I have been testing PrevX in my VMWare environment which emulates a 5 user network with Windows XP.. It seems to run very well alongside with NOD32 V4.0.437.0. What lead me to discover PrevX was submitting some files to virustotal and PrevX detected a BHO that nothing else did. I plan on testing it in our environment at work to test it out. I was curious if PrevX resells through Dell ASAP.
