Re: Rivarts.A please help
Downloader.FHO is a Trojan that downloads from a certain web page another Trojan detected as Rivarts.A to the affected computer.
Additionally, Downloader.FHO is able to update itself by connecting to the Internet.
Downloader.FHO does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
