I am looking at updating but still doing a bit of research on how exactly we go about deploying the latest version of VirusScan and whether or not there are any problems with it. Same for the new version of EPO.
See my other thread: http://community.mcafee.com/showthread.php?t=233708
The default CPU usage limit for McAfee On-Access scans is 30 percent. However, when McAfee scans a network drive the antivirus is forced to use a third-party driver that does not respect the 30 percent limitation.
Therefore, if you permit McAfee to scan the network drives, McAfee will use all available CPU time to scan as much of the network as the computer has access to.
McAfee on the network servers already scans the network drives in real time. The network drives derive no additional benefit from being scanned by workstations.
To disable scanning of network drives by a workstation, follow this procedure from the affected workstation:
1. Right-click the McAfee icon in the system tray
2. Select VirusScan Console from the popup menu
3. Right-click On Access Scanner in the VirusScan Console
4. Choose Properties from the popup menu
5. Locate a blue CD or DVD icon in the long vertical window on the left side of the On-Access Scan Properties window, and click the CD icon
6. On the top right of the On-Access Scan Properties window, click the Scan Items tab
7. Clear the checkmark from "On network drives" if it is present. This will prevent this workstation from scanning network places (as in My Network Places in Windows Explorer). However, mapped network drives must be specifically excluded.
8. On the top right of the On-Access Scan Properties window, click the Exclusions tab
9. Click the Exclusions… button in the What not to scan area
10. In the Set Exclusions window, click Add…
11. Click Browse…
12. Click My Computer in the Browse for Folder window
13. Select a mapped network drive. You will need to add each mapped drive to the exclusion list individually. Even though you have cleared the network drives from the Scan Items tab, mapped network drives will still be scanned if you do not specifically exclude them. Overlapping mapped drives will be scanned for each time the drive is mapped.
14. Click okay when you have a mapped drive selected. This will return you to the Add Exclusion Item window.
15. Check off the Also Exclude Subfolders checkbox. This box must be checked since mapped drives generally have the bulk of the data organized in subfolders.
16. Click okay
17. Verify that the mapped drive is listed in the Set Exclusions window
18. Repeat steps 10 to 17 until all of your mapped network drives are excluded from virus scans
19. Click okay on the Set Exclusions window
20. Click okay on On-Access Scan Properties
21. Close the VirusScan Console
