Background for this topic.
A computer virus is malware that replicates by inserting its code into other programs or files. When an infected file runs, the virus may modify additional files on the same system and, in some cases, reach other systems through shared storage, removable media, or network access. The term is often used broadly in news, but technically it describes self-replicating, host-dependent malware rather than malware in general.
Viruses matter because infection can alter legitimate software, corrupt data, or provide a foothold for further malicious activity. Security teams should treat unexpected file changes, repeated detections, and unexplained program behavior as indicators for investigation. Useful controls include regularly patched systems, endpoint protection that detects suspicious file modification and execution, restricted use of removable media, and application controls that limit unapproved code. During an incident, isolate affected hosts, preserve samples and relevant logs, identify the original execution path, and restore only from verified clean sources.

AI worms, or "viruses with wings and brains," adapt to new environments, seek out vulnerabilities, and will likely strike within a year, researchers say.
Cybersecurity researchers have disclosed details of a new dual-vector campaign that leverages stolen credentials to deploy legitimate Remote Monitoring and Management (RMM) software for persistent remote access to compromised hosts
A new theory from the agency that brought us ‘America hacked itself to blame Beijing’ China’s National Computer Virus Emergency Response Center (CVERC) has alleged a nation-state entity, probably the USA, was behind a 2020 attack on a bitcoin mining operation and by doing so has gone into bat for entities that Beijing usually blasts.…
Security pros explore whether infection-spoofing code can immunize Windows systems against attack Feature What's better, prevention or cure? For a long time the global cybersecurity industry has operated by reacting to attacks and computer viruses. But given that ransomware has continued to escalate, more proactive action is needed.…

Citing Security Concerns, Australia Joins Others in Banning Anti-Virus ProductsThe Australian Department of Home Affairs on Friday banned the use of Kaspersky Labs products in public offices citing an "unacceptable security risk" to the government networks and data. All government offices must uninstall all Kaspersky products and report the completion of the task to the agency.

Imagine this... You arrive at work to a chaotic scene. Systems are down, panic is in the air. The culprit? Not a rogue virus, but a compromised identity. The attacker is inside your walls, masquerading as a trusted user. This isn't a horror movie, it's the new reality of cybercrime. The question is, are you prepared? Traditional incident response plans are like old maps in a new world. They
