Final note

Malware often leaves traces behind. Even when the malware is remove by your antivirus program. However, errors like “The specific module could not be found” are not always caused by malware. An upgrade of Windows 10 or uninstallation of 3rd party software may also leave traces. A great example is Logitechs logilda.dll
