After the above resolutions, additional actions may be needed. Please review the following steps.
Step 1: Update Symantec Anti-Virus definitions
Symantec Anti-Virus incorrectly flags the above listed files as malware. Please migrate to Symantec definitions dated Sept 15 or later; the false detection has been removed in Rapid Release Sequence 187381 onwards.
Step 2: Remove older versions MicTray.exe
After updating the Conexant driver package via SoftPaq ( refer to the Security Bulletin for latest SoftPaqs) or Windows Update, older versions of MicTray.exe files may exist in several folders or sub-folders such as SWSETUP, Rollback and Temp. The SWSETUP folder is created and/or updated whenever a SoftPaq is executed, so if older SoftPaqs were executed on the system, older versions of MicTray.exe would reside in this folder. The Rollback and Temp sub-folders are created when Windows performs a driver update.
These older versions of applications in these folders can be safely quarantined and deleted without any impact to the system. Before installing the updated driver package, it is recommended to remove all instances of the older MicTray.exe files. Below are some suggested steps. Actual steps may vary depending on whether multiple installations of audio drivers have occurred on the system.
  1. Execute and finish normal uninstallation procedure:
    C:\PROGRAM FILES\CONEXANT\CNXT_AUDIO_HDA\UIU64A.EXE" -S -U -G -NR -ICISSTRT.INF -OI=INTCAUDIOBUS.INF,INTCOED.INF
  2. Check for the below folders and if they exist, permanently force delete them:
    a. Rmdir C:\Windows\UCI /s /q

    b. Rmdir C:\Windows\Cnxt /s /q

    c. Rmdir C:\Program Files\Conexant/s /q

    d. For C:\SWSETUP:
    i. Please ensure that the Windows command extensions are enabled
    ii. Execute the DOS command: for /d /r "c:\SWSETUP" %a in (Conexant\) do if exist "%a" rmdir /s /q "%a"
  3. If exists, please permanently force the deletion of the following files

    a. Del C:\Windows\system32\mictray.exe /f /q

    b. Del C:\Windows\system32\mictray64.exe /f /q

    c. Navigate to: C:\Windows\Temp and execute: Del mictray*.* /f /s /q
  4. Windows also stores copies of every driver under C:\Windows\System32\DriverStore\FileRepository. Windows uses this folder to reinstall a particular version of the driver when needed. Please follow the steps below to clean up all the Conexant audio drivers from this location:

    a. Open Command Window as "Run as Administrator"

    b. From command prompt, run "pnputil.exe /e".

    c. A list of all 3rd party installed drivers in the driver store are displayed. Locate all references to "Conexant" in the list and note the value of the "Published Name". The "Published Name" will be the OEM*.INF name of the device.

    d. From command prompt, run "pnputil.exe /d %OEMINFNAME% /f" " where %OEMINFNAME% is the "Published Name" determined in Step 4.c. There may be more than 1. Need to iterate through each. This will cause the driver store package to be deleted.

    e. Example "pnputil.exe /d oem1.inf /f"
  5. Restart the computer.
  6. Install the new SoftPaq.
