Avast is blocked by group policy

system · 2013-12-13T17:21:58.000Z

Hello, so a little while ago my pc was infected by a trojan and it blocked avast and malwarebytes but I managed to delete it with avg.
After I had deleted it, I installed avast again but I still got the same error. I scanned my pc many times with AVG but it couldn’t find anything. I also tried to scan with Esset smart security 7 but it didn’t find anything either.
So now I installed avast again but I still get the same error and I can’t fix it.
Could somebody help me with this?
Thanks

start a New topic in viruses and Worms forum section…

follow instructions and attach (not copy and paste) Malwarebytes / OTL / aswMBR logs. http://forum.avast.com/index.php?topic=53253.0

Oke thanks

system · 2013-12-15T09:24:33.000Z

Here are the logs from FRST

Hmmm… strange…since i asked for Malwarebytes / OTL / aswMBR logs :

Anyway a log expert is notified and will take a look

Intriguing this has specifically targeted Avast using group policy settings

Lets see if we can change that

Download the attached fixlist.txt to the same location as FRST
Run FRST and press Fix
A log will be generated please post that

Then try Avast

I can’t use malwarebytes either because it gives the same error.
Here is the log by the way.

Oke thanks it seems like my problem is solved thanks but I got one more problem since that virus got into my system I couldn’t use windows media player any more. And I can’t use it now either. What should I do?
I get an error saying : “failed to load control windows media player from wmp.dll. Your version of wmp.dll may be outdated. Make sure you’re using the control that was provided with you application.”

essexboy · 2013-12-15T19:53:18.000Z

OK download and run the correct version of SURT from here http://support.microsoft.com/kb/947821 and let me know if that cures it … For Malwarebytes do a full uninstall and re-install

essexboy · 2013-12-15T20:54:58.000Z

Continue with Magna as it is pointless us working at cross purposes

system · 2013-12-17T13:30:19.000Z

Nope didn’t cure it, magna says I should work with you.

essexboy · 2013-12-17T14:13:01.000Z

OK what are the current problems ? What version of windows media player do you have

system · 2013-12-18T12:35:35.000Z

I’m using windows media player 12, I get an error saying : “failed to load control windows media player from wmp.dll. Your version of wmp.dll may be outdated. Make sure you’re using the control that was provided with you application.” I downloaded and ran the version you said I should download but nothing has changed.

essexboy · 2013-12-18T14:11:41.000Z

OK lets re-install it next

Go to Control Panel > Programs and Features
Go to “Turn Windows Features On or Off”
Turn Media Features:Windows Media Player off
Reboot
Turn Media Features:Windows Media Player on again

system · 2013-12-21T07:10:33.000Z

It didn’t work, I dont get an error message now. I click and nothing happens.

essexboy · 2013-12-21T11:23:09.000Z

Have you installed any third party codecs ?

Download a fresh copy of media player from here http://windows.microsoft.com/en-GB/windows/download-windows-media-player

system · 2013-12-21T15:55:58.000Z

No I haven’t maybe the virus infected the wmp.dll in windows media player maybe we could replace that dll.
On that site you gave me wasn’t any download link for windows 7 ultimate.

essexboy · 2013-12-21T16:46:14.000Z

The link is for all variants of windows 7

We can check but I believe it may be corrupted as opposed to infected
