I recently lost my windows machine to a set of nasty viruses (stupid drunk roommates) and have physically isolated the drives and installed Ubuntu 9.04 to try to clean them up. I've never really used linux before, with the exception of its partitioning tools, so I'm a little lost.
I am running without an internet connection (it doesn't like my wireles card) so I can't use automatic updates, but I have the current vspupd.exe on a thumbdrive. The trouble is, Ubuntu thinks it's a zip file, which it isn't. How do I go about updating my virus definitions?
