When I try to immunize it says browser open even though i have closed the browser. But it goes ahead and immunizes anyway. i look in task manager and see firefox.exe and end that but there is no further immunization aftwer i end the firefox.exe, so do I need to do that?
On SpyBot Search & Destroy startup, it warns the user if a browser is open. It makes the assumption that the user will heed the warning and close all the browsers.
If Firefox is still in the Task Manager, then it really didn't close. Sometimes, an extension can cause this, especially those added by AVG or Norton.
OK but what i do not understand is it completes the immunization while Firefox is still in the Task Manager. When i end it in task manager and click immunize again there is nothing further being immunized
For the past few updates, there have been no new immunizations included, so immunize has no work to do. That is likely what you are seeing. I always make sure that Firefox closes completely (never had the problem with it staying in the Task Manager), and I always close all browsers.
