Coantivirus.com Description:

If you have ever seen a random browser hijacker in action, Coantivirus.com (or Coantivirus.microsoft.com) is just the case. It hacks your browser and makes you hit a bad website that compels you to buy rogue anti-spyware. The malware program being promoted by Coantivirus.com is called Antivirus System Pro, and it’s a pretty nasty one. Coantivirus.com changes some system parameters such as Hosts file and browser settings without asking for user permission. Having completed that, Coantivirus.com causes you to find your web-surfing activities ending up on a fraudulent website that tells you anything but the truth. Coantivirus.com claims you’ve got insecure internet activity going on and insists on your registering Antivirus System PRO licensed software (which is a cyber pest at its worst). Once you get redirected to Coantivirus.com, you should be able to exit the web page – but it’s going to keep coming back and get yet more annoying as the hijacker proceeds. The only way to stop Coantivirus.com from playing havoc with your internet surfing is removing the hijacker that settled down inside your computer system.
