In brief Virus writers have developed a Trojan downloader attack that poses as an offer for the latest edition of Google's Toolbar, the popular search tool. Spam messages that began circulating on Wednesday attempt to trick users into visiting a maliciously constructed website, disguised to resemble the genuine Google Toolbar site, reports UK-based net security firm SurfControl.

Users who accept a offer to download "Google Toolbar" software from the bogus site will find themselves installing a Trojan which turns their machines into zombie clients, controlled by hackers. ®
