- You see unusual error messages.
- You see distorted menus and dialog boxes.
- There is a double extension on an attachment that you recently opened, such as a .jpg, .vbs, .gif, or .exe. extension.
- An antivirus program is disabled for no reason. Additionally, the antivirus program cannot be restarted.
- An antivirus program cannot be installed on the computer, or the antivirus program will not run.
- New icons appear on the desktop that you did not put there, or the icons are not associated with any recently installed programs.
