ad tag lines in post

[u133066]

I have noticed on the board that I administer a sinister and intrusive happening. When certain words are used in a topic post (software, post, register) automatic advert boxes pop up. I see this is also happening on this community site.
Is there a way to stop this intrusion (switch, flag, check box)? or are we doomed to a life of ad spammers everywhere we go.
thank you

I see this is also happening on this community site.

It is? Where's that, then?

I can't say that I've seen any.

Check front page of forum "news and updates, the word 'software'

Then it's something installed on your computer - this site has no such ads.

Nope. I'm not getting anything on either of these pages.

OK I can accept that, I am using Chrome at the moment wilt try with other browsers and see if it is the problem.
Thank you

Seems to me like you probably need to check your browser for installed extensions - and maybe remove some of them, plus check for other malware and viruses.

You are probably correct.
I have checked Explorer and Firefox and Chrome - Explorer is ok no tags, both Firefox and Chrome have ad tags. Will have to go deep into the extensions etc.
ps. I have reset my extensions in both Firefox and Chrome result - ad tags disapeared
Thanks for your comments and suggestions  it is appreciated.
