Multiple Programs – FNTCACHE.DAT, FNTCACHE.DLL

Fntcache.dat, gdifontcache.dat, and mlfcache.dat appear to install with Windows 2000 or later and Microsoft Office 97 or later and with some versions of the Adobe PDF software. These files will generally appear in your Windows\System or System32 folder. They may be reference when deleting font cache and media file cache files. If you use WinPatrol 10.x or later, you may see them listed in your Hidden Files.

Fntcache.dll installs with the W32/Kraze.dr virus. This virus runs on system startup. It attempts to access the Internet to download and install other malicious files. You'll find more information at http://vil.nai.com/vil/content/v_140044.htm. We'd recommend removing this file using WinPatrol. First, kill it under Active Tasks then remove it from your Startup Programs. If running WinPatrol 8.x or later, right click the file then select "Delete file on Reboot". Finally, reboot your system.
