I'm trying to fix a classmates Windows 7 laptop that she desperately needs for school. I'm having a hard time figuring out what is going on with her internet explorer. Every time I try and load a page ( Google, Yahoo etc..) I get a error that there is a problem with the websites security certificate. Now, I can click "continue, not recommended" and usually get through but some sites, like the college home page, just come up as web page not available. I've tried turning off the firewall but that has not worked. Any suggestions?
