If you don't want to deal with virus at all, Use LINUX. I have been using linux since I knew about linux more than 10 years already and never had to deal with any of that virus crap.
If you have a friend who uses linux, plug your flash drive and the files will be there, remove all the suspicious looking files then it will be back to normal. Warning though, that if you plug it back to windows, it will get the same virus again.
