When Downloading Apps

#1. Set Up App Whitelist/Blocklist

Create a whitelist for apps you trust and need so only approved apps can be installed on your device. At the same time, make a blacklist of unnecessary or suspicious apps to block them and reduce any potential risk.

#2. Keep Your Apps Updated

Always update your device and apps to the latest versions. These updates often include security fixes, bug patches, and performance improvements, which help protect your device from vulnerabilities.

#3. Use Antivirus and Security Software

Install a reliable antivirus or security app for real-time protection against malware, phishing, and other threats. This will boost your overall security and help keep your device safe.

#4. Enable App Sandboxing

Turn on app sandboxing on your device to limit apps’ access to sensitive data or features. This way, even if an app tries something suspicious, it can’t reach beyond its intended scope.

#5. Check Reviews and Permissions

Always read app reviews and ratings before downloading. Look at both positive and negative feedback to fully understand the app’s safety and reliability. Also, double-check the permissions it asks for to avoid giving access to anything unnecessary.

#6. Use App Testing Tools

Before installing an app, you can use app testing tools to check its security and performance. These tools can help you spot any potential issues, allowing you to make a more informed decision.

Bonus Tip: Turn On Google Play Protect (for Android)

If you’re an Android user, activate Google Play Protect. This built-in feature regularly scans apps from the Google Play Store and protects against harmful apps. You can also check if your phone has been tapped.

By following these tips, you can download apps more confidently and keep your device secure.
