freshclam.exe - Ordinal Not Found

After I upgraded ClamWin to version 0.99.1 on an HP laptop running Microsoft Windows 7 Professional, I saw a window titled "freshclam.exe - Ordinal Not Found" with the message "The ordinal 177 could not be located in the dynamic link library libclamav.dll."

freshclam.exe - Ordinal Not Found

When I right-clicked on the ClamWin icon in the notification area at the lower, right-hand corner of the screen and selected Open ClamWin, I saw the prompt "You have not yet downloaded Virus Definitions Database. Would you like to download it now?" I chose "Yes" and saw the "Ordinal Not Found" message again.

Open ClamWin

I saw "Completed" in a "ClamWin Free Antivirus: Download Complete" window, but when I closed and reopened ClamWin Free Antivirus, I was again informed that virus definitions had not been downloaded. That occurred even when I right-clicked on the ClamWin icon in the notifications area and chose "Exit" and then restarted ClamWin from the directory in which ClamWin.exe was installed, C:\Program Files\ClamWin\bin\. Double-clicking on freshclam.exe in that directory would produce the "Ordinal Not Found" window.

I tried reinstalling ClamWin and this time was informed that "To complete the installation of ClamWin Free Antivirus, Setup must restart your computer. Would you like to restart now?" I was logged into an administrator account when I updated ClamWin. The user account was also logged in. When I switched to that account prior to rebooting the system, I saw a ClamWin Update window was open with the message "An update of ClamWin Free Antivirus has been released." I now believe that window being open was the cause of the issue I encountered after first installing the update.

ClamWin Update

I closed that window and logged off the user account. After rebooting the system, ClamWin no longer showed the "Ordinal Not Found" error message and I was able to successfully update the antivirus definitions.
