I have SSL protocol / https checking enabled. (Did that while testing the eicar test site). Since then I am unable to check for updates in Firefox 3.5.2. To be honest I'm not sure how to use SSL checking and whether I even need to have it on. So any / all advice and guidance would be welcome. I only mention the following as it adds to my confusion on this subject: How come a certain AV tool starting with the letter 'K' will detect the eicar https test files but not cause problems elsewhere? What is different about NOD32 https checking? - I was hoping NOD32 would achieve the same result. Thanks - trialling NOD32 AV Version 4.
