- More Information
Disabled System File Check DLLs are hacked versions of Microsoft dll files related to the system file checker.
Detection of these DLLs indictates that the system file checker has been disabled. Malware families, such as W32/Tilebot variants, are known to patch system file checker dll files in this way.
Some Windows pre-installation tools, such as nLite, are also known to modify these DLLs in certain configurations. Users of these tools may need to authorize the modified DLLs. Information on authorizing potentially unwanted applications can be found in support knowledgebase article 25866.
