Best Antivirus for Windows XP: Options That Still Work

Finding a reliable antivirus solution for Windows XP is challenging due to the lack of support since 2014. Major antivirus vendors have withdrawn compatibility, leaving limited options. Panda Security continues to support Windows XP with its Panda Dome antivirus, which offers real-time protection and a cloud-based engine. Antivirus software can block known malware, flag suspicious activity, and stop recognized threats, but it cannot patch the operating system itself. Users have fewer choices for protection as new vulnerabilities emerge. Several antivirus tools compatible with Windows XP include: - Panda Dome: Actively maintained, offers real-time protection, free and paid plans available. - Avast (v18.8): Limited support, last updates in October 2024, free legacy version only. - AVG (v9): Discontinued in 2019, operates offline, free legacy version only. - ClamWin: Open-source, actively maintained, no real-time protection, free. - 360 Total Security: Active legacy version, multi-engine approach, real-time protection, free and premium options. - Malwarebytes (legacy): Only older versions support XP, best as a supplement, free legacy version. - VirIT eXplorer Lite: Actively maintained, free lite version with real-time protection. Choosing the right antivirus requires consideration of internet connectivity, hardware age, update status, and whether to use free or paid options. For most users, Panda Dome is recommended for its active support and real-time protection. To enhance security on Windows XP, users should keep machines offline when possible, use ad blockers, be cautious with emails and links, avoid fake antivirus downloads, transfer files via USB from modern computers, and keep third-party software updated.

Hackers Use Fake VLC Executable and Malicious libvlc.dll to Deploy ValleyRAT

Cybercriminals are using a sophisticated method to bypass security measures by embedding malware within the VLC media player. This campaign exploits VLC to install ValleyRAT, a remote access trojan, through phishing emails that contain links to download a seemingly harmless file. Once the file is opened, it activates a hidden backdoor that evades detection by antivirus solutions. The malware has been active since 2023, with a significant increase in activity noted through 2025 and into 2026, particularly targeting Chinese and Japanese-speaking users. The infection process begins when a victim clicks a link in a phishing email, leading to a ZIP archive containing a disguised executable and a malicious DLL (libvlc.dll). The executable mimics a legitimate VLC file, and when executed, it loads the DLL, allowing the malware to run under the guise of VLC. The malware establishes persistence by creating a registry entry and connects to a remote server to retrieve the final payload. ValleyRAT employs evasion tactics to avoid detection, such as performing checks on system behavior and using a fileless approach to inject its payload directly into memory, avoiding storage on disk. Researchers recommend training employees to recognize suspicious filenames and deploying endpoint detection tools to identify DLL sideloading behavior. For organizations affected by this campaign, isolating compromised systems and reviewing security logs are critical initial steps. Indicators of compromise include a malicious email domain, a ZIP archive containing a fake VLC executable, and a download URL for ValleyRAT.

Antivirus vs malware: Why antivirus alone is no longer enough

Antivirus software is still essential for cybersecurity, as it effectively detects and removes traditional malware infections. However, cybercriminals have evolved their tactics, using methods such as fake delivery notifications and phishing attacks that may not involve malicious software detectable by antivirus programs. Experts recommend a layered approach to online security, which includes keeping software updated, using strong passwords, enabling multi-factor authentication, being cautious with emails, backing up files, and using secure internet connections. A virtual private network (VPN) complements antivirus software by encrypting internet connections and providing additional security features. Relying solely on antivirus software is no longer sufficient for protecting against modern cyber threats.

From monolith to Lakebase to LTAP: rethinking the database from storage up

Sixteen years ago, the author began their PhD at UC Berkeley and was advised to focus on analytics rather than OLTP databases, which were considered solved. This led to the creation of Apache Spark and Databricks. However, during the development of Databricks, it was found that OLTP databases were not solved problems; they were difficult to scale and fragile. This realization led to the development of Lakebase, a serverless Postgres database designed with modern technology. Lakebase architecture separates the write-ahead log (WAL) and data files into independent, scalable services. The WAL is externalized to a service called SafeKeeper, which uses Paxos-based replication for durability, while data files are managed by PageServer, which stores them in cloud object storage. This design addresses challenges such as data loss, scaling, and performance interference between transactional and analytical workloads. Lakebase maintains compatibility with Postgres, offers unlimited storage, serverless compute, durable writes, and simpler high availability. It also introduces LTAP (Lake Transactional/Analytical Processing), which allows both transactional and analytical processing to operate on a single data copy in real time, eliminating the need for separate data copies and reducing costs. LTAP utilizes a unified storage layer that allows data to be materialized in both row and columnar formats, optimizing it for both transactional and analytical workloads. The system ensures that analytics can access the most current data without affecting transactional performance by using a log sequence number (LSN) to retrieve the latest changes. Unlike traditional CDC approaches, LTAP requires no explicit table replication, as all data is stored in a single governed copy. This architecture circumvents common issues faced by hybrid transactional/analytical processing (HTAP) systems, such as incomplete feature sets, lack of ecosystem support, and performance contention. The Lakebase architecture has unlocked capabilities like unlimited storage, elastic compute, durable writes, and instant branching, with ongoing developments anticipated in the future.

Lakebase also introduces LTAP (Lake Transactional/Analytical Processing), which enables transactions and analytics to operate on a single data copy in real-time, avoiding the need for separate data copies and reducing costs. The system retains Postgres's ACID semantics while storing data in open columnar formats, making it accessible to both transactional and analytical engines without the delays and complexities of traditional replication methods. The architecture allows for unlimited storage, serverless compute, and instant branching, while ensuring that analytics can read the most current transactional data without affecting transactional workloads. LTAP aims to unify transactional and analytical processing by leveraging distinct compute engines for each workload while integrating at the storage layer.
