10 points Why does internet connection keep switching from secure to insecure?

[Jennifer P]

This has been happening to me alot on firefox and google chrome. My connection keeps changing from secured to unsecured. I would go on youtube (padlock sign) and search for something. Sometimes when I click the back button or on some video the connection changes to padlock sign with a triangle with an exclamation point. The same thing also happens when I search something on google. I search for something (secured padlock sign), click on a link (secured padlock sign), click on back button to google search (padlock sign with a triangle exclamation point). I scanned my computer and nothing seems to be wrong with it. I'm not really good with technical stuff. When I usually search for something on google or anything images usually don't show up and I also have adblocker.
Whenever I click the back button it automatically switches to "not fully encrypted"

It sounds like you may have some malware that is attempting to show insecure content on secure pages.

I would recommend downloading Malwarebytes product and try scanning your computer with that. Also, disable any "toolbars" you may have installed in your browser add-ons.

I bet you have some Ad-ware that is trying to show you inline content in an insecure fashion.

When you go to a site, look at the URL (web address) to be sure that it should be secure. To do this, look at the very beginning of the address. If it begins with "http", then this is an unsecure site, if it begins with "https", then it is a secure site, and the padlock should be closed.

Not all sites are secure, or need to be. The only time you need to have a secure connection is when you are attempting to pass information like credit card or bank information to buy something. If you are simply browsing a site, the need for a secure link is not necessary, but some sites do provide it anyway.

I hope this helps you.

This is because your browser starts out connected to secure servers (denoted by 'https' URL prefix), but when you start moving around, it will display items not coming from those servers, but from 'regular' servers.
This condition is normally associated with advertising, but many advertisers are moving their own delivery methods to 'https' in order to get around browsers set to "display secure content only"...and thus get their ads displayed.

The best approach is to block 3rd party advertising, and remove the uncertainty about this kind of content even being allowed in the first place.
Effective control of returning assets takes several mod's, plus which browser is used.

Chrome is here (although it's getting harder to get this to work as desired): http://ca.answers.yahoo.com/question/ind...409AAZGnI6

'Secure' servers should be used whenever possible. This assures that the content you are getting is exactly as it is on their server, and has not been manipulated during transit (by a "man in the middle"): that could lead to fake websites in control of the bad guys.

"HTTPS Everywhere" add-on assures you connect to those (if they are available), and "Certificate Patrol" will interrupt automatic acceptance of 'Certificates' and give you the power to accept or reject the Certificate. Both are for Firefox.
