What is the best PC antivirus for 2026: Acronis True Image vs. competitors

In 2026, traditional antivirus solutions are becoming outdated due to the rise of sophisticated cyber threats, including AI-driven ransomware and advanced phishing schemes. The FBI Internet Crime Report states that cybercrime losses exceeded .5 billion in 2023, with projections by Cybersecurity Ventures estimating costs could reach trillion annually by 2025. Research from IBM shows that organizations without a tested recovery plan face higher costs and longer downtimes. Built-in protections like Windows Defender and MacOS XProtect offer basic security but may leave gaps, necessitating comprehensive third-party antivirus solutions. Acronis True Image is highlighted for its unique combination of real-time malware protection and full system backup capabilities, enabling users to recover quickly from incidents. Other leading antivirus solutions, such as Norton 360, Bitdefender, McAfee, and Kaspersky, excel in threat prevention but lack integrated recovery options. Acronis emphasizes the importance of both security and continuity, preparing users for both cyber incidents and everyday failures.

Fake Grok app built using generative AI discovered spreading malware on macOS devices

Recent concerns have been raised about the Grok AI chatbot, associated with Elon Musk, due to reports of explicit and degrading content. A new strain of malware targeting Apple computers, linked to vulnerabilities in the Mac App Store, has been identified as part of the SimpleStealth campaign. Users are advised to download applications only from the official app store or reputable companies, as Grok is not considered reputable. Many antivirus programs have difficulty detecting this malware variant, making robust Mac antivirus software a wise investment. Apple's built-in security software, XProtect, provides some protection, but users should remain vigilant and enhance their cyber hygiene.

Why Your Apple Device Isn’t as Invincible as You Think

Many Apple users believe that their devices are nearly impervious to malware and cyber threats, but this is a misconception. While macOS has built-in protections like Gatekeeper and XProtect, no system is completely foolproof. Cybercriminals are increasingly targeting Macs, and users can fall victim to phishing schemes, ransomware, and other malware. Antivirus software for Mac provides an additional layer of defense, detecting malware and blocking phishing attempts. It can also protect sensitive information and offer features like secure browsing and Wi-Fi protection. Regular software updates and cautious behavior are essential for security, but relying solely on these measures is risky. Integrating antivirus into security routines is a practical step to minimize risks.

How Your Computer Protects Itself from Viruses and Cyberattacks

Virus protection is essential in the digital landscape due to threats like ransomware, phishing, spyware, and trojans that can compromise personal data and financial security. Cybercriminals continuously innovate, leading to potential malware infections that can steal sensitive information, lock files for ransom, or degrade device performance. Windows includes Microsoft Defender Antivirus, which provides real-time protection, automatic updates, cloud-based scanning, and firewall features. macOS offers built-in security tools such as XProtect, Gatekeeper, and the Malware Removal Tool, alongside regular updates. Linux distributions like Ubuntu are designed with security in mind, featuring regular patches, AppArmor, and optional antivirus tools. Key features to look for in antivirus software include real-time scanning, firewall protection, web protection, email scanning, automatic updates, and parental controls. While built-in solutions are often sufficient for everyday users, advanced users may benefit from third-party antivirus software. Best practices for maintaining cyber hygiene include keeping software updated, avoiding unverified applications, using strong passwords, enabling two-factor authentication, and regularly backing up data.

How a single MacBook compromise spread across a user’s Apple devices

Macs are known for their reliability and security but are not immune to malware, which is becoming more sophisticated. A user named Jeffrey in Phoenix reported performance issues with his MacBook, which was used without an Apple ID due to company policy. The malware eventually affected his personal devices, prompting him to seek assistance from Apple. Signs of potential infection include sluggish performance, frequent app crashes, unusual activity in Activity Monitor, redirected web traffic, and altered security settings. macOS includes built-in protections like Gatekeeper, XProtect, System Integrity Protection, and Sandboxing, but these are not foolproof. If a Mac is suspected to be infected, users should disconnect from the internet, back up important files, boot into Safe Mode, run a trusted malware removal tool, check login items and Activity Monitor, consider a clean reinstall of macOS, secure other devices, reset passwords, and seek professional help if needed. To prevent infections, users should install strong antivirus software, consider personal data removal services, use a password manager, enable two-factor authentication, keep macOS and apps updated, review login items and background processes, and use identity theft protection services.

This dangerous Mac malware just got a major upgrade which makes it even harder to delete — how to stay safe

An updated variant of the Atomic Stealer malware is targeting Mac users, capable of stealing sensitive information such as keychain passwords, local files, browser cookies, credit card details, and cryptocurrency assets. This malware can establish a backdoor on compromised Macs, making them vulnerable to further attacks. It operates on a malware-as-a-service model, allowing cybercriminals to subscribe for a monthly fee. The malware includes a hidden backdoor executable named ‘.helper’ and a persistent wrapper script ‘.agent’, which executes continuously and is activated each time the infected Mac is powered on. The primary distribution channels for this malware are cracked software and spear phishing campaigns. Users are advised to avoid unauthorized software downloads and minimize personal information shared online to reduce the risk of infection. Additional antivirus solutions are recommended for enhanced protection against sophisticated threats.

I learned these 6 antivirus myths for PCs are completely wrong

Antivirus software on Windows was once essential due to security vulnerabilities, but built-in protection in Windows 8 and later versions often suffices for everyday use. Modern third-party antivirus applications are designed to be efficient and have minimal impact on system performance. All operating systems, including macOS, Linux, iOS, and Android, are susceptible to malware, contrary to the belief that only Windows needs antivirus protection. Manual virus scans are no longer necessary as modern solutions provide real-time monitoring. Antivirus software should be part of a broader security strategy that includes regular updates and secure online practices. Relying solely on cautious behavior is insufficient, as threats can emerge from various sources. Using antivirus software is still recommended, and users can complement built-in security features with third-party solutions.

Mac users once skipped antivirus software — here’s why that’s no longer a good idea

In 2024, 22 new Mac malware families emerged, up from 13 in 2022, indicating a rise in malware targeting macOS. Built-in security features include XProtect, which warns users about known malicious software; Gatekeeper, which prevents the installation of unsigned software; Sandboxing, which isolates applications to prevent unauthorized changes; Lockdown Mode, which restricts app functionality to protect user data; Safari protections against phishing and tracking; and password security measures that alert users about weak or compromised passwords. While Apple's built-in protections are robust, third-party antivirus software may provide additional security layers. Users are advised to practice good security habits, keep software updated, avoid unverified apps, and use a VPN on public Wi-Fi.
