Strange things happening....

[Mithlomwen]

So I'm not sure where or how I picked whatever this thing is that's taken over my computer. 

I have this annoying add thing, that when I click on sites like Ebay, or Amazon....virtually any site that sells products of some sort, I get these annoying little pop up adds that I can't make go away.  I have ad block on my computer but it doesn't seem to stop those. 

Also, when I view web pages (even here on E) random words or phrases will be highlighted green, and if I hover my mouse over the word I get links for job searches and things of that sort.  o_O 

Any idea how to get rid of these things?

In my experience that usually means that you managed to inadvertently install an extension to your browser. Most of these can be easily disabled, but it's a slightly different procedure depending on your browser. In Chrome, for instance, you go to Tools>Extensions. Then find the ones listed that you didn't intentionally install and remove them.

Aha!  *happydance*  I found what it was.  ;D

Thank you so much!

Some of the little buggers stealth-install, but I've made it a point to read every check-box when installing updates to things like Flash, Java, drivers, etc.  I've caught a few trying to sneak the Ask toolbar or various other undesired tidbits in as 'extras'.
