AdFender is a straightforward ad blocker which works with just about any browser, and requires the minimum of setup - just install the program, restart any open browsers and you should find ads in web pages are blocked immediately.

Does it work? Yes, mostly. We noticed a significant difference immediately, with the enormous majority of ads (not quite all, but near enough that you won't care) disappearing, all without you having to do anything at all. This speeds up your browsing by reducing the amount of data you're downloading, too, and hovering a mouse cursor over the AdFender system tray icon will show you a tooltip with the total amount you've saved too far.

There's also the potential for problems. AdFender works as a content filter, stripping out anything which looks like an ad, and we've seen this effectively break sites before, very occasionally.

Still, even if you do have issues, it's possible to create custom filters to block ads on some sites, and not others. That's suddenly not looking quite as straightforward, of course, but the option is there if you need it.

Version 2.26 (Changelog):

Fixed issue with 404 errors when using IE 11 on Windows 10

AdFender blocks a lot of ads immediately. It can also prevent some sites from working, but this seems a very rare problem in the current builds, and if you're affected then you can just turn the program off for any affected sites.
