For couple of years, I have faced up a same situation for many times: eliminate virus on USB for myself and friends. I have ever tried a handful of solutions, both freewares and sharewares and some of them are really reliable, USB Disk Security is one of them, for instance!
However, this is a shareware application and you have to pay a some bucks to get it. Recently, I have found some other replacements in which BitDefender USB Immunizer is a really trusted name. As far as I know, a range of users have given the tiny application their belief! And today I will share with you what I have experienced with it.
