@greyknight33 there's very few Linux viruses, they could easily be made but nobody does because they're targetting the biggest easy target. that said, just because windows doesn't know how to read your Linux partition and pretends it isn't there doesn't mean its safe from a virus targeting it. you could easily implement the filesystem in user space in the virus and write directly to the disk without windows filesystem support. lots of DBs work with raw disks like this and their own "filesystems"
