VIRUSES AND MALWARE

Since G.ho.st is flash based your G.ho.st VC does not execute files locally, it interprets your files in the browser, and that way it cannot actually get malware. Your files may have a virus or malware in them but as long as you use them on G.ho.st you have nothing to worry about.

Since the files are never executed locally nor on the server end, infected files cannot infect any other files on your G.ho.st drive or any other users G.ho.st drives

If you download a file from g.ho.st that has malware(such as a possible file from the public files, or a file you uploaded that is infected) you could by executing the file locally get malware, however none of G.ho.st downloads contain malware and most likely your not going to upload a virus to your own account.
