Useing virtualization to to get rid of all viruses

[Command Center]

Hi

I want to download a few things from piratebay but I keep getting viruses when I do. If I create a virtual windows 7 machine using virtual box and download all the torrents, for example a ISO file. If I download it onto a virtual machine then put the ISO image on a usb and copy it to my host OS will this prevent my host PC getting viruses. I might even delete the virtual machine when I am finished with it, if I do will it delete all the virus on the computer that were installed on the virtual
machine or will the viruses carry over to the host OS.

Thank you for your time!

If you transfer files to the USB key that are infected with viruses, and you move them to the host, then yes, you are risking for the host to get infected.

A VM is not a preventative against an infection.
Anything infected that is copied to the host...the host will then be infected.
Further, some viruses can escape a VM, and infect the host anyway. Without you even copying anything.

Best way to prevent stuff like this? Don't download sketchy software.
