I just got virtually the same error trying to update MBAM, except that the number in parentheses is different from the person who started this thread: MBAM_ERROR_UPDATING (12007, 0, WinHttpendRequest) I was attacked by spyware a few days ago and ran a full system scan using the free MBAM version, which found over 1000 Trojan Agents that ultimately were removed successfully. I got this UPDATING error after the repairs were done, so I uninstalled and reinstalled the free MBAM thinking that might solve the problem. But I'm still getting the UPDATING error. Here is my info: Windows XP 2002 home edition with service pack 3 (don't know if it's 32 vs. 64 bit) MBAM free version 1.46 database version 4052 I use a NetGear wireless router to connect to the Internet 512mb of RAM is installed on my desktop PC
