Hi, I can't find out what the 'huntsman' virus is, inputted to google and the only references (on the ifrst 2 pages) are for blackspider anti-virus.
Ask your friend what av software he/she is using that told him/her of the infection.
I use avast, so went to their page and searched, came back with no results. Also, searched on secunia (click here), no results, if any secunia should have come up with something.
Hope this helps.
