ESET Technical Alert - Microsoft 979223 for Windows 7/Server 2008 R2

Microsoft has notified software vendors that a hotfix is now available for Windows 7 and Windows Server 2000 R2 to resolve a memory leak in Windows Filtering Platform (WFP). WFP is a technology Microsoft provides to developers of network, security and utility software for monitoring network traffic. Some customers using ESET Smart Security on Windows 7 or Server 2008 R2 may see an increase in program memory usage over time resulting in decreased system performance. The impact of this issue on clients is difficult to determine because it is based on the type and amount of network traffic performed, which varies from customer to customer. A detailed description of the problem, along with instructions on how to obtain the hotfix, can be found in Microsoft Knowledge Base Article #979223, "A nonpaged pool memory leak occurs when you use a WFP callout driver in Windows 7 or in Windows Server 2008 R2." (NOTE: The hotfix can be requested from this page on Microsoft’s web site. Select "Show hotfixes for all platforms and languages" on the web page to view which platforms the hotfix is available for and to select them.) ESET recommends customers request this hotfix from Microsoft and deploy it as soon as possible after verifying compatibility with their operating environments.
