Hi, First off its a great forum, u do get answers here. Thanks to admins and forum members. My query is kind of related to the topic discussed here, I have a paid version of Malwarebytes 1.46 , a 90 days subscription of Norton Internet security 2010, and Ad-Aware free version running on my system(windows 7-32bit). I have no conflicts between any of these, i've excluded mbam files from scan list of NIS 2010. My subscription to NIS 2010 will be over soon and I plan to use Avast antivirus free edition 5.0 there after. Please let me know if there is anything specific i need to do with Malwarebytes 1.46 running on my system before installing Avast free 5.0
