The name scareware describes what this malware does. Most often, it takes the form of a window on your screen telling you that faults or viruses have been detected and you must buy the software it offers to fix these "problems". Often, the messages are designed to look like they come from your Windows system in the hope you will think they are genuine. In many cases, access to the Internet generally, or at least access to removal instruction websites, will be blocked so that you can't get help to remove the infection. We can do the removal properly for you.
