There is this junk that I ended up getting on my computer when I downloaded an update to Adobe Flash player & shockwave.....somehow they seemed to attach themselves to the download of those updates that we always are in need of. It was called SweetPacks & if I remember, the underlined stuff came at about that same time. Problem was that none of Norton or any of the free antivirus/anti-spyware programs catch it which really irritated me.

Somehow I read something about apps being added in to the browser & the fix was to disable all the apps & start over from scratch. Also you can do a google search on how to get rid of underlined words.....there are many suggestions that come up & you can see if any really fit what you are experiencing & your computer's system setup.

Sorry I'm not a better help. I have had so many of those little irritating things come up on my computer & I don't have the money to take it in to have it repaired every time something wacky happens.....but I also can't remember everything either even though I've tried to print out the instructions I followed, but being unorganized, those notes are all over the place. It is amazing how many things we can find out from googling questions about problems we are experiencing with our computer.

Let us know what you find out because I'm sure that others will experience a similar problem.
