Don’t panic if you’ve found this browser hijacker on your computer because there is no serious reason for concern. Operative Device may indeed behave in a very invasive way but this program is far from real computer viruses and malware such as ransomware or Trojans. Browser hijackers, in general, are not identified as computer threats. Nonetheless, security analysts consider them as potentially unwanted for a variety of reasons.

For starters, the random page redirects that such software applications appear to cause inside the infected web browser are a main reason for concern. Such uncontrolled redirects might sometimes take you to a risky web location where real security hazards including the aforementioned Trojans and even ransomware viruses may lurk.

In addition to that, a hijackers like Operative Device, Common OptimizationSearch Baron and Search Marquis may change the browser’s homepage with a different one, replace the default search engine, install some new toolbars, and even randomly open new tabs without any actions from your side. Such services are potentially undesirable and may present a long-term security risk to your Mac.

Therefore, we highly recommend uninstalling Operative Device and its changes to all the users who are having trouble with this software. Below, we have even published a removal guide with instructions on how to remove all the unwanted components, as well as a trusted automatic removal tool for self-help.
