Can Chromebooks Get Viruses? How to Protect Your Device

Chromebooks are designed with robust security features, including sandboxing, Verified Boot, automatic updates, data encryption, and Recovery Mode, which collectively reduce the risk of malware infections. However, they are still vulnerable to threats such as malicious Chrome extensions, scam Android apps from third-party stores, phishing attacks, and risks associated with using Developer Mode and cloud storage. Users can identify potential malware through signs like slow performance, unexpected pop-ups, and unusual battery drain. To remove malware, users should eliminate suspicious extensions, uninstall dubious apps, run antivirus scans, enable Google Play Protect, or perform a Powerwash to reset the device. To protect their Chromebooks, users should avoid Developer Mode, check app permissions, use two-factor authentication, verify website URLs, and use a VPN on public Wi-Fi.

Fake virus alerts are invading mobile games

Cybercriminals sometimes manage to buy advertising space and use it to defraud gamers. The iCloud storage scam is a well-known scam that claims you need to expand your storage or all your files will be deleted. Scammers also use fake warnings to trick users into clicking links or downloading harmful software. Fleeceware apps lure users in with short free trials that quickly convert into hidden subscription fees. The best response to these messages is to ignore them and use an up-to-date anti-malware solution on your devices.

Over 50 Android Apps Found Spreading MagicAd Trojan via Official Stores

A trojan named Android.MagicAd.1 has been identified as a significant threat to Android users, capable of delivering persistent background advertisements by circumventing built-in defenses. Detected in 2025, it has spread through over 50 infected games and utility applications, infiltrating both dubious download sites and official app stores like the Samsung Galaxy Store and Xiaomi’s GetApps. The malware employs a strategy of rotating applications to evade detection, remaining active on user devices after download. It uses hidden, encrypted components within native code libraries and conducts environment checks to avoid monitoring before launching its payload. Android.MagicAd.1 bypasses Android's restrictions by targeting trusted system applications, utilizing methods that vary by device manufacturer. For example, it uses a delayed system command on Xiaomi and Amazon devices, exploits Android Binder on Vivo devices, and employs a universal fallback method for other brands to gain priority for displaying ads. All identified malicious applications have been removed from official stores, but the campaign highlights the vulnerability of security software.

What the Tech? What to ask yourself before downloading an anti-virus app

Most individuals do not require antivirus apps on their smartphones, as the primary threats are scams rather than traditional viruses. iPhones use app isolation, making conventional antivirus scans ineffective; threats include phishing texts and fraudulent websites. Android phones allow sideloading, increasing the risk of malware from unofficial sources. The main dangers are deceptive tactics like phishing, scam calls, and social engineering. To enhance security, users should keep their operating systems updated, use strong passwords, enable two-factor authentication, avoid suspicious links, and refrain from installing apps from unknown sources. Antivirus apps may be beneficial for users who frequently click unverified links, download files from unfamiliar sites, or engage in Android sideloading. Reputable security apps focus on scam detection and account safety rather than traditional virus scanning.

Do you need antivirus on your phone?

Mobile security discussions often question the necessity of antivirus programs for smartphones. While traditionally seen as essential, the need for antivirus software is being reevaluated, especially for advanced smartphones. Apple's iPhone has stringent security measures that prevent traditional antivirus scanning, with scams being the primary threat rather than viruses. In contrast, Android devices allow sideloading, increasing the risk of malware, despite Google monitoring the Play Store. For users primarily downloading from official stores, antivirus applications may not be necessary. Instead, users should focus on keeping devices updated, using strong passwords, and enabling two-factor authentication to enhance security.

Beware of Activating Them: 5 Android App Permissions That Pose a Threat to Your Data

Android applications often request various permissions upon installation, including access to the camera, microphone, contacts, messages, and accessibility features. Users frequently accept these requests without hesitation, which can compromise their device's privacy and security. Certain permissions, if granted to malicious apps, can enable monitoring of user activity, audio recording, location tracking, or unauthorized app installations. Five Android app permissions that require careful consideration before granting include: 1. Accessibility Services: Can allow untrusted apps to monitor screen content, read messages, track keystrokes, and perform actions on behalf of the user. 2. Display Over Other Apps: Allows apps to overlay content on other apps, which can be exploited by malicious apps to create deceptive interfaces. 3. Install Unknown Apps: Permits apps to install software from outside the Google Play Store, increasing the risk of malware. 4. Usage Data Access: Enables apps to monitor usage patterns, which can be used for targeted advertising or sold to data brokers. 5. Access to Contacts and Messages (SMS): Sensitive information can be intercepted by malicious apps, posing risks to account security. It is crucial to grant permissions that align with an app's intended function and to be cautious of unnecessary access.

5 Android App Permissions You Should Never Allow

Users should be cautious when granting permissions to applications on Android devices, as extensive access can lead to security vulnerabilities. Apps with accessibility permissions can perform actions like hacking passwords and altering device settings without user consent. Overlay permissions allow apps to display content over others, which can be exploited by malicious apps to trick users into providing sensitive information. Installing apps from unknown sources poses risks to device security and privacy. Usage data access enables apps to monitor user activity, which can be sold to advertisers. Granting access to contacts and SMS can lead to privacy concerns, as this information can be exploited by malicious entities. Users are advised to regularly review and manage app permissions to mitigate potential threats.
