avast! Web Shield has blocked a harmful webpage or file.

Viruses and worms
1

Object: hXXp://rtortern3.biz/task/4002
Infection: URL:Mal
Process: C:\Windows\System32\svchost.exe

The object changes every time avast! blocks another harmful webpage, and it happens at an interval of ~1 minute. This happens as long as the computer is connected to the internet and is on. All scans come back clean. I’ve read through the forums and found people have the same issue but each fix is dependent on their specific computer. I’ve also read through which programs to run and which logs to obtain, so attached to this message are those logs. They are from the OTL, MalwareBytes, and aswMBR scans, ran just prior to this message.

Thank you for your assistance. This has been happening for the past week.

EDIT: fixed the link so it wouldn’t link to the webpage.

Hi there Could you save the OTL log as ASNI please. Details in the screenshot and attach that

I will need at least two runs to kill this

Then …

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

  • IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

[*]Double click on ComboFix.exe & follow the prompts.
[*]Accept the disclaimer and allow to update if it asks

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

Martin, you should highlight what they need to change or put it in boxes…

Attached is the OTL.Txt file saved with the ANSI encoding.

Thanks Michael. It was no trouble; I figured out what he was trying to have me do.

6

Attached is the COMBOFIX log.

Hmm still coming up as Unicode, we will use another programme to get the payload

  1. Close any open browsers.

  2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

  3. Open notepad and copy/paste the text in the quotebox below into it:

Fcopy:: c:\windows\winsxs\amd64_microsoft-windows-com-base-qfe-rpcss_31bf3856ad364e35_6.1.7601.17514_none_c7f0e16b547f887d\rpcss.dll|c:\windows\system32\rpcss.dll

Save this as CFScript.txt, in the same location as ComboFix.exe

http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif

Refering to the picture above, drag CFScript into ComboFix.exe

When finished, it will produce a log for you at C:\ComboFix.txt which I will require in your next reply.

THEN

Please download Farbar Recovery Scan Tool and save it to your Desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

[*]Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
[*]Select both shortcut and additions at the bottom
[*]Press Scan button.

https://dl.dropboxusercontent.com/u/73555776/frst.JPG

[*]It will produce a log called FRST.txt in the same directory the tool is run from.
[*]Please attach all 3 logs generated.

8

Attached are all files requested. I saved the FRST file as both UTF-8 and ANSI.

9

Here is FRSTansi.txt. I could not attach in the prior message.

10

Hmm this has changed no payload files … How is the computer behaving now, any alerts

11

Same issues.

12

So after the last fix I did there has been no change and you are still getting the alerts

Please download AdwCleaner by Xplode onto your desktop.

[*]Close all open programs and internet browsers.
[*]Double click on AdwCleaner.exe to run the tool.
[*]Click on Scan.
[*]After the scan is complete click on “Clean”
[*]Confirm each time with Ok.
[*]Your computer will be rebooted automatically. A text file will open after the restart.
[*]Please post the content of that logfile with your next answer.
[*]You can find the logfile at C:\AdwCleaner[S1].txt as well.

13

It actually saved as [S0]. Regardless, I have attached it as requested.

If this has successfully fixed the issue (as far as I can tell, it has so far), how can I prevent this from happening once I return this to the owner and they take it home?

14

New symptom: Chrome pulls up webpages fine. Before all of these scans and such, so was IE. However, now IE will not load up any webpage. Any ideas as to why?

15

Possibly there may be a proxy set on IE

Please download MiniToolBox, save it to your desktop and run it.

https://dl.dropbox.com/u/73555776/minitoolbox.JPG

Checkmark the following checkboxes:

[]Flush DNS
[]Report IE Proxy Settings
[]Reset IE Proxy Settings
[]Report FF Proxy Settings
[]Reset FF Proxy Settings
[]List content of Hosts
[]List IP configuration
[]List Winsock Entries
[]List last 10 Event Viewer log
[]List Installed Programs
[]List Devices
[]List Users, Partitions and Memory size.
[*]List Minidump Files

Click Go and attach the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.

Note: When using “Reset FF Proxy Settings” option Firefox should be closed.
