whenever i open internet explorer , security alert box apears, told me that security sertificate has expired?

Question

almost in every page i open , tell me , do you want to proceed? how could i get rid from this bothering box ??

Answer 1

Ensure that you have installed the MIT Certification Authority (CA) certificate for IE. This will get rid of the alert dialog box saying that the 'The security certificate was issued by a company you have not chosen to trust.' Instructions for installing the CA are provided at http://web.mit.edu/ist/help/ie/.

Let IE remember your personal certificate password. When you install your personal certificate for IE, MIT recommends that you set its security level to "High." This requires you to set up a password for the certificate. Once the password is set, you are prompted to enter it each time you access a secure Web site at MIT. You can change this so that IE will only prompt you once per session, if you select the "remember password" checkbox the first time you are prompted. IE will not ask for the password again until you Exit and re-open the browser.
If you choose to not use a password to use protect your personal certificate, be sure to never leave your machine unattended. Either logout or lock the screen, otherwise someone will be able to impersonate you by using your certificate. For Window 9x/Me machines there is no safe way to lock the system, so you really need to use a password to protect your certificate.


If you have only one certificate installed on your PC, tell Internet Explorer not to prompt you for which certificate to use when accessing a certificate protected Web site. To do this, follow these steps:
From IE's Tools menu, choose Internet Options.
Click the Security tab.
Click the Custom Level button.
Locate the setting Don't prompt for client certificate selection when no certificates or only one certificate exists, and click the Enable radio button

Answer 2

Nah, check your date and time settings. Theres a good chance that every site you go to hasn't had its certificate expire at the same time, and just for your computer. The certificate is valid between certain dates, and if your Pcs clock is wrong, you'll get invalid warnings from every site you go to.
If you change the time, and after a reboot or shutdown the time goes back wrong, get the CMOS battery changed, should be a few bucks at a mom and pop store or do it yourself.

Answer 3

Save yourself the headache and use a different browser.

United States Computer Emergency Readiness Team:
"There are a number of significant vulnerabilities in technologies related to the IE domain/zone...It is possible to reduce exposure to these vulnerabilities by using a different web browser"

Answer 4

Too late, but you should always backup your system before downloading anything. Next time use Restore which you can find on your computer with a Search. If you are getting virus alerts can't you quarantine the 'virus'?

Answer 5

It may be because your internet security level is too high, or not high enough. If you haven't checked that.... go to control panel and then to internet options then to security settings. Hope this helps!!!
