I use facebook, youtube, the whole internet and never have a issue, I also don't just random click stuff either without reading what your clicking more so on install of programs as like was said they love to piggy back installs, like yuck mcaffee from java updates. Don't just keep clicking ok on installs each time a ok prompt opens look it don't click ok. I use to use avast but was told microsoft security essentails was better, and since using it I naver had any issues, I also use advance system care to clean my system up and so far has been doing great, it even starts to give you a frowny face when you need to run it. I have also malware bytes but don't run it that often as most sites I visit are ones I go to all the time, but when I start going to new sites I update malware bytes and run it. I also have spybot search and destroy I run once in a while.
