What you should know about dfsvc.exe ClickOnce

dfsvc.exe is not a Windows system file and is known to frequently cause computer problems. Dfsvc.exe is found in a subdirectory of C:\Windows. Frequently occurring are file sizes such as 5,120 bytes (37% of all these files), 23,192 bytes as well as 6 other variants.
This particular software does not appear as a visible window, but only in Task Manager. The file is no part of Microsoft Windows. The original file has a digital certificate (see its file properties). dfsvc.exe appears to be a file that was compressed by an EXE-Packer. This technique is often used by trojans to keep the file size small and also hamper debugging efforts. However, this in itself is not sufficient reason to presume malicious intent, since even well-intentioned, professional software producers take advantage of compressed files. For this reason, 20% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.

If you see this file on your hard drive or in Windows Task Manager, please make sure that it is not a malicious variant. It's a fact that many trojans try to cloak their true identity by calling themselves dfsvc.exe. With the above information or by using tools like Security Task Manager you can determine if, in your case, the file is an undesirable variant.

How to tell if dfsvc.exe (ClickOnce) was uninstalled cleanly

After uninstalling, restart your computer. Then start Windows Explorer and see if there is still a folder with the name of the software under C:\Program Files. Be sure to check the Registry as well for remnants of ClickOnce. To do this, start "Regedit", then look under "HKEY_LOCAL_MACHINE" > "Software" for ClickOnce or the name of the producer. Always keep in mind that only a computer professional should ever directly delete entries in the Windows Registry.

What to do if a program does not uninstall

The easiest way to remove any kind of software cleanly and accurately is to use an uninstaller tool. Because the uninstaller automatically creates a backup, there is no risk of anything going wrong.

Last but not least

If Windows not working quite right for you, or if startup is taking a long time, or dfsvc.exe is causing problems for you, a good Windows diagnostic tool may very well help. This is especially effective when it comes to older computers that have accumulated vast quantities of "garbage data" as the result of many software installs and uninstalls.
