dfrgfat.exe is a process which belongs to Microsoft's Disk Defragmenter FAT File System Module. However, I have also read that Diskeeper Disk Defragmenter uses a file with that same name.Determining whether a file is malware or a legitimate process usually depends on thelocation (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file. However, it then places itself in a different location (folder) than where the legitimate file resides and runs from there. Another technique is for the process to alter the registry and add itself as a Startup program or service so that it can run automatically each time the computer is booted. Keep in mind that a legitimate file can also be infected by polymorphic file infectors.Anytime you come across a suspicious file or one that you do not recognize, search the name using Google. If you cannot find any information about, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to one of the following online services that analyzes suspicious files:http://virusscan.jotti.org/http://www.virustotal.com/xhtml/index_en.htmlhttp://www.virscan.org/Microsoft MVP - Windows Security 2007-2010
