Seems you have something else running int he background doing that. Do you have a spell checker on ? Or maybe it's advertising malware. Give us a few examples.
Must admit, I find it particularly annoying when prompted to use an American spelling of a word.
I wonder if there is a preference somewhere you can alter to English spelling?
Flavour is an example, I do NOT want to spell it flavor.
When I hover my mouse over the green words, a square pops up asking me to take a survey for Better ads, I've scanned it 2x with malwarebytes and deactivated these ads previously, am stumped.
Oh I think I've sorted it, went into control panel, and saw something called better surf which I haven't seen before so uninstalled it and all appears OK now, fingers crossed! Thank you all.
netibiza, I had the same problem up to yesterday, it was so annoying, I noticed on every new tab a name of a website showed up, I use chrome and windows Vista, first I checked for add ons in settings then went to control Panel and uninstall program (with my fingers crossed) and uninstalled the website I just noticed, I've not had blue underlined words since, they were so annoying - I'm so happy it wasn't just me had the problem.
Ducksie, at first I didn't really notice and then I was getting advert gaps between answers which I knew weren't right, took me a while but hopefully it's sorted now.
mine was the same, I knew it wasn't normal, so I thought, I'll try fix it myself, if not, I'll get onto someone here, I knew there'd be an expert about if what I did was not working, I forgot to mention, I did a full scan on my computer after, I use Microsoft essentials (MSE) so it's all cleared up now thankfully
I was just thinking there netibiza, had I asked for help with my problem it may have solved yours earlier as obviously it wasn't a spellcheck problem. I'm so glad you brought it to light
