When adware is installed, it loads into memory and stays there, constantly
sending requests to the shareware producer’s website. In return, the shareware
provider sends back ads to display on the user’s screen. These ads are usually
based on buying patterns of the user and what website the user visits. It is by means of these constant transmissions to the shareware company, the connection gets
overloaded and thereby ties down the network.[br]Some adware programs have been known to call other adware programs.Once this is done the second adware program is installed in memory where it takes up necessary memory space. Soon more ads appear on the computer's desktop or the ads appear when certain websites are visited. [br][br]The problem with adware is not just taking up memory and clogging up communications, it also slows the PC down. In many cases the computer takes longer to start up or run processes. [br][br]Another scenario is that the adware program can change the home page of browsers to
that of the shareware provider. This way the user will be exposed to the actual
products, with the idea the user will buy the products listed.
[br][br]To prevent this type of action you need a good anti-adware program like Norton Antiviris. This program will run in the background and destroy all adware programs before they even get installed on the PC. [br]
