The immunization feature protects your system against any new malicious ActiveX while you are surfing the internet.

Click on the Immunization link on the Main Status & Summary screen to activate immunization. If your computer is not immunized or Immunizer is switched off, there is an increased risk of your computer being infected by one of these malicious ActiveX objects so we recommend that unless you are an advanced use and know what you are doing, you have immunization switched on.
