Windows 7: Windows Security Center can't be started because of virus/malware

11 Feb 2013   #91

Windows 7 Ultimate, 32bit

It's a bit problematic to contact the school (as it is on another continent... ), but maybe they are willing to send me the password by mail. If not; are there any ways to change/remove this password? :)

Today I got a popup message saying that avast! had been deactivated I opened avast! manually, and it said that the real-time protection was running so I'm a bit confused. I am now running a full scan to check if the program can come up with some virus/malware. Any suggestions on what to do? I would be greatful :)

Are you also running SuperAntiSpyware, by any chance?

Try a repair of avast!:

Go to Control Panel > Programs & Features > uninstall a program, select: 'avast! Anti-Virus

Click the Uninstall/Change, and select: Repair

Reboot after the repair.

No, I'm not running SuperAntiSpyware.
The popup message said that both Windows Defender and avast! have been deactivated. Maybe the combination of these two programs caused this? I remember reading somewhere that you should only have one anti-virus program at a time, and I didn't know that I had the Windows Defender too.
The avast! full scan came up clean, and the program seems to be working. That's why I get confused when my computer tells me something else
The security center is still active though :)
The reparation of avast! was successful, but when I click the "Turn on now" next to the message in the Action Center that says avast! is deactivated a popup message appears asking "do you trust this program?". I then click yes, but the program doesn't start. I can start it manually though but the message "avast! has been deactivated" is still present in the Action Center even though avast! itself tells that all protection is turned on and everything is fine.

Will have to do some checking, and get back to you. I'm about ready to call it quits, gotta get some ZZzzsss.

Thought that Windows Defender was not an AntiVirus, but an AntiMalware program. There is a difference.

However, in Windows 8, WD evolves into an AntiVirus program.

Greetings Crumble,

Sorry that you are getting conflicting info from your computer. When you see popups like that or when you just want to show us stuff without having to type a lot to describe it - you can use the info in this tutorial to post a screenshot of what you want us to see: Screenshots and Files - Upload and Post in Seven Forums

Here is a description of Windows Defender as it applies to W7:
Windows Defender - Microsoft Windows

Microsoft (unwisely?) named another product Windows Defender Offline:
What is Windows Defender Offline?

Like cottonball mentioned, Windows Defender is a full blown antivirus tool in Windows 8. Some have speculated that this is for some EU legal reasons.

I updated (via Windows Update) the list of things that Windows Defender looks for and then I installed and updated Avast. The two of the seem to be getting along just fine (as they should). If Avast did not want Windows Defender to run, it could simply disable it. Other antivirus tools disable Windows Defender without any problems... so this tells me that Avast expects to get along with Windows Defender. Here is the version that I have:
Windows Security Center can't be started because of virus/malware-avast.png

I did a repair of Avast (even though it was working for me) and I did not see any issues. My Action Center has no messages - even when I disable the 8 parts of Avast - so I cannot test that.

avast! AntiVirus is insatlled, and so is Malwarebytes AntiMalware. So, you are good.

Thanks for the info, UsernamIssues.

Came up with the same...Windows Defender (WD) is an AntiSpyware program in Windows Seven.

Also, early on, from Post #4, FSS shows that WD has been disabled:
Windows Defender:
WinDefend Service is not running. Checking service configuration:
The start type of WinDefend service is set to Disabled. The default start type is Auto.
The ImagePath of WinDefend service is OK.
The ServiceDll of WinDefend service is OK.

Looks as if we all have the same version of avast!

On avast! deactivated in Action Center although avast! is running windows seven issue...

Please follow these instructions:
They deal with the issue of Action Center in Windows 7 reporting that antivirus program cannot be found on the computer although avast 7.x is completely installed and fully active.

Read them first, and, if you have any questions, let us know.

If, after you are done, the same problem appears, then, uninstall avast!
Use the following:
avast! Uninstall Utility | Download aswClear for avast! Removal

Once the program is uninstalled, an the computer is restarted, install avast! once again, and let us know how it is going.

Microsoft Windows 7 Ultimate 64-bit

I had Avast just literally chit the bed in her Win7 Home Premium computer one day, it just wouldn't run. Did a whole bunch of uninstalling reinstalling, googling, forum reading, cussing and couldn't figure out what happened nor could I get it to run again.
The avast in my Win7 Ultimate works just fine so I dunno.
Ended up installing MSE on her computer and just gave up on why Avast stopped working on her comp that day.
