Uhhmmm... my laptop. How do I get rid of it? Sounds like having the herp and not knowing it!What are you making posts with that causes there to be commercial links embedded? I just removed link from the words "Play doh" and "valve spring" from your post above. If it's a computer then you have maleware/adware. If it's a free browser of some sort on a mobile device, then it's not on the up and up either. The one for play doh was a link to Amazon and the other was a link to ****.
Edit* doing a scan now...
