Apt-cache and apt-get have been acting really strange for me lately. First Terminator disappeared off the list, and now I can't find ClamAV either. I tend to use my Kali live CD for generally anything I can, and read that you can use ClamAV with pretty much any live-boot linux CD to help clean up a messy Windows install. I was going to look at a friend's laptop for them and see if I could clean it and/or back up files.

Anyone have any thoughts on why I can't find ClamAV? Do I need to add some apt-get repositories to the appropriate config file?
