When I try to enter any website, I get a screen that says: there is a problem with this website's security certificate. These are websites I use all the time, e.g. AOL. It can't be a problem with every website. It has to be a problem with my computer settings.mthis happened once before and I had to change the date and time. I tried that this time, too, but this time, it didn't do the trick.many suggestions?
