Ok guys no problem at all with any antiviruses (like norton, symantec, etc.) or any other conflicts. This is simple as that. 1.45 version requires (earlier versions didn't) if you use a proxy server to access internet to enter it's specifications in mbam specific tab (settings -> update settings). That' all. Earlier versions didn't require to enter any specifications. Just put in your proxy's address and port and everything works fine. That goes to any update problems related to mbam 1.45.
