There are a number of Internet utilities to help your computer run smoothly when browsing different Web sites. From this week on, we will introduce some useful tools such as banner killers, Internet virtual drives and desktop stuff. There are more and more Web sites with pop-up banners which are so distracting when we browse a site. Sometimes, the Web master wants you to click on the on-line advertisement to track your browsing habits or help them to make money. There are many good ways to do away with them with banner advertisement killer software. Advertising killer ( http://www . buypin.com/akiller.htm) is a small program searching for advertisement pop- ups. Each time a pop-up is discovered, the program closes it. The latest version provides an option to kill pop-ups by their size rather than by their name. The KillAd ( http://wwwwin.wplus . net/pp/fsc/) is a freeware which is easy to use and can be customised for individual needs. When you install it, you have to choose the type of browsers you use or it will not work well on your system. The AdsOff ( http://www.intercantech . com/) is a useful tool to kill the pop-ups and banner advertisement, and is only 1.4mb in size. You can only try it out free for 30 days and it needs registration afterwards.
