Constant Web shield alerts
« on: October 17, 2013, 04:05:46 PM »
My sister asked me to look at her laptop. It was extremely slow. I suspected typical malware issues so I started by uninstalling several of the typical things installed by the unsuspecting users. The laptop was now fast enough to run a full virus scan, Mcafee. No threats were detected. Since I hate Mcafee I uninstalled it and installed Avast free edition. Immediately after connecting to the internet web shield alerts start (1-2 per second) and does not stop. They are all the same,
  • Object:2f4f4f.com/script.php?sid
  • Infection: URL:Mal
  • Process:C:\Windows\explorer.exe

This occurs without any applications open. It only occurs when an internet connection is made. A full boot scan by AVast only found two malwares [PUP] which were moved to the chest.

Searching for an answer here I saw this thread (http://forum.avast.com/index.php?topic=53253.0) explaining a process of saving log files for posting here. I followed all the suggestions and have attached the log files. The only problem was with Rouge killer. The application stops during the process of detecting high jacked policies. It apparently finds 4 of them but I am unable to clean them or obtain a log file.

Any advise would be appreciated. I have no idea what else can be done short of a full format reinstall. The internet speed remains about 10% of what it should be.

NOTE: I could only attach 4 logs per post. The OTL logs are in the next post.

My apologies. I thought this was the correct thread for Avast free edition. Apparentley, I should have read the WHOLE title. If this post can be moved there that would be great.

Thanks

: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
  • Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.
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.[/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

I followed your suggestions. The web shield issue has disappeared. The internet speed and overall performance seems quite good now. Attached are the log files from OTL scans (2) and Combofix.

I have know idea what any of those steps did but apparently your genius worked. I can't thank you enough! Maybe my sister will finally listen to me and purchase Avast rather than Mcafee lol.

Not at all! I'm quite impressed. Thanks again. BTW I told her the story. She said Mcafee was not able to walk her through this prior to giving it to me. She was so impressed she is ditching them for Avast.

Way to go sunshine :)

In that case methinks I will send you on your merry way :)

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:

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. 

Clear Restore Points

Right click Disc Cleanup and select run as administrator
When it pops up at the first prompt select OK after it has done some calculations the tabs will appear
Select More Options tab

: 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 and 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:

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 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:
