However, browser hijackers are a type of software that is not malicious and cannot be held responsible for criminal activities similar to those that threats like ransomware, spyware or Trojans can initiate. Yet its presence in the system may affect popular browsers like Chrome, Firefox, Edge and others and create a lot of irritation and browsing disturbance as well as lead to some annoying performance issues such as screen freezing, browser unresponsiveness, and sudden crashes during your browsing sessions.
