Windows Security Center uses a two-tiered approach for detection status. One tier is manual, and the other tier is automatic through Windows Management Instrumentation (WMI). In manual detection mode, Windows Security Center searches for registry keys and files that are provided to Microsoft by independent software manufacturers. These registry keys and files let Windows Security Center detect the status of independent software. In WMI mode, software manufacturers determine their own product status and report that status back to Windows Security Center through a WMI provider.

Windows Security Center will try to tell you about antivirus or firewall programs installed on your computer. However, if a manufacturer decides not to participate, the Security Center will not be able to detect the manufacturer's programs.

FAQs Windows Security Center <- this link no longer works but the above info was previously posted there.

When launching the Security Center there is a note that advises Windows does not detect all anti-virus programs. It is the responsibility of the anti-virus or firewall vendor to design their software so that it will be recognized by the Windows Security Center. The vendor also must submit the information to Microsoft so the Windows operating system catalog can be updated with the software signature addition.

However, you are also indicating that you use Norton Internet Security

Using more than one anti-virus program is not advisable. The primary concern with doing so is due to conflicts that can arise when they are running in real-time mode simultaneously and issues with Windows resource management. Even when one of them is disabled for use as a stand-alone scanner, it can affect the other. Anti-virus software components insert themselves into the operating systems core and using more than one can cause instability, crash your computer, slow performance and waste system resources. When actively running in the background while connected to the Internet, they both may try to update their definition databases at the same time. As the programs compete for resources required to download the necessary files this often can result in sluggish system performance or unresponsive behavior.

Each anti-virus may interpret the activity of the other as malicious behavior and there is a greater chance of them alerting you to a "False Positive". If one finds a virus or a suspicious file and then the other also finds the same, both programs will be competing over exclusive rights on dealing with that virus or suspicious file. Each anti-virus may attempt to remove the offending file and quarantine it at the same time resulting in a resource management issue as to which program gets permission to act first. If one anit-virus finds and quarantines the file before the other one does, then you encounter the problem of both wanting to scan each other's zipped or archived files and each reporting the other's quarantined contents. This can lead to a repetitive cycle of endless alerts that continually warn you that a virus has been found when that is not the case.

Anti-virus scanners use virus definitions to check for malware and these can include a fragment of the virus code which may be recognized by other anti-virus programs as the virus itself. Because of this, most anti-virus programs encrypt their definitions so that they do not trigger a false alarm when scanned by other security programs. Other vendors do not encrypt their definitions and they can trigger false alarms when detected by the resident anti-virus. Further, dual installation is not always possible because most of the newer anti-virus programs will detect the presence of others and may insist they be removed prior to download and installation of another. Nonetheless, to avoid these problems, use only one anti-virus solution. Deciding which one to remove is your choice. Be aware that you may lose your subscription to that anti-virus program's virus definitions once you uninstall that software.

Hi jackuars,

This is Mike from the Norton Authorized Support Team.

As "quietman7" has mentioned, you cannot have more than one anti virus/internet security application installed at the same time. Doing so will cause problems with Windows Security Center and also leave your system more vulnerable to infection and can also lead to false positives. Norton Internet Security is a full-featured internet security suite that not only contains protection against visuses, spyware and malware, but also contains the Norton Firewall. You should remove vipre antivirus+antispyware and also make sure that you do not have any other real-time security software installed.

Which version of Windows are you running? Make sure that you have all of the available Windows patches applied by running Windows Update, possibly multiple times, until you are informed that there are no more updates available. Also, which version of Norton Internet Security do you currently have installed? You can check this by opening Norton Internet Security, choose the "Help & Support" link and then choose "About". Please let me know the version of Windows and Norton Internet Security that you have installed. After you remove the other security software and restart your computer, launch Norton Internet Security and manually run LiveUpdate to ensure you have the latest updates installed. Next, complete a "Full System Scan" to check for infections.

Thank you,

Norton Internet
