I am afraid to install the portable version since i installed xampp from this site and got a Trojan horse.
This application was inspired by linux's virtual desktop. It helps you make multiple desktops in windows.
it is possible, and has been done twice I believe.

Although none of the versions here are capable of handling plugins, they should work fine.
also, in case someone else didn't do it, welcome to PortableApps.com!
But there’s no sense crying over every mistake,
You just keep on trying till you run out of cake.
What antivirus app do you use? Your trojan is probably a false positive. If you recieve alerts like this from PortableApps you should re-scan the file on something like VirusTotal. If the result is clean on the online scanner, then perhaps you could report the alert as a false positive.
This app is excellent, I'd like to see it on the application list. A must have for anyone who multi tasks. I'm using the portable version available from here: http://virtuawin.sourceforge.net/downloads.php
