On the tv show App Central they showed a usb stick that had a virus checker on it. I didn't catch the name of it but you put it into your usb port and turn on your computer and it does the scan and fixes the virus for you. I think it works on boot viruses as well.
I'm computer illiterate and also cynical about anything advertised on TV. Since there are countless hackers constantly trying new viruses is it realistic for a product, the USB cure-all, to be up to date considering development, marketing, production and shipping times?
