Frequently occurring are file sizes such as 24,576 bytes (72% of all these files), 50,688 bytes as well as 5 other variants.
It is no part of Microsoft Windows. This DLG program does not appear as a visible window, but only in Task Manager. When Windows starts, this process is automatically started at the same time (Registry: MACHINE\User Shell Folders, MACHINE\Run, User Shell Folders). For this reason, 45% 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 DLG.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.

What do other computer users say about DLG?

Came with Dell laptop to support Broadcom modem. It checks on boot and periodically if you are plugged into a digital PBX plug instead of an analog modem plug. I presume that it is attempting to protect itself as this situation used to destroy modem cards years ago. I think that most modern modems have some sort of protection now.
