You know those ads that take over your entire screen? Or the ones that intrusively play music, alerting everyone around you that you've visited a website that is probably not work-related? How about those ads that leave behind tracking cookies so they can monitor your internet surfing behavior? These are the ads that make you scared to surf the internet. Fortunately, you can avoid them.
Ad blockers are among the most popular browser extensions around. But if you use several browsers on several PCs, keeping everything in sync and installing all those plug-ins can be a pain, especially when you could be blocking ads at a higher level.
It's not hard to block ads long before they reach your browser, you just need to set up an IP-blocking list (the same technology your browser-based blocker is using) either on your PC or through your router.
