I was scanning my work machine today for viruses, and was a little disconcerted when it found one. I let the virus scanner continue to run. I checked it a little later, and noticed it had found over 300 viruses, I was really starting to worry now. The final count was over 6000.
The good news is the scanner was finding viruses I had in an archive file that was a test bed for an older version of one of our products. The bad news is the test bed is now worthless, because the scanner deleted all the bad files. Thankfully I have a backup of the data.
