About the only thing that will do that is a root kit virus. The only practical repair for many of these is to low level format and reinstall Windows. Make sure you are using top notch Anti Virus.

All that will stop root kit viruses is top notch Anti Virus. There are a number of high grade AV products and that is what you need.<br />
<br />
Symantec (not Norton), Kaspersky, Trend Micro and others.

<br />
Makes me think that it's a network worm exploiting a hole in windows 7 <br />
<br />
Want to give him direction on what to packet trace for other than top talker <br />
<br />
Anyone come across this where direction can be give on what to sniff the wire for??

The cyber security specialization covers the fundamental concepts underlying the construction of secure systems, from the hardware to the software to the human-computer interface, with the use of cryptography to secure interactions. Cyber security refers to the protection of personal or organizational information or information resources from unauthorized access, attacks, theft, or data damage. This includes controlling physical access to the hardware, as well as protecting against the harm that may come via network access, data and code injection, and due to malpractice by operators, whether intentional, accidental, or due to them being tricked into deviating from secure procedures.

Cyber Security

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

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
