What is Run_Dregol?

Identified as a version of the CMI/ConvertAd family of malware ad-injectors, this adware which is typically bundled with third-party applications in unwanted software bundles will hijack the user's browser (Internet Explorer, Chrome and Firefox) and display unwanted ads. When running, the process will monitor and capture internet traffic and insert advertisements over existing ads or by placing new ads in white space. In either case, these ads are low in quality and even dangerous in many cases as they might be infected with malware javascript (malvertising). In addition to displaying these unwanted ads, the software runs as startup in the local application data via a registry run key and sends commands to the controlling server to request new ads based on the context of what the user is doing. This action will also report back to the server what domains the user visits, what URLs they enter as well as in some cases might send back cookies. If the sites visited are not SSL encrypted passwords and usernames might be sent to the server compromising the privacy and security of the user.


Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. When installed, it will add a context menu handler to the Windows shell in order to provide quick access to the program. The main program executable is IVI_VISA_COM_CleanupUtility.exe. Typically most users end up uninstalling this just after a few days. The software installer includes 104 files and is usually about 1.01 MB (1,062,724 bytes). mcdatupdate.dll is the automatic update component of the software designed to download and apply new updates should new versions be released.
