MacPaw Moonlock

Moonlock is a new antivirus solution for Mac developed by MacPaw, utilizing technology from CleanMyMac. It features a basic VPN, security configuration scan, and an elegant user interface, but some functionalities may not perform as expected. The annual subscription for a single Mac is priced higher than competitors like CleanMyMac and G Data Antivirus. Moonlock requires macOS 13 (Ventura) or later for compatibility. Setting up the app involves creating an account and granting permissions, with a full scan recommended post-installation. In independent lab tests, Moonlock scored 5.5 out of 6 in protection and 6 in usability, but its performance rating was 4.5 points, lower than competitors. The Security Advisor feature provides advice on enhancing security, while the System Protection feature identifies areas for improvement. Moonlock includes a basic VPN with 61 server cities in 50 countries. Its Network Inspector focuses on blocking traffic from specified countries, but its effectiveness is questionable. Flexible scan scheduling is available, but it does not guarantee the removal of Windows malware. The app includes informational panels and animated videos, but it currently lacks effective phishing protection, failing to block known fraudulent websites.

K7 Antivirus for Mac

K7 AntiVirus for Mac provides basic malware elimination but lacks essential features such as browser-level protection, which is critical for user safety against malicious websites. Its Windows version offers more comprehensive features, including a firewall and exploit protection, while being priced significantly lower than the Mac version. K7's pricing for Mac subscriptions is competitive, with a one-Mac subscription costing less than average market prices. The software is compatible with older macOS versions, dating back to Yosemite (10.10). K7 has not participated in independent testing labs, which limits its evaluation compared to competitors that have received high scores. The installation process is straightforward, and K7 performs full scans quickly, but it does not offer a quick scan option. K7 lacks protection against phishing attacks and does not detect Windows malware, which is a feature present in many competing antivirus solutions.

‘BrowserVenom’ Windows Malware Preys on Users Looking to Run DeepSeek AI

A new strain of Windows malware called "BrowserVenom" is exploiting interest in DeepSeek's AI models by targeting users through deceptive Google ads.

The operation is believed to involve Russian-speaking threat actors, and the malware has infected users in several countries, including Brazil, Cuba, Mexico, India, Nepal, South Africa, and Egypt. The fraudulent domain has been suspended, but the malware can evade many antivirus solutions. Users are advised to verify official domains when downloading software.

Intego Mac Internet Security

PCs were introduced before Apple’s Macintosh, leading to the emergence of PC viruses and the establishment of antivirus companies, with Macintosh protection being less prioritized. Intego focused on Macintosh security from the start, offering Intego Mac Internet Security, which includes a firewall that manages network permissions and defends against external attacks. Intego has been effective against Mac malware, achieving a 99.1% malware detection score in independent lab tests, although it lacks phishing protection, a feature offered by competitors Norton 360 Deluxe and Bitdefender Antivirus Plus. Intego's pricing is competitive, with a standard annual fee of .99 for a single license and .99 for three licenses. A five-device subscription costs .99, while the Mac Premium Bundle starts at .99 annually and includes additional features. A 14-day free trial is available, and free alternatives like Avast and AVG are also on the market. Intego supports older macOS versions back to Mavericks (10.9), but the latest version requires High Sierra (10.13) or later. The installation process for Intego is straightforward, requiring a restart and granting necessary permissions. The main interface includes components for updates, firewall, and antivirus, with user-friendly access to scanning options. Intego has received certification from AV-Comparatives and detected 100% of Windows malware samples in tests. Its quick scan takes about two and a half minutes, while a full system scan takes seven minutes. Intego's Safe Browsing feature checks existing browser protections but lacks a dedicated antiphishing solution. The NetBarrier firewall allows users to classify their network and manage traffic permissions effectively, although it may be complex for some users.

This dangerous new Windows malware hides from your antivirus while impersonating a popular PC brand

A new strain of malware called CoffeeLoader targets Windows users by pretending to be an ASUS utility, specifically imitating ASUS's Armoury Crate. It has sophisticated evasion techniques that allow it to bypass antivirus software. Once installed, it deploys infostealers like Rhadamanthys Infostealer to extract sensitive information. CoffeeLoader operates undetected by executing code on the GPU instead of the CPU, using Call Stack Spoofing to disguise its activities, and employing Sleep Obfuscation to encrypt itself in memory when inactive. It also exploits Windows Fibers to evade detection. To protect against CoffeeLoader, users should download Armoury Crate only from the official ASUS website and be cautious of deceptive links and ads that may lead to malware installation.

Webroot Premium

PCMag editors independently select and review products. Webroot Premium combines device-level protection with identity theft tracking and remediation, but its antivirus protection is limited compared to competitors. Webroot Premium costs .99 per year for five devices and one identity, with a family edition available for .99 covering ten devices and identities. Other competitors like Bitdefender Ultimate Security and Norton 360 With LifeLock offer more comprehensive features at similar price points. Webroot AntiVirus has been rebranded as Webroot Essentials, and older versions have been phased out. The installation process for Webroot Premium is straightforward, and it includes a firewall that monitors network activity.

Webroot provides 24/7 support for identity restoration, with a monetary guarantee for remediation services up to million for ten family members.
