Recurring Windows Malicious Software Removal Tool installation problem

That looks good!


Let's flush the DNS cache:
Right click on Command Prompt and choose to run as Administrator.
Copy/paste ipconfig /flushdns in the command and press the 'enter' key. It should show Successful DNS Flush when done. Reboot


Tell me if you're being re-directed after doing the above.

Open Control Panel, then Programs and Features ... see if Microsoft Malicious Software Removal Tool (KB890830)is listed in 'Installed updates' (left hand side). Remove it if it says failed.

Remove it from Installed updates, there may be more than one instance. It can also be found in C:\Windows\System32 as MRT.exe, and can be deleted.

This is how to remove AdwCleaner.........


Double click on AdwCleaner.exe to run the tool again. Click on the Uninstall button.
Click Yes when asked are you sure you want to uninstall.
Both AdwCleaner.exe, its folder and all logs will be removed.

Should I do that anyway or only if the update failed? Also, do I still need AdwCleaner or is it okay to uninstall it?

It may let next month's MRT install OK.

From the OP:

I don't think to install the updates right away. Rather, I just keep using my PC as usual until the updates install themselves

The problem with that is a) updates should be installed as soon as they are become available, if not for security reasons at least to stop them accumulating and b) that method ignores all the dozens of optional updates that are no doubt numbering quite a lot by now. I assume you have, in settings, Windows Update set to install updates for more components using Microsoft Updates, if not you should. The only optional updates that I would avoid are unwanted language packs if offered in your version of 7 and maybe things you prefer to update yourself such as graphics drivers.
I'll leave the question of failed updates to others. Just wanted to add my thoughts on one aspect of your question.
