Help with possible virus
« on: July 05, 2011, 03:41:07 PM »
Hello community,

I am hoping that you will be able to provide me with a solution to a problem with friends family PC.  They are having the following problems:
the Desktop is a DELL running Windows Media Centre (fully updated):

- the PC is unable to connect to the internet despite the router working fine (their netbook connects wirelessly without any issues)
- no connections are showing when attempting to access them through control panel
- the PC is crashing to the attached screen when attempting to do a fresh install of Windows
[img]BlueScreen.JPG/img]

I have attempted the following to remedy their issues but to no avail:
- Full scan with Avast
- Spybot Search & Destroy
- Malwarebytes Anti-Malware
- Multiple attempted re-installs of Windows
 
Below is the Hijack This log I ran off the system.

Any help you could offer would be greatly appreciated.

Regards
Dale

hello dale we first need to see ots log so

Download OTS to your Desktop and double-click on it to run it
  • Make sure you close all other programs and don't use the PC while the scan runs.
  • Select All Users
  • Under additional scans select the following
Reg - Disabled MS Config Items
Reg - Drivers32
Reg - NetSvcs
Reg - SafeBoot Minimal
Reg - Shell Spawning
Evnt - EventViewer Logs (Last 10 Errors)
File - Lop Check

  • Under the Custom Scan box paste this in

%SYSTEMDRIVE%\*.exe
/md5start
volsnap.*
explorer.exe
winlogon.exe
Userinit.exe
svchost.exe
/md5stop
%systemroot%\*. /mp /s
hklm\software\clients\startmenuinternet|command /rs
hklm\software\clients\startmenuinternet|command /64 /rs
CREATERESTOREPOINT

  • Now click the Run Scan button on the toolbar. Make sure not to use the PC while the program is running or it will freeze.
  • When the scan is complete Notepad will open with the report file loaded in it.
  • Please attach the log in your next post.
Edited to add custom scans

Please ensure that all logs are saved in the ANSI format

Hi dp25,

Where hjt as a detection tool is now obsolete and left, I still tried to give you the analysis results I could find on your scan log:

You could fix the following entries as PUP or possibly unwanted riskware:

R3 - URLSearchHook: uTorrentBar Toolbar - {bf7380fa-e3b4-4db2-af3e-9d8783a45bfc} - C:\Program Files\uTorrentBar\tbuTor.dll

O2 - BHO: uTorrentBar Toolbar - {bf7380fa-e3b4-4db2-af3e-9d8783a45bfc} - C:\Program Files\uTorrentBar\tbuTor.dll

O3 - Toolbar: uTorrentBar Toolbar - {bf7380fa-e3b4-4db2-af3e-9d8783a45bfc} - C:\Program Files\uTorrentBar\tbuTor.dll

uTorrentBar Toolbar <--If you do have some malware on your system and this is most likely,
this is the way how you got infected.
I would further check on the following system tasks:
lxedcoms.exe and lxedmon.exe, they  probably valid printer device monitor files,
but just check at virustotal for their respectable MD5 hashes to be genuine (5 definitions)

Do a full scan with MBAM after updating the software: http://www.malwarebytes.org/mbam-download-exe.php  and give the log as an attached txt file.

Now also scan with this tool and attach the logfile:  http://www.resplendence.com/download/sanitySetup.exe

If anything else is found we should inform essexboy here for a more in-depth investigation through the latest appropriate tools, and he might perform a cleansing routine,

Hi Asyn,

that made me feel a tad foolish - thanks.

Com155 please find attached the OTS log.

Polonus I have also attached the MBAM and sanitycheck.

Thanks for the help.

Hi were you doing an unattended installation ?

Also was the problem apparent before or after you installed the comodo firewall ?

Are there any yellow markers within Device manager ?

Hi essexboy, the issue occurred well after the installation of Comodo.

I can check tomorrow if there are any yellow markers in device manager.

Apologies but I am unfamiliar with the term unattended install. I was attempting to boot from CD and was planning
to do a fresh install of Windows that way.

Thanks
Dale

The reason I asked about the unattended install as there are some windows migration folders on the root of your drive.  I could remove them and that should help with a re-install

The info about device manager would be very usefull

Please download SINO by Artellos.
  • Save SINO to a place you can remember and run SINO.exe. (If you downloaded the ZIP version you will need to extract it first)
  • Then please check the following checkboxes:
Quote
System Info
Services
Boot Check
Tasklist
Startup Items
Event Log
Ipconfig
Ping
Netstat
Hosts file
Shares
Routing Table

  • Once checked, hit the Run Scan! button and wait for the program to finish the scan.
  • A notepad window will pop up. Please copy all of the content into your next reply.
Note: If you try to interact with the program once it’s started scanning it might appear to hang. The scan however will continue.
