I too once though that Microsoft should be able to provide good malware protection,so I tried Windows Defender for a year or so,it was almost usless,it would "popup" and detect changes in the system(Like Threatfire),but was totally usless at finding any malware,it never did.
It is not a malware scanner. It is a spyware scanner only. You are expecting it to do things it cannot do.
I'm also skeptical of Microsoft's new Security Essentials,as it requires you to remove all your present anti-malware,and rely solely on it.
No, it runs fine with MBAM. You shouldn't run two AV programs at the same time though. That goes for ANY anti-virus/malware program and not just MSE.
Also,has ANYONE ever ran Microsoft Malicious Software Removal Tool and had it actually find anything? Another useless MS tool...
I have never ran it myself but according to reports it is quite effective: http://en.wikipedia.org/wiki/Windows_Malic...re_Removal_Tool
In a June 2006 Microsoft report, the company claimed that the tool had removed 16 million instances of malicious software from 5.7 million of 270 million total unique Windows computers since its release in January 2005. The report also stated that, on average, the tool removes malicious software from 1 in every 311 computers on which it runs. As of 19 May 2009 Microsoft claims that the software has cleaned 859,842 machines from password stealer threats.
