Great thread. I had Norton 2003 thanks to my school, updated the dat files then scanned your virii.zip file: it only found 3. Tried several times, only found 3. Uninstalled that and downloaded full version of Symantec Corporate Edition 8.0 through my school and updated the dat files, then scanned a new download of the virii.zip file (note the previous one was the one with 7 virii in it). Symantec only found 5. Hmm. Not good.
So, I went checking out the other stuff out there. Did the whole process over agagin using PC CIllin 2002 which came with my motherboard, updated the dats, and it only found 5. Argh.
Installed NOD32 updated dat files, and it found: nothing. Eh???
Unistalled NOD32 (just as I did with the other antivirus proggies before installing a new test program).
Installed Panda Titanium shareware, downloaded my 1 free dat update: scanned a new copy of virii.zip. It found: all 7 virii and trojans. Nice. I like the interface and I'll be buying it shortly. Good bye buggy Norton!!
