This application blocks pornographic images from loading on your system although some lewd material still seeps through its mechanisms. PicBlocks doesn't use keywords to block URLs based on content so parents be warned: offensive terms and text are viewable. PicBlock's standard interface allows you to adjust its restriction levels from mild to normal to strict, but strangely enough no clarification is given as to what each level permits and prohibits. You can choose to display a pop-up notification from the system tray, a prompt, or a simple blink from the tray each time a site with porn images is loading. A hot-key combo can be used to unblock Web sites you'd like to gain full access to and PicBlock will automatically place the URL on your safe list for future visits. While some images were blurred out of sight, it didn't obscure every vulgar image on several Web pages, even at its strictest configuration during testing. Although free, we can't readily recommend this program since offensive images and text may still be viewable by children.
