My OS is Windows XP Professional 32bit. I have recently installed Kaspersky and Malwarebytes on a freshly loaded PC. Once both installed the PC locks up. I've disabled Malwarebytes and all works well. I need to know what exceptions need to be added to Kaspersky to allow for Malwarebytes to run also. I've added just the .exe to the virus exception list but this doesn't help. Thanks in advance.
