I didn't download anything to cause this, so I don't know why it has started.
A few days ago I noticed a large Highlighter Pen logo up top in my browser.
I have no idea how it got there.
Then I noticed there are a lot of words underlined with a yellow line on everything I open!
Even in these posts.
Whenever I accidentally mouse over a word that is underlined a giant Wikipedia window opens with information about the underlined word
Also, since yesterday it takes up to 30 seconds for my lappy to do anything. Whatever I click on takes up to 30 seconds to do.
Today I have had enough of this annoying crap so I googled 'Remove Wikipedia Highlighter' but could not find anything about it.
After shutting the search page I notice that the Highlighter logo has dissappeared but it still opens a wiki window on the underlined words!
Then I noticed my whole browser looks diferent
The normal Firefox highlighter logo has also vanished, and the Google Search text box is gone too.
No, I didn't close them, I checked.
The only thing I have done different today is run AVG virus check and it came out clear.
Anyone able to help me please.
