*facepalm* Same problem as the above several people. "FixUpdate.exe" reports that nothing needs fixing, but I still can't get updates, and new to me, using the Add/Remove button in the Windows XP "Add/Remove Programs" settings returns an "avast! Setup Fatal Error". As such, I've sent you an e-mail with the requested files in a ZIP file. (The file is named "JDC_avastVPXes.zip".) Hopefully, we can get this second snag straightened out!
