unzip/rar everything. they are definately virus free, they are on my pc...
will get you a .rar tool. works just like .zip
but, spoke to someone about the BSoDeath problem, he said he had the same problem with those drivers, they wanted to install on a printer port and not usb and that created havoc and pc messed up.
try extracting all those files into a folder on desktop, run Device Manager to update drivers for the unknown webcam and point it that desktop folder rather than letting it install automatically.
best of luck
