You may never know your computer is infected
Think about it. If a cyber criminal is monitoring your computer to steal your passwords, they do NOT want you to know.
If you ever found out your computer was infected, you would do something about it right away. This is why it is in the best interest for cyber criminals to disable your anti-virus software, automatic updates, and other protection measures quietly and effectively. That way, you keep using your computer “business as usual” and have no idea your computer is “owned” by a criminal.
I am thrilled to see articles about IT security issues so much in the news. Maybe everyone will take this threat even more seriously and, together, we can hinder the spread of the infections.
