can you tell me why my browser is functioning so weirdly? i use chrome all the time, but i have noticed that this happens on other internet browsers as well. i have noticed that whenever i click on any spot on the internet, a new pop-up window appears with an ad from or other never-heard-of pages. what’s the matter? these pages urge to install software updates, for example, java updates. i am sure i don’t need another java update. help me to fix this problem, please. my computer works slow as hell, too
