I have used my vista computer since vista was released and I was recently diging through files and in C:\programData I found two pictures one was a bitmap and the other was jpeg or png that looked the same as the fbi ransomeware virus but it has never effected the computer I have never seen the error or virus in work on my computer how can I determine if it is just a picture or if it is real thanks.
If you didn't format your Vista PC before getting it (maybe secondhand) it's probably a leftover from the ransomware virus when it was removed in the past. Just delete the file and any instance of anything related to the virus in the registry and the user data/settings and program data folders.
