Internet ads are not only annoying, but dangerous. Blocking ads to protect your computer just makes sense. Nowadays, I consider an ad-blocker as your second layer of protection, after your antivirus.
There are many ad-blocking extensions out there, but things work best if you install only one at a time. AdBlockPlus is freely available for almost every computer-based browser and for limited use on smartphones:
After you install AdBlockPlus, it’s important that you tweak its settings for maximum protection. Find the ABP stop sign icon in the corner of your browser, and right-click it. Go into its Options page, check all of the boxes under Free Features, and clear the checkbox for Show Acceptable Ads.
This should suppress most ads on websites you visit. Now, your web-surfing may be more pleasant, faster and safer!
