請教一個關於Security certificate 的問題

我的計算機不知道什麽時候開始，也不知道是怎麽弄的，鏈接網站總是說要重新續SECURITY CERTIFICATE。搞得很麻煩，不知道這裏哪位朋友能告訴一下怎麽修複這樣的問題。謝謝！

每次一連接就出現象下麵這信息：

Secure Connection Failed
reg.163.com uses an invalid security certificate.

The certificate is not trusted because the issuer certificate has expired.
The certificate will not be valid until 6/24/2008 2:51 AM.

(Error code: sec_error_expired_issuer_certificate)

* This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.

* If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.


Or you can add an exception…
