Okay. I have tried synchronizing my time with time.is , uninstalling Kaspersky, clearing my Cookies and Cache, disabling IPV6 in about:config , reinstalling, refreshing, uninstalling conflicting and non-updated addons and extensions, deleting the db file, setting the settings to "No Proxy", disabling Windows Firewall...

...And this is still happening:

" The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported."

"(Error code: sec_error_unknown_issuer)"

(Additional Note: Google only works if http://www.google.com/?gws_rd=ssl is specifically typed in without the S.)

hi LexDrgn, in order to know what's going on we probably need more information about the failing issuer of the certificate. please proceed like this: enter chrome://pippki/content/exceptionDialog.xul into the location bar, and in the page that opens, set the server location to "https://www.google.com" in order to retrieve and view the certificate. then please report back with the data of the issued by section of the certificate viewer. thank you!

yeah, this might happen for user accounts where parental controls are switched on - please see http://support.microsoft.com/kb/2965142/en-us#2 for more information on how to resolve this.
