Tracking down why Network Shield keeps blocking any site every 2-5 mins

Viruses and worms
1

This is the third attempt to send this (I can see no evidence that it has been sent)

I get ‘Malicious URL Blocked’ warnings every 2-5 mins when my browser is just ‘on’ (I am connected to the internet permanently) Very annoying >:(

I use Avast 5 free and Firefox 5 on a windows 7 machine.

Malicious URL Blocked
Avast! Network Shield has blocked a harmful site

Object: 64.11.211.170 or 150
Infection:URL:Mal
Process: C:\Windows\SysWOW64\rundll32.exe

or C:\Users\PP\Appdata\BthEventLite\IanAuthenticationhid.dll

I have tried:

  1. Avast full scan (No problem)
  2. Avast boot time scan (No problem)
  3. Malwarebytes (No problem)
  4. Super antispyware (no problem)
  5. ESET online scanner (6 Malware items)
  6. Sophos antirootkit (no problem)
  7. OTS (log file in ANSI form enclosed

This warning doesn’t occur when I disconnect the internet. It seems as though this repeated warning is being triggered from within the PC. Has anybody any ideas about this one. (I can’t even find any leads on the internet)

Thanks Paul

Once you have run this could you let me know if the alerts continue

Start OTS. Copy/Paste the information in the quotebox below into the panel where it says “Paste fix here” and then click the Run Fix button.

 
[Unregister Dlls]
[Registry - Safe List]
< Run [HKEY_USERS\S-1-5-21-2849503422-394843391-3115920349-1000\] > -> HKEY_USERS\S-1-5-21-2849503422-394843391-3115920349-1000\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

The fix should only take a very short time. When the fix is completed a message box will popup telling you that it is finished. Click the Ok button and Notepad will open with a log of actions taken during the fix. Post that information back here

I will review the information when it comes back in.

Depending on what the fix contains, this process may take some time and your desktop icons might disappear or other uncommon behavior may occur.

This is no sign of malfunction, do not panic!

Thank you for getting back so quickly. (A good reason to stay with Avast !! - I hope they are appreciating you)

Here is the results file (ps I didn’t select Reg - Disabled MS Config items etc)

Thank you
Paul

Are the alerts still present ?

5

Not at the moment but yesterday evening we watched Iplayer without any interruptions. Can you keep this open until tomorrow just in case.

Thank you

What has caused this and how did it slip through Avast?

6

Yep we never close ;D

If you do get the alerts let me know and I will dig deeper

Have you just updated some codecs ?

7

No Codec update that is recent (last month)

Any other ideas where it might have come from? What is it, what is it called?

8

No name as such - it is new ;D

But if you could upload to Avast as undetected malware, they will give it one

The miscreant will be located in C:_OTS\moved files\C:\Users\PP\AppData\Local\BthEventLite\lanAuthenticationhid.dll

Open Avast and select virus chest
Right click in the white space and select add
Browse to the above location and click the bad file
This will now appear in the chest
Right click the file in the chest and select send to virus labs
Fill in the form as potential malware
Then manually update Avast to send it

9

Done.

PS No alerts so far.

Thank you

Thanks - once you are happy let me know and I will remove my bits and bobs

11

Hi

Still no alarms - looks like it is sorted.

Thanks

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:

Start OTS. Copy/Paste the information in the quotebox below into the panel where it says “Paste fix here” and then click the Run Fix button.

 


[Custom Items]
:files
ipconfig /flushdns /c
:end

Run OTS 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.

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

Upgrading Java:

[] Go to this site and click Do I have Java
[] It will check your current version and then offer to update to the latest version

SPRING CLEAN

To manually create a new Restore Point

[*]Go to Control Panel and select System
[*]Select System
[*]On the left select System Protection and accept the warning if you get one
[*]Select System Protection Tab
[*]Select Create at the bottom
[*]Type in a name i.e. Clean
[*]Select Create

Now we can purge the infected ones

[*]GoStart > All programs > Accessories > system tools
[*]Right click Disc cleanup and select run as administrator
[*]Select Your main drive and accept the warning if you get one
[*]For a few moments the system will make some calculations
[*]Select the More Options tab
[*]In the System Restore and Shadow Backups select Clean up
[*]Select Delete on the pop up
[]Select OK
[]Select Delete

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

http://img233.imageshack.us/img233/7729/mbamicontw5.gif

Malwarebytes. Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

[*]Microsoft Windows Update

To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ?

Keep safe :wave:

Hey there! I’m pretty much the exact same problem as Tycho except I’m on XP and am not nearly as tech savvy as him apparently. I don’t know what this OTS is or where to get it, and if I did I’m not sure if it would work since he is on Windows 7.

Any possible help boss?

Instead of the DLL messages mine come from here, also a different IP looking thing.

C:\WINDOWS\System32\svchost.exe

Hello guys same problem as both problems above except i am running vista.
object is 66.230.138.163
