Problem of many words automatically hyperlinked all over pages

Go to your Control Panel and click 'Uninstall Programs". Go through the list of programs installed in your computer and uninstall any that seem unfamiliar by right clicking. The advertisements show up when a program is installed in your computer; when you visit certain unreliable websites, programs that you may not want download automatically.

You might also want to do a scan of your computer to check for any potential viruses if you find any downloaded programs. :)

Edit: Another thing you should check is what add-ons are installed on your browser. Let me know what browser you use and I can tell you how to check your add-ons. Sometimes unwanted add-ons get enabled for your browser. [Which also means there's an unwanted program downloaded in your computer most likely].

Thanks so much for the detailed help, guys. :))

I checked, there's nothing new, and the problem is only on I-F. :(

And in addition to random words automatically being hyperlinked with blue colour and double-colouring (if the mouse accidentally goes near, a green double-circle starts spinning on it),
there's a sudden number of huge advertisement pop-ups that aren't even prevented by the popup-blocker activated.

When net is slow, then having a dozen full-page ads pop-ups for every page forces to go to much less pages.

Really hoping this is a glitch which can be sorted, because otherwise going to have to continue as currently - which is a few pages everyday. :(
