Annoying Popup every few seconds: MALICIOUS URL BLOCKED

Viruses and worms

Avast! is showing this popup:

MALICIOUS URL BLOCKED

avast! Network Shield has blocked a harmful site

Object: hxxp://xxxxxxxxx.com/x/
Infection: URL:Mal
Process: C:\WINDOWS\System32\svchost.exe

It seem to be adware trying to call home. It’s trying to connect with 5 or 6 different sites, e.g., credit, loans, merchant accounts, etc.

Neither avast! nor MBAM appear to be able to find it.

I’ve posted and attached the logs.

Help will be appreciated!

Could you attach the log located at C:|TDSSKiller date time please it will be bigger than the one you posted

6

Here is the correct TDSSKiller report attached.

7

Re-run TDSSKiller with the same parameters
When this element appears then select delete :

\Device\Harddisk0\DR0 ( TDSS File System )

Avast will alert

Once done could you let me know what problems remain

8

Hi,

Re-ran TDSSKiller with the same parameters
and the element did not appear:

\Device\Harddisk0\DR0 ( TDSS File System )

Avast did not alert.

9

OK how is the computer behaving now ?

10

Hi essexboy,

The Popups have stopped.

Thanks very much for your patience and help…

How can this problem be prevented, and will Avast attack it in the future?

11

The malware changes on an almost hourly basis, but if it does get in then Avast will block it from accessing then net

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 [resethosts] [emptytemp] [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.

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

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

If you use on-line banking then as an added layer of protection install Trusteer Rapport

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:
