Malicious URL Blocked

Viruses and worms
1

Hi,

My PC seems to be infected with something that causes the above message. On startup, Avast alerts and the process identified each time is svchost.exe. This before any application is launched. The PC then launches Google Chrome with urls pointing the the avast site but nothing appears as the urls seem to be wrong. I can launch windows file explorer after some time but can’t launch any other app and the computer locks up and can only be stopped by powering off. On start up, there is a blue screen which identifies a problem with kdcom.dll and the pc will start with last known settings only to go through the loop again.

Ideas to fix anyone?

Thanks and regards,

Stephen

I’ve tried 3 times to run OTL with the custom text and Run Fix and each time the PC locks up and has to be powered off. It gets to stopping processes and dies.

I’ve been running the machine is isolation disconnected from the network which keeps it going longer.

Any ideas?

cheers,

Stephen

8

Continue direct to the TDSSKiller section please

9

The TDSS Killer files is too big to post so I’ve attached it. Hope that’s OK?

cheers,

Stephen

Re-run TDSSKiller and when you see this item select delete :

\Device\Harddisk1\DR1 ( TDSS File System ) -

Then retry the OTL fix run please

11

Ran TDSS Killer as requested and selected delete file.

Ran OTL again but it gets to Killing Processes and hangs. I leave it for some time but there’s no activity at all and no response to input.

cheers,

Stephen

12

Ah OK a rush of blood to the head MBAM is installed

Re-run OTL with this script

O20 - HKLM Winlogon: UserInit - (C:\Documents and Settings\Stephen\Local Settings\Application Data\nnnhultc\vtctfods.exe) - File not found
[2012/02/22 18:22:07 | 000,000,000 | —D | C] – C:\Documents and Settings\Stephen\Local Settings\Application Data\nnnhultc

[Reboot][/b]

OK done the new OTL run. Do I continue with TDSS Killer?

cheers,

Stephen

14

No, no need now. How is the computer behaving ?

15

Seems to be going fine. Thanks so much for helping sort it.

cheers,

Stephen

16

If all is well tomorrow let me know and I will remove my tools and tidy up

17

Today there hasn’t been any problems. Thanks so much for all your help.

cheers,

Stephen

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL
[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands [CLEARALLRESTOREPOINTS] [Reboot]

[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that
[*]Click Start.
[*]Open My Computer.
[*]Select the Tools menu and click Folder Options.
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[]Click OK.

It was a variation on the sinowal/tdl4 mbr bootkit

They are coming in lots of different flavours at the moment, a sort of mix and match
