Mcshield怎么这么占cpu？

rucstudent

特别是开机一会，CPU占用非常不稳定，一下到59％一下到2％，感觉有点卡，不过过后就好些了。
另外在打开N个网页的时候也回卡，但是不是特别多，用greenbrowser打开4，5个网页，有时候就会上升到90％....呵呵
对了，5200的引擎有什么改进吗？

我也有过LZ的这种情况

那年我们还小

偶尔冲高会回落的

解决VsTskMgr.exe占CPU将近100%的Hotfix


我的机器刚才又出现VsTskMgr.exe占CPU将近100%的情况,到McAfee的网站查询,发现了这个hotfix,它并没有被包含在8.5i的patch 1里面,附件就是这个Hotfix,希望对大家有用.

注意:Hotfix和Patch不同,并不是发给所有用户使用的,而是由技术支持人员发给某一类用户解决某一单独问题的,并且不保证完全通过QA.如果不放心使用,请等待Patch2

VsTskMgr.exe and McShield.exe cause high CPU usage during DAT Update

Environment

McAfee VirusScan Enterprise 8.5i
Microsoft Windows

Problem

The following processes use up to 98% CPU (this generally lasts 4-8 minutes) during a local or ePO-managed AutoUpdate session:



vstskmgr.exe
mcshield.exe

Microsoft Outlook can also spike the CPU utilization in excess of one minute.


Change or Cause

The McTaskManager service (vstskmgr.exe) is notified when virus definition (DAT) files are replaced. Vstskmgr.exe then notifies all scanner components to reload the DATs. The issue occurs when vstskmgr.exe receives multiple notifications that the DATs have been replaced, and attempts to reload the DATs for each scanner.

Solution


This issue has been resolved with HotFix 320829, which is attached to this article.

IMPORTANT: This HotFix is not included in VSE8.5i Patch 1. The HotFix should be installed post installation of Patch 1.

NOTE: After the HotFix is applied allow up to 15 second after a DAT update before verifying the DAT information has been populated throughout the product.

For example, in About VirusScan Enterprise screen, an older DAT created on: date may be displayed for up to 15 seconds after an update .


This issue will be resolved in McAfee VirusScan Enterprise 8.5i (VSE8.5i) Patch 2. A release date cannot be given for this Patch at this time as it is currently on limited release for evaluation. This article will be updated once Patch 2 is released.

This is documented in the VSE8.5i Patch 2 README.TXT under RESOLVED ISSUES for Item 1.

1. ISSUE:
When an AutoUpdate task copies new DAT files
into the engine folder, VirusScan services and
Microsoft Outlook can spike CPU utilization in
excess of one minute.

RESOLUTION:
The McTaskManager service has been enhanced so
that it no longer issues multiple reload
notifications to the scanners after a DAT
update.
NOTE:
Users who saw a smaller spike after the original
fix (HF320829) should see more improvement with
this fix.s

设置咖啡只是写入数据的时候才扫描.  平时读取本机数据时不扫描.  
在按访问扫描设置中应该有这个选项.

不错，这样做在保持安全性的同时也降低了不少的资源率（我一向也就是这么设置的，感觉很好）

在“按访问属性”的“检测项”里可更改这个监控的扫描方式

应该是偶尔的吧 我一直很正常  除了开机速度较慢 很少出现因为咖啡而占D大量的CPU的情况

设置了
我发现mcafee是在我用greenbrowser打开2～3个页面（快速同时打开的时候）
Mcshield就会上升到81%甚至91%
