微软杀毒软件『企业版』MFCS升级至1.5.1993.0『附升级文件地址』

官方说明：This article describes the Microsoft Forefront Client Security (FCS) anti-malware client issues that are fixed in this update package.

Issue 1The malware landscape has evolved, requiring new techniques to fully remediate malware, including some rootkits.

Resolution

This update contains changes to the Forefront Client Security service to improve remediation of malicious software. You must apply this hotfix to enable this new feature.

Issue 2

Computers running Client Security become unresponsive and require a hard reset.

Resolution

This update corrects two issues in the mpfilter.sys kernel component used by Client Security that cause deadlocks.

Issue 3

During definition update, computers that utilize the Volume Shadow Copy service appear to hang for several minutes. This issue may occur on computers using backup software that leverages shadow copy volumes.

Resolution

This update alters how real-time protection caches files it scans within shadow copy volumes. The change reduces the amount of time needed to purge the cache during definition update.

Issue 4

Computers running Windows Vista, Windows 2008 Server, Windows 7 or Windows 2008 R2 Server, encounter a stop error with bugcheck error code 0x00000050. This stop error may occur on Windows 7 computers during the installation of Windows 7 Service Pack 1.

Resolution

This update corrects a stop error with the code 0x00000050 on computers running Windows Vista, Windows 2008 Server, Windows 7 or Windows 2008 R2 Server. If Client Security is installed on a computer, Windows 7 Service Pack 1 will check for the presence of this update or a supersending update before installing.

Issue 5

After a reboot on computers that normally have a highly utilized processor, the Client Security user interface (UI) appears hung. The condition corrects itself but may last several minutes.

Resolution

This update increases the loading priority of the antimalware engine and definitions during antimalware service start. The priority change enables the antimalware service to handle requests sooner, mitigating the UI unresponsiveness. However, this change may slightly increase boot time on limited systems by consuming more processor resources during system start.

Issue 7

Files encrypted using Novell or Steading System Software are not properly scanned during real-time protection.
