This has never shown up until today

do you have Mcafee installed also.?

I noticed the tray icon.

That attachement is not entirely correct.It shows and states clearly that you have 2 real time anti-spyware programs running.One of these needs either removing or disabling.

It shows windows defender as turned off.
MSE turned off.

She only has McAfee SiteAdvisor

Excuse my ignorance here please but does windows 8 come pre-installed with MSE.?
I was under the impression that windows 8 came with a re-branded MSE called windows defender.

Midnights screenshot clearly shows MSE and windows defender as being installed and turned off.

Like i said before i believe the remnants of an earlier MSE installation could be still lingering on the system.

The Windows 8 computer I’m getting will have McAfee pre-installed.

I’ve never had MSE installed on this Windows 7 computer.

This a link for the removal tool for Mcafee products.

I find it strange that the action center is reporting that MSE is installed but currently turned off.
Only thing i can think that has happened is that at some point you have maybe had no av protection on your computer and windows has issued a windows update with MSE and you may have inadvertently installed it at some point.

Thats just a wild guess though.

I bought this computer sometime in mid 2012 and I didn’t install MSE but I had my neighbor come here and transfer all of my files and programs from another Windows 7 computer to this one so maybe that’s why it’s showing MSE.

maybe that's why it's showing MSE.
If you want to find out, give Essexboy a OTL log to look at

If this is windows 8 then it automatically disables defender when it detects another AV. You cannot uninstall it

As far as MSE and WD goes all they need to do is disable them and they won’t interfere with avast.

But that is not the OP’s issue. It’s getting her the action center to show avast is running.
My suggestion is one or more reboots might be needed.

Why is Avast still showing this? I don’t have Grime Fighter, or whatever it’s called, installed on my computer.

How can it find evidence of Grime?

In all honesty, I and probably others can’t really answer this question as we don’t know where you are at regards avast version number you have and how you got there.

Updating from the avastUI may retain the information that you previously had GrimeFighter (in early avast 9.0 betas) or if you didn’t do a custom install and specifically unchecked the GrimeFighter option.

Go to Control Panel/Uninstall a program/Avast/Uninstall-Change.Choose Change and uncheck Grime Fighter.
I did this after updating Avast from GUI although I didn’t see that Grime Fighter was installed.

Avast updated itself to Version 9.2011 so I didn’t see anything to tick or untick. I’m using the free Version and I thought Grime Fighter came with a paid Version.

@abruptum,
I’ve already done this 3 times and I saw nothing about Grime Fighter.

@abruptum

I done exactly what you told me to do and it showed nothing about Grime Fighter. Did not show anything to tick or untick. Rebooted and nothing changed.

I'm using the free Version and I thought Grime Fighter came with a paid Version.
It will most likely be a separate paid product. :)

I don’t understand why it shows “We’ve found evidence of Grime on your PC”.

Grime Fighter is kind of greyed out but when I click on it the screenshot is what it shows. ???

Well honestly I just dropped Iolo’s System Mechanic because my subscription to it was about to expire, interestingly enough I found that my computer worked even better without it being installed.

So im honestly wondering how effective this is at improving performance when I noticed more improvement by uninstalling System Mechanic and using a 3rd party defragger and ccleaner to clean up junk.

That is weird.Did you see option to choose which components to install like Web Shield,Browser Protection etc. ?
One of the component is Grime Fighter.

No, I didn’t see any options to choose anything.

Maybe this will help you:
