The Payment Card Industry Data Security Standard (PCI DSS) is a set of industry regulations imposed by the major credit card companies to ensure the safety, security, and integrity of cardholder data. Any business that processes, stores, and transmits cardholder account data must comply with this complex new standard, and must be able to demonstrate that compliance through automated and manual audits of their systems. This white paper looks at the key challenges and requirements of PCI DSS as it relates to Microsoft Windows and Active Directory, and shows you how a third-party software solution can help with PCI compliance.

There are many compelling reasons for virtualizing Windows and Linux applications. Virtualization improves server utilization by allowing you to run multiple workloads on a single physical server. It reduces the number of physical servers you have to maintain, while allowing you to use less physical space and power while still improving scalability. All of these capabilities translate directly into lower costs, less complexity, and greater flexibility in your mixed IT environment.

What do I do if I suspect someone is controlling my PC? When my IP address has been changed without my knowledge? My boot-up
process is getting harder unless I unplug the Ethernet cable and the CPU is at 100% every time I open any program. There is
also a new connection to the Internet that is between my connection and the net I know was not there a month ago. When I try
to register my e-mail address the programs say it's invalid and does not match whatever it has to compare it to.

It sounds like some spyware or other unwelcome software has gotten installed on your computer. You need to do some process of elimination to see where the problem is. I would recommend that you start the computer without the Ethernet cable being connected and to start up the operating system on your computer in "safe" mode to minimize what is getting automatically started.
If you are comfortable with using a network sniffer such as Wireshark or one of the commercially available packages, try putting a hub (not switch) between the infected computer and your internet connection and let Wireshark tell you what it is finding. This could help in identifying the exact cause of the problem and serve as a good learning experience in terms of doing some detective work on finding the cause of a problem.
On a different computer, download several different anti-spyware utilities such as Spybot and Ad-Aware. There are several very good packages out there to choose from. The main thing is to run at least two different packages, preferably three, because no single app will remove all the spyware in the wild these days.
Burn these apps onto a CD and then install them onto the computer you have booted into safe mode. Since you are running without a network connection for the time being, you will also need a way to download any signature or other updates and install those before running the software for the first time. After you have run each of the spyware detection programs once, run them at least one more time apiece until you have a clean report from each. This may sound like extra work, but I have seen where one spyware removal program will remove a particular package allowing the same or different spyware removal package to see another piece of spyware/adware that went previously undetected.
