The MER tools collect the following McAfee product data from your computer, so that Technical Support can analyze and resolve issues:
  • Event logs
  • File version details
  • Files
  • Process details
  • Registry details

WebMER tool
The WebMER tool covers many McAfee products running on Windows operating systems. See KB69396 for the products and operating systems currently supported.

There is also an ePolicy Orchestrator (ePO) deployable version that uses the ePO console to run the tool on client computers. See KB69308 for details.

Click to expand the section you want to view:

  1. Download the WebMER tool:
    1. Log on to the ServicePortal.
    2. Download the WebMER tool at: https://support.mcafee.com/webmer

      You can select from the following three download formats:
      Download Format File Comment
      EXE Mer.exe None
      ZIP Mer.zip None
      ProtectedZip MerProtected.zip Password is secret

      NOTE: If you download the file as a .zip file or Protected .zip file, you must extract the tool.

  2. Run the tool on the computer for which you need the report:
    1. Right-click Mer.exe, and select Run as Administrator.
    2. Select the required Language.
    3. Click I accept the 'End user License Agreement', and then click Next.
    4. By default, WebMER detects the installed products using Auto-Detect product(s). If you want the MER results for specific products, choose Select product(s) and then select the products you want.
    5. Click Start and wait for the WebMER tool to complete.
    6. Specify the location at which to save the <Computer_Name>_X.tgz file, and then click Save.
      NOTE: If the WebMER tool is run multiple times, the file name increments the value X by 1
  3. Upload the WebMER results to McAfee:
    1. When you are prompted to Upload to McAfee, click Yes.
    2. In the SR # field, type your Service Request (SR) reference number.
    3. In the Email Address field, type your email address for this request.
    4. Click Upload. This step uploads a file with the following file name: <Computer_Name>_<Service_Request_Number>X.tgz. Files uploaded in this way are attached to the provided SR automatically, and are viewable on the ServicePortal.
Custom Sanitization
  1. Download and open the WebMER client.
  2. At the bottom of WebMER product selection page, click Configure, to access the Custom Sanitization Settings options.
  3. Custom sanitization can be achieved with either of the following options:

    Please provide regular expression in Boost Perl syntax
    • Enter regular expression (comma separated)
    • Choose a regular expression file path
      NOTE: The user can select to browse to a text file (.txt format) which contains the regular expressions. Each line in the text file will contain only one regular expression.
  4. Click Save.
  5. Click Start.
The regular expressions a user must follow are 'boost regular expressions of Perl syntax type'.

For details about Regular Expression Syntax, see http://www.boost.org/doc/libs/1_53_0/libs/regex/doc/html/boost_regex/syntax/perl_syntax.html

Regular Expression Comment
action(\w+).dll When a user wants to mask all '.dll' files which will start with action. In this example \w+ represents a word.
(\w+)\.saleszone\.internalzone\.com When a user wants to mask all server addresses which have the domain 'saleszone.internalzone.com'.
You can run the WebMER tool from Windows Explorer, but you can also start it from a command line. When you run the MER tool from the command line, you can use the following parameters:
Switch Function
/save [path] Saves MER results to the full path specified.
Provides help for the command line.
/listproducts Lists supported products.
/detected Collects MER for installed McAfee products.
/prods Selected products for running MER.
/logs Number of days of Application Logs, System Logs, and Security logs, to collect. Specify -1 to avoid collection for any of the event logs.
/silent MER runs in silent mode.
/sanitize Remove IP address, MAC address, Domain names, and Computer names from the MER result file.
/sr [SR number] Upload results to the provided SR number.

Example 1: MER.exe /detected /save c:\mer.tgz /silent
Example 2: MER.exe /prods "VirusScan Enterprise" /save c:\mer.tgz
Example 3: MER.exe /detected /save c:\mer.tgz /sr 1-123456789 /sanitize
