Problems with the browser certificate

Lately, the comments box we came several requests regarding a problem with the certificate on google, youtube, facebook, yahoo, twitter and others with SSL (https).
Why do I have problems with certificates?
Most times, the problem has a very simple solution, namely, correct setting of the date of your PC.
Besides the set date wrong, and he has not found a site certificate, but the https page loads, although not certified. If you trust a website that loads the page in https, but it has been certified, you can enter. However, if you do not know the site, I advise entrants.
What's up with the date and certificates?
Certificates are issued by the authority for a certain time. If we set the date on PC outside this range, the certificate is seen as expired. It is therefore important that the PC date and time are set correctly.

If the site is, the certificate must be registered for the If it is done, for example, a DNS poisoning, can occur in the address bar, but you will find it on another site, resembling 100% with, but actually be a phishing site. Compare domain name in the address bar with the certificate for which it was registered. So check the validity of websites working on secure connection (https). Example; DNS poisoning to a website may appear as the bar to write certificate is valid but is not recorded on the, but on the other field.
