Security settings with ie8

Hello to all computer wizards on this site,


I have been currently experiencing annoying security windows or pop ups on websites that I trust and daily visit which involve
error details explaining that webpage content will not be delivered using a secured http connection, content will be blocked due to unvalid security certificate, and a few more security warning boxes.

My computer has Windows xp professional, o.s. version 5.1.2600, service pk 3.0, ie version 8.0.6001.18702,microsoft directx version 4.09.00.904 , ie8.

I have so many other problems with this old pc but I if anybody can help me in this matter or give me some other tips than what my pc troubleshooting has done for me much would be appreciated.
I also would like to know what boxes should be or not be checked in the security settings internet options.


Thank you,

Have a great day!

 

I have suddenly began to experience a similar problem although all of my 'Security Warning' pop ups are the same

Displays the message "Do you want to view only the webpage content that was delivered securely? This webpage contains content that will not be delivered securely using a secure HTTPS connection, which could compromise the security of the entire webpage."
Yes or No has to be clicked before any other action can be completed.
If you click yes, it displays the page without the graphics, no shows the pictures!
Totally new, mad and unnecessary and it is driving me crazy!

Any ideas on how to stop this ridiculous Security warning that pops up with any page change (even the Browser backpage).
