Geekspeak (NPR) recently shared a report that legitimate sites have more malware than porno sites etc. and the malware is delivered via ads mostly. Does the Chrome extension Adblock Plus "block" ads or just "hide" them? I read reports on it and some state it blocks them and others states it just hide them on the page. Anyone know? And if not, is there an extension for Chrome to blocks ads to prevent malware from ads?
