我正在尝试浏览互联网，但对于我键入或输入的任何链接，我都会收到以下消息：
This Connection is Untrusted
You have asked Firefox to connect securely to accounts.google.com, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
单击选项后Technical Details，我收到以下消息：
accounts.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. The certificate will not be valid until 25-02-2014 20:49. The current time is 22-08-2009 14:42. (Error code: sec_error_expired_issuer_certificate)
我不知道是不是因为某种病毒或其他原因。但我每次访问任何网站时都会弹出证书问题，这让我快要发火了。有人能帮我吗？是不是因为某种病毒跟踪了我的浏览或窃取了 cookie？谢谢。

确保日期和时间设置正确。计算机和服务器的时钟同步对于证书的正常运行非常重要。
