A Kaspersky support representative told me that problems could arise due to conflicts between the two and he said I should uninstall MBAM. I have both MBAM Premium and Kaspersky Pure 3.0 installed and running on a Windows 8.1 64-bit machine. I've seen various discussions here and elsewhere that address situations similar to mine, but not exactly. I'm new to this forum, so please excuse my ignorance, at least for now.
