For years I was asking people if they knew anyone who bought antiviral software that reported an uninfected computer. I never got a "yes" response. After the birth of antiviral software companies, (but prior to the internet), the largest freeware/shareware distributor in the US offered a reward to anyone who would send them a virus on disk. They had no takers.

I met people who insisted that their computers had been infected because their antiviral software told them it was. Some of those people did not have a modem, and loaded only commercial applications; ergo there was no vector (route for infection).

Nowadays the internet provides a vector and there have been a few epidemics. So I was thinking about writing an antifungal program. Because if you've had a viral infection, surely your computer is less resistant to fungus. And of course my software will verify that data fungus was present and has been safely removed.

I wouldn't tell people that software was suspicious just because an antiviral told me so. We've seen too many false positives, leading me to ask for specifics. When it comes to open software, show me the code!
