I have Prevx and MBAM Pro running together on a couple computers. I've experienced slowdown issues on boot up with one of the computers. Disabling MBAM Pro's Protection Module from starting with Windows has fixed that slow boot issue. Whether or not that has anything to do with Prevx is something I have not investigated further. I simply start MBAM manually after that machine boots. If I ever did determine that the conflict was between Prevx and MBAM, Prevx would be the program that I would keep. HTH
