As for the MSE staying in the "orange", if you are using CCleaner or any other 3rd party disk cleaner, make sure the boxes for "MS AntiMalware" and "MS Security Client" or anything else that looks like it has something to do with the antivirus, are NOT checked, as this will erase logs every time you run the cleaner and tell Windows that a scan hasn't been run. As for ("an error about Animalware executable not being able to run or something like that") - check in "services" that it is set to run "automatic" - Right click "my computer" - "manage" - "services & applications" - "services" - scroll to"Microsoft Antimalware" - right click it - click "properties" - under "startup type" click the down arrow to drop the menu & click "automatic" if it is not already set as so - click "apply" & exit.
As for malware itself, here are links to 3 great tools. There are lots of others out there, but, in my case, these 3 are the only ones that find anything. The Comodo CE is especially good for rootkits because it prompts you to restart during the process so it can access & scan "locked" files that can't otherwise be accessed while Windows is running.But feel free to try others if you think there are still problems. A few more are:
IOBit Malware Fighter (free)
Adaware (free)
Spybot Search & Destroy
(without "teatimer" function")
Norman Malware Cleaner
These 4 are pretty good, but kinda large, don't let that discourage you, after all if you're infected, you have nothing but time anyway. They just don't seem to help me anymore because I'm clean & have been managing to stay that way. GoodLuck
