Malware preventing MBAM database update?


Recommended Posts

Following last Firefox update, Firefox was terribly sluggish. As time went on I could no longer even load web sites in any browser including IE. So, I turned to my trusty tool, MBAM. Problem is, it no longer works. Here is what I tried:

 

Logged in as admin under Win 8.1, I've done the following on my desktop:

 

-run mbam-clean-2.1.1.1001

-turned off Windows firewall and Avast

-installed mban-setup-2.1.9.1057

 

When the program tries to update, I'm given the message "unable to access update server" and the Database Version remains at v2015.06.03.03.

 

A scan will run and detect PUPs (I ran it in normal Windows mode--should I be in Safe mode?), but following the scan the Database Version remains the same.

 

Meanwhile, my Win 8.1 laptop, which is not running Avast, has no problem updating the database and running a scan.

 

So, I tried copying all the update files from my laptop to my infected desktop, but did not get any different behavior.

 

Please help!

 

I've attached log files.

I see a lot of errors, so Check Disk must be performed.

No change: still getting Database Version v2015.06.03.03 and then after clicking 'Update Now', MWB says 'Updating Database' but the progress bar stays empty for 30 s and then it looks like it's updating with a bit of progress color in it (like 5%), but then it switches to  'Unable to access update server'.

 

Do you think Check Disk and/or MWB is being canceled by malware?

 

Do I need to take the drives out of RAID for Check Disk to work correctly?

 

Thanks,

I don't think this is caused by malware.

  • Download the MBAM-Check tool from this page.
  • Run the MBAM-Check tool.
  • A black command prompt window will open briefly, then close. Afterwards a log file will open.
  • A new log file, CheckResults.txt, will be created on your desktop.
Once the CheckResults.txt file is created, please attach it here.

Before I submit the logs, here are more observations:

 

-all desktops connected to router via Ethernet are displaying the same behavior: I

       -can't load web pages such as gmail and youtube

       -updates for all applications (e.g. vpn client, malwarebytes, Windows) fail

 

-devices connected to router via Wifi don't have this problem

 

I phoned my ISP and they confirmed that there's no proxy set up and no static settings have been overridden in the Ethernet adapter.

They do suspect that a malware infection has spread to all machines through Ethernet. They actually pointed me back to using

the Malwarebytes tool . . .

 

These are work machines i.e. nobody is downloading anything that should cause this. . . I don't know what to do at this point.

All right, here are the logs for the two machines that use Ethernet.

 

M1 runs Windows 8.1 on ASUS/Intel with 2 drives in RAID. I did a cleanup on it about 6 months ago. But after updating Firefox in July, the browser got to the point where I couldn't even type into web forms without severe lags and loss of characters, let alone it not being able to handle heavy websites like gmail, youtube, bitbucket, etc. So, I uninstalled it this past weekend.

 

M2 runs Windows 7 Home on ASUS/Intel with a single drive. A cleanup hasn't been done on it in a while, but it's seldom used at all.

 

The network is just a home network with one router.

 

Thanks,

The symptoms this morning on the Win 8.1 PC are even worse. Very slow after startup and neither the start button nor the charms would come up at all, ever. I started the zoek program and once the console came up I closed it because I had forgotten to turn off Avast and firewall. Because I couldn't get to the firewall to turn it off, I decided to shut the machine down using WinKey-R. After selecting Shutdown, the system hung at a purple screen. After about 10 minutes I decided to hard shut down, so I held the on/off down for a couple of seconds. I heard the machine turn off. Then about a second later it rebooted itself, which has never, ever happened before. I shut it off hard again and the same thing happened. The only way to keep it off is to flip off the power supply. Help!
