Hello - first posting on the forum and I see good information here. I know I am rather late to this particular question, but the subject is pertinent currently to my own Win7 Pro 64-bit computer, running Norton Antivirus and Malwarebytes Antimalware Premiun 2.2.1.1043. I have both active at the same time. I too noticed all the orange dot responses in the Norton history panel and wonder how that affects Malwarebytes function. However, my question now is regarding the listing of exclusions above, I am confused. The titles indicate a listing for a 32-bit and a 64-bit version computer. However, in the list under the title for the 64-bit, the items include "(X86)" . I thought x86 refers to a 32-bit version computer and now I do not know which list to include. Thanks for your help on this.
