Is this safe?

Is this ad blocker safe? I`m sorry, I know I shouldn't really put this on this forum but I where else to look.

Is this spam?

No, this is not spam. I keep hearing about ad blockers and thought Id try it. Im just worried it`s not safe. If there is another one you would recommend, that would be good too.

I use AdBlockPlus all the time. And I use this forum. So yes, it's safe.
