I haven't seen a pop up since I installed ZoneAlarm Pro a few years ago. its got a pop-up and banner-ad blocker.
I absolutely hate those Annoying Flash Ads, in particular the ones with sound and seizure inducing blinking lights!/ubbthreads/images/graemlins/mad.gif /ubbthreads/images/graemlins/mad.gif /ubbthreads/images/graemlins/mad.gif /ubbthreads/images/graemlins/mad.gif
I looked all over the web for a tool to just turn off flash and to stop bugging me to install it.
"No! Flash" its a 64k freeware app for MS-Windows(all-versions) it blocks Scripts (Popup Ads, Animated Ads...), Flash(Macromedia Shockwave Flash v6), Images, Videos, Animations (GIF Animation), Sounds.
And since everyone is giving there preference for web browsers here is mine,
SlimBrowser, it also has pop-up blocker and lots of other stuff. Best of all its freeware.
