Someone is definitely mess up my pc.. When i search for something in google, there is always 4 or more new result in the top page. For example, usually when people type blender and search it on google, the top most result will be the 3d editing program blender. But for me, there is 4 new result on top of it. That said result even appear on the top of the image search. Today i start my pc and the i see a lot of plugins installed on my browser. And even on my windows 10 taskbar there is this "search in google.com" search box that i can't remove. Someone is messing with my pc, and even tried to log on my several account a few times... I already change every password of every important things online, but this things just make me afraid of using my pc.. Can anyone please give me an advise on what to do? Or at least please tell me what the H is going on!
