SVCHOSt causes Mailicious URL popup

Viruses and worms
1

I recently reinstalled Avast after a failed experiment with McAfee. Now Avast has found a problem with SHCHost.exe that is causing the Malicious URL popup to come up constantly. I have attached the rquired files. I apologize ahead of time for doing attachemtns, but my files went over the 10000 character limit, even if I try to break it down in to seperate posts.

Ok here is the most recent scan, with the most recent updates, from Malwarebytes. Thank you

essexboy,

I did everything you suggested, and I am attaching the newest otl scan. However, Combofix needed to download Recovery, and it is stuck at 22.7% download. You said not to rerun it without reposting, so I am doing so. Thanks

8

OK lets try the manual installation, if this should fail then run combofix without the recovery console

Go to Microsoft’s website => http://support.microsoft.com/kb/310994

Scroll down to Step 1, and select the download that’s appropriate for your Operating System. Download the file & save it as it’s originally named.

Note: If you have SP3, use the SP2 package.

Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools

[*]Drag the setup package onto ComboFix.exe and drop it.

[*]Follow the prompts to start ComboFix and when prompted, agree to the End-User License Agreement to install the Microsoft Recovery Console.

http://img.photobucket.com/albums/v706/ried7/whatnext.png

[*]At the next prompt, click ‘Yes’ to run the full ComboFix scan.

[*]When the tool is finished, it will produce a report for you.

Please post the C:\ComboFix.txt in your next reply.

Ok got it to work. Here is the combofix.txt file.

10

That killed it ;D

How is the computer behaving now ?

11

Still getting the pop up I’m afraid, although about half as frequently. And my web browser is not 100% right. I seem to be missing a lot of icons and tabs on my web pages, especially games on Facebook. One game I can not even play.

12

Could you delete your current copy of OTL please and download a fresh copy

Also could you post a screenshot of the popup

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.exe
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 one notepad window.
[]Attach that log

13

Ok. I downloaded OTL again and here is the new log.

14

Here are the two screen shots. One is the pop up, the other is the TDSS report. The pop up seems to have gone away since running TDSS, but I still have red X’s and can’t play games. I have updated both Shockwave and Flash player but they did not help.
