Hack web browser and disable antivirus by create certificate error( The site's security certificate has expired!) by changing system date

1. very first make sure your PC has SSL AND TSL enable.

                 To do that:--

• Open your internet explorer 
• Goto tool option>>>setting>>advance>>security 
• And mark use SSL 3.0 and Use TSL 1.0/1.1/1.2(any)
• Or simply click on restore advanced setting. (see pic)

Now check the validity period of certificate of any https (Hypertext Transfer Protocol Secure) 

       in this case I am taking Facebook 

1. click on the lock sign just before https 
2. goto connection
3. click on certification information (see the pic)

Now here you can get validity period (which is upto Aug of 2015 in picture)

You can see in picture below my system time is between validity period

Now here is something new

I have just changed the system time as 1st Dec 2015 (out of validity period) and restart my browser 

look the picture below 

OOPS   I can't access Facebook (read the marked two line carefully )

                  My antivirus also got expired  (So Sad)

Thank God I have a trick to get rid out of this 

Only I have to take my Laptop in current date and restart the browser!!!!!!!!!!!!!

Is it kind of Hacking  must reply!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
