Sony have still not found out that it is not a good idea filling up users pc's with hidden stuff :twak:. F-Secure warns about the Sony product Sony MicroVault USM-F fingerprint reader software that comes with the USB stick.
QuoteThis USB stick installs a hidden driver under c:\windows\ .The directory and files inside it are not visible through Windows API. If you know the name of the directory, it is e.g. possible to enter the hidden directory using Command Prompt and it is possible to create new hidden files
