I installed 'Myweb search' and 'winamp search' tool bars in my browsers. Now I downloaded some free games from two different websites.But when I tried to install these games I was asked whether to install tool bars of the game sites.I said no and disabled the choice buttons. Later when I tried to play the game alas I see the window saying me to install the tool bars.It quite annoying.How am I to acomodate all these different tool bar in a single browser? Its just similar to blackmailing. The web pages should not force us to install these tool bars.
