Windows Antivirus Pro is a rogue anti-virus program and a ransomware that does not allow you to run any programs on your computer. When Windows Antivirus Pro is installed it is configured to run every time Windows starts. Once running it will automatically scan your computer and then list a variety of infections that you cannot attempt to remove until you purchase the program. This program also acts as ransomware because while it is running it will state that almost any program you try to execute is an infection and not allow you to run it. This makes it hard to run any legitimate anti-malware programs until you end the Windows Antivirus Pro processes or purchase it.
While Windows Antivirus Pro is running you will also see numerous security alerts and hijacks appear while using your computer. A summary of the types of alerts you will see are:
- The following message will be shown when you try to run almost any application:
Running of application is impossible. The file C:\Windows\Notepad.exe is infected. Please activate your antivirus program.
- Security alerts, or Infiltration alerts, falsely stating that your computer
is under attack or that a security risk has been found. Examples of messages
you will see are:
