These users also claim that the contenttool.dll malware is activated by one of its executable component processes that is said to be capable of automatically initializing during system startup because of certain keys and entries that this executable process is said to be capable of creating and inserting into the unsecured Windows System Registry upon its successful placement and activation in the unprotected Windows-based computer.

Other users reported that their anti-malware applications classify the contenttool.dll file as a malicious application associated with the ADW_SEARCHTOOL.I program, which is another family of obtrusive adware items with spyware functionalities.
