PageNotFound.co virus by some company called LavaSoft

I recently installed a toolbar for my laptop, for a program called AdAware. Ever since I did, my browser has been hijaaked and constantly takes me to a site called PageNotFound.co. The company that has spread this virus is called LavaSoft, so think twice about installing their products. Does anybody know anything about this company? /biggrin.png' class='bbc_emoticon' alt=':D' />
