Free Antivirus for Android: Best Apps to Protect Your Smartphone

Smartphones are integral to daily life, storing emails, banking apps, and social media. The Android operating system is vulnerable to threats like viruses and ransomware. Free Android antivirus tools offer basic protection but have limitations compared to paid versions. Free antivirus solutions focus on malware scanning and threat detection. Bitdefender Mobile Security (Free Version) provides lightweight background operation, real-time scanning, and web protection but lacks anti-theft and VPN features. Norton Mobile Security (Free Tier) offers essential malware scanning, with advanced features available in premium subscriptions. Avast Mobile Security (Free) includes virus scanning, malware protection, and anti-theft tools, allowing users to lock apps and protect against malicious websites. AVG AntiVirus (Free) offers virus, malware, and spyware scanning, real-time updates, and a "Photo Vault" for securing images. Kaspersky Mobile Security (Free) provides basic virus protection and ranks high in malware detection, with additional features available in paid plans. Free antivirus tools detect malware and monitor real-time system activity, alerting users to phishing sites. They may scan files transferred via USB or Bluetooth and offer limited VPN services. Limitations of free antivirus include the absence of advanced features like unlimited VPN, application locking, and anti-theft capabilities. Many rely on ads for revenue, which can disrupt user experience. Choosing the right antivirus depends on usage habits and security concerns. Running multiple antivirus apps can cause conflicts and hinder performance. Upgrading to premium versions may be necessary for comprehensive protection, especially for sensitive tasks. User behavior is crucial for security; regularly updating the OS and applications, using strong passwords, and considering two-factor authentication can enhance protection. Free antivirus apps offer core threat protection but lack advanced features. Most are lightweight, with minimal impact on performance. Regular scans are recommended, and reputable sources should be used for downloads. Free antivirus apps can warn about phishing attempts but cannot eliminate the risk entirely. A built-in VPN is not essential for basic protection but is advisable for public Wi-Fi use.

Hackers Are Using Fake Invitations to Take Over Your PC

Cybercriminals are sending counterfeit email invitations that, when clicked, install a backdoor on the victim's computer, allowing hackers full control. The scam often involves downloading a file named “invites.msi,” which is a Windows Installer package. This file can install ScreenConnect, a legitimate remote support tool that can be exploited by attackers to monitor screens, access files, and deploy additional malware. Many security engines fail to flag this software as malicious, making it difficult to detect. If someone suspects they have fallen victim to this scam, they should disconnect from the internet, check for and uninstall any remote management software, run a comprehensive antivirus scan, change passwords for critical accounts, enable two-factor authentication, inform their IT department if applicable, and consider performing a full Windows reset. The scam originated from a compromised email account, which was used to send the malicious link to contacts. Implementing two-factor authentication and using a password manager can help prevent such incidents. Users should be cautious of any email invitations that require downloading and running installer files.

How to Install McAfee Antivirus on Windows 11 or 10

Installing third-party antivirus software like McAfee on Windows 11 can be challenging due to the built-in Windows Security, which can complicate the installation process. Users may face issues such as silent failures from conflicting software, permission problems on restricted machines, or restrictions due to S Mode on new laptops. Windows 11 includes Windows Security, which is effective for malware protection, but McAfee may be necessary for compliance, additional features, or centralized protection for multiple devices. McAfee supports Windows 11 Home, Pro, and Education editions but not Enterprise. The minimum hardware requirements include a processor of 1 GHz or faster, at least 2 GB of RAM (4 GB recommended), 1.3 GB of free disk space, an internet connection for download and updates, and a display resolution of at least 1024×768. McAfee requires a persistent internet connection for activation and updates. Before installing McAfee, users should check if their device is in S Mode, as McAfee cannot be installed in this mode. They must remove any existing antivirus software completely, as leftover files can interfere with the installation. Users should also ensure that Windows 11 is up to date and verify that there is enough disk space available. To download McAfee, users should go directly to the McAfee trial page to avoid scams. After downloading, they need to run the installer and restart their computer after installation. Users should then activate McAfee, run a manual update, and conduct a full system scan. Common installation problems include freezes during download, errors due to S Mode, and issues with Windows Security not recognizing McAfee as the active antivirus. Users can verify that McAfee is functioning correctly by checking the system tray icon, Windows Security settings, and the McAfee dashboard. To uninstall McAfee, users should go to Settings > Apps > Installed Apps, select McAfee, and follow the prompts to remove it. After uninstallation, Windows Security will reactivate automatically. McAfee offers several plans for Windows users, including Basic, Essential, Premium, and Advanced, each with different features and device limits. The Basic plan is suitable for single-device users without additional needs, while families may benefit from the Essential or Premium plans.

Kimsuky Spreads DocSwap Android Malware via QR Phishing Posing as Delivery App

A new Android malware campaign has been launched by the North Korean threat actor Kimsuky, introducing a variant called DocSwap. This malware is distributed via QR codes on phishing websites that impersonate CJ Logistics. Attackers use QR codes and notification pop-ups to lure victims into downloading the malware, which decrypts an embedded APK and activates Remote Access Trojan (RAT) capabilities. The malicious app is disguised as a legitimate application to bypass Android's security measures. Victims are tricked into installing the app through smishing texts or phishing emails that mimic delivery companies. The app downloads an APK named "SecDelivery.apk," which then loads the malware. It requests permissions to access various device functions and registers a service that simulates an OTP authentication screen. The app connects to an attacker-controlled server, allowing execution of commands such as logging keystrokes, capturing audio, and gathering sensitive information. Additionally, two other malicious samples have been identified, disguised as a P2B Airdrop app and a trojanized version of the BYCOM VPN app. The campaign also includes phishing sites mimicking popular South Korean platforms to capture user credentials.

The digital impersonators: How cybercriminals hijack your brand to launch malvertising attacks

Brand trust is highly valued by consumers, leading cybercriminals to exploit it through malvertising, which embeds malicious code in legitimate ads. Malvertising can redirect users to phishing sites or download malware. Cybercriminals create fake ads that mimic trusted brands, targeting high-traffic moments and using real-time bidding to distribute these ads on reputable sites. The process involves setting up fake accounts, creating convincing ads, purchasing ad space, and delivering malware through exploit kits. The consequences include identity theft and financial loss for consumers, and reputational damage for brands. To protect against these threats, organizations should implement regular software updates, continuous employee training, protective tools, and consider partnering with managed service providers for enhanced security measures.

3,000+ YouTube videos deliver malware disguised as free software

YouTube has been identified as a platform for a sophisticated malware distribution network known as the Ghost Network, which has been active since 2021 and surged in activity in 2025. This network uses over 3,000 videos disguised as software cracks and game hacks to spread information-stealing malware, targeting users searching for free software or cheat tools.

Signal Messenger Impersonated in ‘ProSpy’ Android Spyware Campaign

ESET researchers have identified two Android spyware campaigns, ProSpy and ToSpy, which masquerade as secure messaging apps, Signal and ToTok. These malware families were first detected in June 2025 and are distributed through phishing websites and fake app marketplaces. ProSpy, which mimics a “Signal encryption plugin” or an enhanced ToTok, extracts sensitive user information, including SMS messages, contacts, and device metadata, after gaining permissions. It disguises itself as “Play Services” to avoid detection. ToSpy, discovered concurrently, seeks to capture specific files related to ToTok backups and collects various document types. Both malware types maintain long-term access to infected devices and have been reported to Google, resulting in Play Protect blocking their known variants. The main targets of these campaigns are users in the United Arab Emirates.
