Hi, could someone please help me with this problem?
Every few minutes or so a "malicious URL blocked" warning message pops up. They pop up regardless of which web browser I use (Chrome, Mozilla, Explorer). They also show different object names but a few that consistently pop up are (hxxp://yawszaw89.com/z/ or hxxp://oleolex98.com/z/)
I followed the instructions in "Logs to assist in cleaning malware" and have attached the logs to this post (adwcleaner, MBAM, OTL, aswMBR).
Any help would be greatly appreciated. Thanks in advance!

The google chrome uninstaller wasn't working so I manually deleted the files and reinstalled it. I hope that achieves the same effect. Unfortunately that didn't fix my problem.
Just fyi, I predominantly use IE as my web browser. I don't know if that makes a difference or not.
New OTL log attached.

Intriguing so I will need to look deeper
Download and Install Combofix
Download ComboFix from one of the following locations:
Link 1 (http://download.bleepingcomputer.com/sUBs/ComboFix.exe)
Link 2 (http://www.forospyware.com/sUBs/ComboFix.exe)
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 (http://forums.whatthetech.com/How_Disable_your_Security_Programs_t96260.html&pid=494216#entry494216)

- 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

How long does this program take? Its running right now but my computer almost appears frozen. No status windows are open, and I can't open any new programs (I tried to open task manager to see if the program was still running).
-
Has it started going through the stages 1 to 50 ?
If not then reboot the computer to safe mode and try again please
-
Finished Combofix but now Avast won't restart so i dont know if the problem is fixed?
Any suggestions?
Combofix log attached.

Just wanted to leave you an update. After many failed attempts at rebooting my computer in various settings (normal, safeboot, safeboot w/network), I did a clean reinstall of Avast which seems to have solved the problem of it not working. However, the annoying warning messages still pop up. (T_T)
Thanks again for you help on this matter.

Do you have other computers using your router ? If so are they recieving the alerts ?
I would like to take a different look at the MBR

I have tried to run RogueKiller three times now, however each time after I hit "scan" my computer goes to a blue screen with the message that "a problem has been detected and windows has been shut down to prevent damage to your computer". It goes on to say "Plug and Play detected and error most likely caused by a faulty driver." There is also technical notes at the bottom that say "***STOP: 0x000000CA (0x00000005, 0x8A576030, 0x00000000, 0x00000000)"

I think this may have fixed the problem! (^_^)
Mozilla browser has been open for 2 minutes and no annoying warning message! So far, so good.
Is there anything else I need to do?
TDSSKiller and OTL log attached.
-
Could you attach the TDSSKiller log at C:\TDSSKiller date time please
-
Sorry about that (I'm not very computer savvy). I think these were what you were looking for. I saw two files that had that file name so I've attached them both.
-
Re-run TDSSKiller with the same parameters
When you get to this element select delete :
\Device\Harddisk0\DR0 ( TDSS File System )
Avast will alert as it is being moved.
Once done let me know how the computer is behaving
-
Computer has been working perfectly for the last few days. No more warning messages YAYYY!!! . :) :) :)
Thank you so much for all your help!!! :D :D :D
-
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
: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
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
(http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg)
- 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- 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.
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 (http://www.malwarebytes.org/mbam-download.php).
Update and run weekly to keep your system clean
Download and install FileHippo update checker (http://www.filehippo.com/updatechecker/) 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 (http://windowsupdate.microsoft.com)
