Query: Warning: VIRAL software. Don't buy this device!

While this could have been a good product, from a company I once considered a top supplier of Flash memory, MP3 players, and other products, this device includes U3 VIRAL software that takes over the host PC and forces itself into the system. The maker, Sandisk, claims that it can be removed, but that is a blatant lie. The software resides on an apparently permanent partition of the device, making the device a 1.9GB storage rather than the advertised 2GB. The accompanying software that is supposed to remove the U3 virus from the device does not even recognize that the device is attached, then fails to remove the offending virus. There is NO WAY to use the device as a normal flash drive.Despite the previous dozens of Sandisk products I own and use, this is the LAST time I'll EVER buy a Sandisk product!
