Hi essexboy,

The same alert has started appearing again since the last 2 to 3 days. Should I start another topic or can I post all the logs in this one itself?

MALICIOUS URL BLOCKED

avast Network Shield has blocked a harmful site.

Object: http:/

Infection: URL:Mal

Process: C:\Windows\system32\svchost.exe

It does not specify the website (http:/)

Hi there ... OK lets see what you have

Download OTL  to your Desktop
  • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.

  • Select All Users
  • Under the Custom Scan box paste this in
netsvcs
%SYSTEMDRIVE%\*.exe
/md5start
services.*
WSHELPER.*
explorer.exe
winlogon.exe
Userinit.exe
svchost.exe
/md5stop
CREATERESTOREPOINT

  • Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
    • Post both logs

Did you set the proxy in Firefox ?

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.[/b]
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

    Seeing nothing so far .. Are the alerts still occuring ?

    Download the latest version of TDSSKiller from
here and save it to your Desktop.
 
 
  • Doubleclick on TDSSKiller.exe to run the application


  • Then click on Change parameters.
     

     
  • Check the boxes beside Verify Driver Digital Signature and Detect TDLFS file system, then click OK.
     
  • Click the Start Scan button.
     
     
  • If a suspicious object is detected, the default action will be Skip, click on Continue.
     

     
  • If malicious objects are found, they will show in the Scan results and offer three (3) options.
  • Ensure Cure is selected, then click Continue => Reboot now to finish the cleaning process.

  • Get the report by selecting Reports

 
  • Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.
Please copy and paste its contents on your next reply.

The alert has not appeared since I have posted for help here. The system does seem a bit slow.  TDSSKiller report attached as I was unable to copy and paste..

Subject to no further problems   :)

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
    Quote
    :Commands
    [resethosts]
    [emptytemp]
    [Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
Remove ComboFix

  • Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
  • In the Run box, type in ComboFix /Uninstall (Notice the space between the "x" and "/") then click OK



  • Follow the prompts on the screen
  • A message should appear confirming that ComboFix was uninstalled
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
  • Go to control panel
  • Select folder options (Appearance > Folder options in category view)
  • 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.
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:

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
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:

I hope it is ok to add to this topic since I am having the exact same symptoms.

So I ran OTL as instructed above as well as combofix ad am going to run TDSSFix right now. Lets see if the nasty avast popups warning about malicious URLs will stop.

Not sure how to attach files here but if I copz/paste all the logs I am told the post is too long for this forum
