ComputerWeekly reports that IT executives are increasingly concerned about software that monitors internet usage. In particular, a program called Marketscore - the site for which is registered under the same address as that of comScore Networks - is being decried as spyware for its redirection of web traffic to its own proxy server. The software has all the qualities of proper adware, giving full disclosure for what it does prior to installation and providing for easy removal, but several IT officials say that its promised web acceleration benefits are illusory. comScore has so far declined to answer ComputerWeekly's requests for comment.
