Sorry if this is the wrong place, I just feel like I am about to tear my hair out.. Whenever I click somewhere on my browser (chrome), there's about a fifty percent chance that a new tab will open, some advertisement for numerous different sites. This is even when I click on the page, or a search bar, or upvote on reddit.. It's driving me insane. I have microsoft security essentials, and I'm currently running it to see if I have anything hidden, but I dont know if it'll find anything. I also use adblock plus, but that isn't working.. Also, there aren't any programs that are in my "add/uninstall" folder, so I don't know how to find them.
I really need some help. Please, if you have any knowledge on removing stuff that does this, please help.
