If your MSRT scan log at C:\Windows\Debug\mrt.log shows that the scan is successfully running once a month I don't think there's any reason to be overly concerned, but what you're experiencing would certainly be annoying. It said it installed successfully, however when I check mrt.log it doesn't say anything about the new malicious removal tool. I wanted to give an update - later today I received 2 updates from Microsoft, one of the them being this month's removal tool. It has two reports for the August version: one on August 14 and the other September 10. Microsoft Windows Malicious Software Removal Tool Finished On Wed Sep 14 11:57:40 2016ģ2-bit Vista Home Premium SP2 * Firefox v48.0.2 * NIS v22.7.1.32 * MBAM Premium v2.2.1 Microsoft Windows Malicious Software Removal Tool v5.40, September 2016 ( build 0.0) Here's what my log looks like for this month's scan: If so, are there any error codes for the scan? A return code of "0 (0x0)" is normal and means "no infection found". Open the scan log for the Malicious Software Removal Tool (C:\Windows\Debug\mrt.log) in with Notepad or any other text editor and see if you can find entry for the September 2016 v5.40 of the tool.

I ran it, but it seems like it didn't do anything. I went to Microsoft's website and downloaded it to the computer.

I tried to install this month's updates today and all except one was successful - the malicious removal tool (KB890830).
