The Flash disinfector doesn’t work on Windows Vista and 7 any more the person who created the software hasn’t plan or decided to continue to Vista and 7, I’ve been using Panda USB Vaccine 1.0.1.4 a friend of mind used it on Windows 7 he doesn’t have a problem with it.
I’ve tried all the different programs out there, and decided on Panda USB Vaccine on all my machines with different OS’s. It works great for me and no conflicts with Avast or any other software.
