Avast Antivirus: What US Users Need to Know Right Now

Avast Antivirus is a widely used security tool for Windows, macOS, and Android in the U.S., functioning primarily as a real-time malware scanner that protects against threats like viruses and ransomware. The free version for Windows includes on-access scanning and web-shield protection, while paid versions offer additional features such as a firewall, ransomware shield, and VPN. On macOS, it focuses on malware detection and web protection, and on Android, it includes app-permission monitoring and device location features. Avast has faced criticism for its data-collection practices, particularly its past monetization of user data through a subsidiary, Jumpshot, which was discontinued in 2020. Despite improvements, it still collects telemetry and usage data. Avast is suitable for users looking for an easy-to-use antivirus solution at low cost, particularly those using Windows PCs for everyday tasks. However, it may not be ideal for privacy-conscious users or those with older hardware, as it can slow down system performance. Avast competes with other antivirus providers like Norton, McAfee, Bitdefender, and Kaspersky, each offering various features and performance levels. The company is a subsidiary of Gen Digital, which consolidates multiple cybersecurity brands, and its growth potential is influenced by user retention and regulatory scrutiny. Users should weigh their priorities regarding cost, privacy, and performance when deciding on antivirus solutions.

‘Unlimited Attack Vectors’—All Windows Versions At Risk From New Flaw

Microsoft is facing a significant security vulnerability in its Windows operating system known as PhantomRPC, which allows for privilege escalation. Cybersecurity experts have expressed concern over the company's delayed response in issuing a patch for this flaw. The vulnerability resides within the Windows Remote Procedure Call (RPC) architecture and enables processes with impersonation privileges to elevate their permissions to SYSTEM level. Researcher Haidar Kabibo identified five distinct paths for exploitation, which require user interaction, coercion, or compromise of background services. Despite disclosing the vulnerability to Microsoft in September 2025, the company categorized it as moderately severe and did not issue a patch or a Common Vulnerabilities and Exposures (CVE) listing. Microsoft stated that the technique requires an already-compromised machine and emphasized the importance of following security best practices. Experts have criticized Microsoft's lack of action, arguing that it is operationally negligent and places the burden of risk management on users. In the absence of a patch, security professionals recommend focusing on access control and environmental hygiene to mitigate the risks associated with the vulnerability.

New Windows RPC Vulnerability Lets Attackers Escalate Privileges Across All Windows Versions

PhantomRPC is a significant architectural vulnerability in the Windows Remote Procedure Call (RPC) framework that allows local privilege escalation to SYSTEM-level access across all Windows versions. Discovered by Kaspersky's Haidar Kabibo at Black Hat Asia 2026, this vulnerability stems from the RPC runtime's failure to verify the legitimacy of a responding server during calls to offline or disabled servers. Attackers can exploit this by setting up a malicious RPC server that impersonates a legitimate endpoint, using the RpcImpersonateClient API to escalate privileges from low-privileged accounts to SYSTEM or Administrator levels. Five distinct exploitation paths have been identified: 1. gpupdate.exe coercion: An attacker can intercept an RPC call made by the Group Policy Client service when executing gpupdate /force, granting SYSTEM-level access if TermService is disabled. 2. Microsoft Edge startup: Launching msedge.exe triggers an RPC call to TermService, allowing privilege escalation from Network Service to Administrator via a spoofed endpoint. 3. WDI background service: The Diagnostic System Host polls TermService regularly, enabling an attacker to exploit this without user interaction. 4. ipconfig.exe and DHCP Client: Running ipconfig.exe initiates an RPC call to the DHCP Client service, allowing a Local Service attacker to elevate privileges if DHCP is disabled and a fake server is present. 5. w32tm.exe and Windows Time: An attacker can expose a named pipe endpoint, allowing them to impersonate any privileged user executing the Windows Time executable. The vulnerability was reported to Microsoft on September 19, 2025, but Microsoft categorized it as moderate severity and closed the case without a patch, as the attack requires SeImpersonatePrivilege, which is granted by default to certain accounts. Organizations are advised to implement defensive measures such as enabling RPC monitoring, ensuring legitimate services are running, and restricting SeImpersonatePrivilege. Kaspersky has provided tools for auditing environments for exploitable RPC call patterns through the PhantomRPC GitHub repository.

Best Free Antivirus 2026: Keep Your Devices Safe With These Free Tools

Many free antivirus services monetize user attention or data, and caution is advised when selecting these options. Recommended free antivirus tools should be free of ads or spyware. Trustworthy antivirus providers present clear privacy policies detailing data collection and sharing practices. Effective free antivirus tools offer real-time protection, on-demand malware scans, and user-friendly features. While free antivirus software is generally sufficient, paid options provide additional cybersecurity tools. The best free antivirus tools consume less than 5% of system resources, with active scans ideally not exceeding 40% CPU usage. Avast faced backlash for selling customer data to over 100 third parties and was fined million by the FTC in 2024. Kaspersky was banned in the U.S. in 2024 due to concerns about potential intelligence exploitation, and it cannot be recommended at this time.
