The NTFS vaccine? I thought it has passed the beta stage long time ago? Anyway, thanks for the input. I did test BD's USB Immunizer and, while looked to be doing its job just fine I found that the ad popup is offensive and totally unnecessary. Also, I did some grave-digging and saw some discussions suggesting that BD's Immunizer is easily bypassable. Considering that I also had some successful experience in the past with Panda's USB Vaccine, I might just go with Panda again.
