For some time I have been receiving the dialog box containing "Security Alert 'Revocation information for the security certificate for this site is not available. Do you want to proceed? [Yes] [No] [View certificate]' ." I know that many, if not all, of the sites are OK as I have used them multiple times in the past.
I have tried various "fixes" found by Googling "revocation information" and nothing fixes the problem--what ever it is.
When I try to do various updates, not related to this problem, I am not allow to download the updates because of a security problem.
Any suggestions for a computer challenged user? Thanks.
