Adblock still has me confused?

[Steve Dogan]

Is there a difference between adblock & adblock plus? Is there a difference when it says "extensions"? What's that term mean?
Is it free or does it only come with a "free trial buy it after that"? I've been told it's free from adblockplus.org but that's not installing on my IE [I think I have IE 10 & windows 8 ] When I manage to download it, at the end of the process I get a message saying "trial has expired. Please register" At the bottom it says "purchase now" in a little box. And that's on any site.
I've also been told there's a difference between adblock & adblockplus & that 1 is a risky download. True or no?
So now I'm totally lost. Can anyone put all this into "adblock 101"?
It worked the first time for a month free then I got the "trial expired. Please purchase". The 2nd time it was harder to get to work but somehow I got another 30 day thing. Now no matter what site I go on it says trial expired. Other people told me it's free period & indefinitely.

Google chrome allows both adblocks on their internet browser for free.

I have firefox and I just download Adblock Plus as an extension and it takes like 2 minutes to get and that's it.
I don't really know the difference between them both, but I've never experienced anything about having to pay and free trials unless that's something to do with internet explorer, but using it with firefox it's completely simple and completely free.

Using iE (any version) is at best a risk no matter what "extensions" you have.
(Those are a small, add-on 'programs' that compliments the operation of the browser which makes certain functions possible which would not otherwise be available in the 'stock' configuration.)
Allowing all kinds of rubbish back inside has been a continuous problem with iE, such as advertising, 'active scripting', and more.

You would be wise to not use that at all, but get Firefox, or perhaps Chrome.
Either of those can be configured to block all kinds of automatic behavior. Both must be modified beyond the 'stock' settings to attain a solid, safe and ad free state.
