Because of the outdated OS security certificates of the already unprotected Windows computer, these users reported that the contexttool-2.dll malware is able to find and exploit unencrypted TCP/IP network ports that this malware then uses to initiate contact with predesignated remote servers, in order to download more malicious applications unto the system from these remote servers, which are said to be managed by the authors of the contexttool-2.dll malware, and these malicious applications are mostly spyware components and browser hijackers, according to these users. There are also other reports from users stating that their system security tools classify the contexttool-2.dll file as a malicious application associated with variants of the AdWare.Win32.Agent.ckk and AdWare.Win32.Agent.vm applications, which are families of obtrusive adware programs known to be embedded with spyware functionalities.
