I think that what probably happened is that the first time that you ran
Interferon, it got infected (this happened to me once when I forgot -- God
what a mess!).  So, Disinfectant did its deed, and cleaned things up.  Then,
when you ran Interferon again, the System got infected again.

The reason that Disinfectant doesn't get infected is b/c each time it is
launched, it performs a check upon itself and disinfects if necessary.  Then
it goes on with its other business (disinfecting your disks).

Maybe you should try running Disinfectant on your copy of Interferon...
