It sound more like a service pack install, windows update? Do you use a management software like kaseya, kace , landesk? <br />
<br />
Did you change the GPO?<br />
<br />
Did you take one of the machines offline and check for virus? I recommend a flash drive program like hitman pro. <br />

I was apparently attacked by a virus on 6/6/2013. Drivers throughout my company began to malfunction. By the next day, every PC in our organization had startup repair issues as they were rebooted. It took only three days to bring down every server as they were rebooted over the weekend. Our backup server will not boot. I cannot find any virus definitions for our situation. Has anyone else encountered our nightmare??

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.

OS Security

A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.
