Highlights:
The information about what ads AntiPopUp has blocked, including the URL of referring sites and the destination URL of the ads
Lowlights:
It is necessary to check the 'Auto Start' option for AntiPopUp to run automatically. Out of its depth with floating Flash ads.
BotSpot says:
AntiPopUp for IE is an ideal mid-range tool. Easy to set up, tough on pop ups, it provides just enough information to let you see what a good job it is doing, without making your head spin in a whirl of options. The small file size and low price make it a good choice in the war against pop ups.
