URL:Mal infection of svchost.exe

Viruses and worms
1

Hello, I am having a similar issue to a number of recent posts: upon opening chrome, I begin to receive fairly regular (every few minutes) Avast notices of blocked infections, even if Chrome is running in the background (meaning, I am not actively navigating to any pages).

AVAST notification:
Object: http://opticized.net/…
Infection: URL:Mal
Process: C:\Windows\System32\svchost.exe

At first the infected file was alternately coming from chrome.exe and svchost.exe. In effort to fix the issue, I downloaded and ran Malwarebytes and performed an Avast boot-time scan. I am now no longer notified of the chrome.exe infection, but the svchost.exe still persists. Can you please assist?

I have attached the standard log files:

  1. Malwarebytes_log.txt
  2. FRST.txt
  3. Addition.txt

I also attached an image of the popup notification. I attempted to run aswMBR.exe, but the program did not appear to do anything, so I am unable to attach it’s log file.

Thanks in advance–I really appreciate any help you can offer!

You will need to uninstall chrome as it has been converted to developer mode

CAUTION : This fix is only valid for this specific machine, using it on another may break your computer

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

GroupPolicy: Group Policy on Chrome detected <======= ATTENTION CHR HKLM\SOFTWARE\Policies\Google: Policy restriction <======= ATTENTION Toolbar: HKLM - No Name - {318A227B-5E9F-45bd-8999-7F8F10CA4CF5} - No File 2014-10-30 14:34 - 2014-10-30 14:34 - 00000000 ____D () C:\Users\Guest\AppData\Local\Google 2014-10-30 14:34 - 2014-10-30 14:34 - 00000000 ____D () C:\Users\Guest\AppData\Local\Comodo 2014-10-30 14:34 - 2014-10-30 14:34 - 00000000 ____D () C:\Users\Bran\AppData\Local\Comodo 2014-10-30 14:34 - 2014-10-30 14:34 - 00000000 ____D () C:\Users\Administrator\AppData\Local\Google 2014-10-30 14:34 - 2014-10-30 14:34 - 00000000 ____D () C:\Users\Administrator\AppData\Local\Comodo 2014-10-30 14:34 - 2014-10-30 14:34 - 00000000 ____D () C:\ProgramData\9910a24b9c7a10b8 AlternateDataStreams: C:\Users\Bran\Local Settings:ymubyscP1LnNwhKJqo2mSAKwGH AlternateDataStreams: C:\Users\Bran\AppData\Local:ymubyscP1LnNwhKJqo2mSAKwGH AlternateDataStreams: C:\Users\Bran\AppData\Local\Application Data:ymubyscP1LnNwhKJqo2mSAKwGH AlternateDataStreams: C:\Users\Bran\AppData\Local\Temporary Internet Files:4dChymb2B0ynp9Xf1qkmI AlternateDataStreams: C:\Users\Bran\AppData\Local\Temporary Internet Files:LAWKnl4x0MlNUp5wP9RhAoJoK7iV EmptyTemp: CMD: bitsadmin /reset /allusers

Save this as fixlist.txt, in the same location as FRST.exe
Run FRST and press Fix
On completion a log will be generated please post that

THEN

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.

Thanks so much for the quick response!

I uninstalled Chrome as requested, then ran FRST followed by AdwCleaner. I’ve attached the logs from both program runs.

You can now re-install chrome if you wish. Have the alerts ceased ?

5

Yes they have! Thank you very much.

If all is well tomorrow let me know and I will tidy up :slight_smile:

All is indeed well–thanks again! Very impressed with the speed of your replies and success of your fixes.

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:

Download and run Delfix

: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article

I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

CryptoPrevent install this programme to lock down and prevent crypto ransome ware

Malwarebytes.

Update and run weekly to keep your system clean

It is critical to have both a firewall and anti virus to protect your system and to keep them updated.
