usb virus removal software

which free usb virus removal software is good?

USB Fix

I use MCShield: effective and works well with CIS.

thanks

but both usb fix and MC shield are confusing for me. is there any other usb software available?

Confusing? Install MCShield, leave all settings in control panel at default, reboot. MCShield will scan your system drives at every boot, and new drives as they are connected.
