Deleted Security Certificates

Greetings all,

I had been having some sluggish responsiveness from Chrome and decided to reinstall the browser. I went through the uninstall then downloaded Chrome again from the internet and re-installed. One problem, I started getting SSL errors on a site that was working prior to the re-install.

I thought that if I deleted my security certificates they would repopulate as I went back to the sites where they were issued so I went in and deleted all of my certificates. Not a real good move.

Is there some way to get them back? Or what do I need to do in order to be able to use this computer again on the internet?

Thanks

Jake
