![]() ![]() The cluster quorum database and other files for database availability groups (DAGs). Unified Messaging is not available in Exchange 2019. Folder exclusionsĮxclude the following folders from file-level scanning and memory-resident scanning on Exchange servers. To learn how to open the Exchange Management Shell in your on-premises Exchange organization, see Open the Exchange Management Shell. The locations of many of these Exchange folders are configurable in the Exchange Management Shell. Note: The %ExchangeInstallPath% value is typically C:\Program Files\Microsoft\Exchange Server\V15\ (includes a trailing "\"), the %SystemRoot% value is typically C:\Windows (doesn't include a trailing "\"), and the %SystemDrive% value is typically C: (doesn't include a trailing "\"). When you deploy a Windows antivirus program on an Exchange server, make sure that the folder exclusions, process exclusions, and file name extension exclusions that are described in these sections are configured for both memory-resident and file-level scanning. Recommended exclusions for Windows antivirus programs on Exchange servers Therefore, excluding these files from being scanned by the Windows antivirus program is very important.Īnother issue is that Windows antivirus programs can't replace email-based antispam and antimalware solutions because Windows antivirus programs that run on Windows servers can't detect viruses, malware, and spam that are distributed only through email. This can cause severe failures in Exchange Server, and it might also generate 1018 event log errors. The biggest potential problem is a Windows antivirus program might lock or quarantine an open log file or database file that Exchange needs to modify. Some antivirus programs start an on-demand scan automatically after the virus signatures are updated to make sure that all files are scanned with the latest signatures. Memory-resident scanning or real-time protection monitors all files and processes that are loaded and running in a computer's active memory.įile-level scanning refers to checking files on the hard disk for viruses manually or on a regular schedule. There are two basic components of any Windows antivirus program: However, if they aren't configured correctly, Windows antivirus programs can cause problems in Exchange Server. More detail regarding the deployment of CylancePROTECT to Windows and Linux computers will be sent later this summer.When you run Windows antivirus programs on Microsoft Exchange servers, you can help enhance the security and health of your Exchange organization. ![]() After the two-week review, we will convert it to blocking mode and then remove McAfee from those systems. It will run initially in monitoring mode only. Mac users will begin to see the Cylance application on their IT managed computer. We are releasing Cylance to all Macs over the next few weeks in preparation for the end of our McAfee subscription. We have deployed Cylance only to OIT computers to review the behavior and effectiveness of the application. The product is much more effective but does shift some of the oversight responsibility to the IT security administrators. Certain applications that are benign yet exhibit some of these behavioral patterns can be whitelisted for the organization at the administrator level. Rather than relying on particular virus definitions, Cylance targets behavioral patterns of threatening applications. Cylance is a robust and powerful application that blocks virus and malware threats before they take hold. OIT is currently testing a new antivirus application called CylancePROTECT.
