Problem using Chrome and IE. Security issue?

[G2C2C]

When I'm using Google Chrome some words on the page come up looking like a link and when I hover over them a little box appears over the word with advertisements in it.

I don't mean words the side of the page, I mean random words within the text of paragraphs etc. For example, after I post this and go back into it later, any one of these words I'm typing could come up as a link with advert.

Can I turn this off, and do you think it's a security problem. Different people use the PC at different times so it's hard to keep track of who is doing what.

On Internet Explorer, now everytime that I use it, there is a red line through the https on the address bar and I keep getting prompted about whether or not I want to view only the page parts sent securely.

Can anyone help with these problems?

It MAY be this problem?, but you need to check with better techies than me as to the root cause.

As IE is reporting that there is a security issue with the web pages visited by both Chrome & IE, I'd be leaning to issue as above. ☺
