    thanks SO much! I just got this new laptop from my dad and its pretty old and simple so when I have a virus its easy to get off by going to the control panel and all that, but this time i didn’t have a CLUE what to do. At first I thought this was useless but JUST A WARNING! sometimes it won’t say the advertising thing, it will say “Instant Dictionary” if you use Google Chrome and click on the “customize and control Google Chrome” button, and then go to tools, and extensions. For me, I only had 2 things on there. “Google Docs” and “Instant Dictionary”. I disabled both of them and when i reloading all my pages it was completely fixed. Again Thank You!
