For users who are concerning their removable drive like USB flash drive, external hard disk or memory cards. Get the free USB pen drive from Panda company. I think it’s very important nowadays to prevent those kind of virus spreading. Although it still a beta program, I recommended who used USB pen drive and external hard disk should install it, even business user should also install. This will improve your PC security more if you using freeware anti-virus.
