Okay, I have something really frustrating going on with this computer. I'm trying to access websites such as yahoo, facebook, etc. and I keep getting this error message saying "Certificate Error: Navigation Blocked.....There's a problem with the website's security certificate." It doesn't come up all the time but more and more it is. Anyone know why and how I can get rid of this problem? I've tried restarting and still it comes up. Like I said, it doesn't come up up all the time when I go to these websites but it's happening more frequently. Any ideas as to why? Thanks in advance.
Update your browser and/or try a new browser - both Mozilla Firefox and Google Chrome are good alternatives to Explorer.
Try going to your system maintenance. Defrag the system, delete temporary files and cookies. Check netwrok access to be sure everything is checked. If all that doesn't work, Can you do a system restore back to before this started happening?
Try using a new browswer or updating your operating system.
