Hi. Let's see if there are any remains...

Download DDS and save it to your Desktop from here:
http://download.bleepingcomputer.com/sUBs/dds.scr

Double click dds.scr to run the tool.

    * When done, DDS will open two (2) logs:
         1. DDS.txt
         2. Attach.txt

Save both reports to your desktop. Attach DDS.txt back to topic.

Ok. Except a couple of adware you have not active malware on your system.

 
--> The first thing you need to do is to install the latest version of avast antivirus.
The current version that you may download for free is avast 6.0.1091.


--> Next ...
Start >> Control Panel >> Add or Remove Programs

Uninstall:

Fast Browser Search Toolbar
Productivity 2.2 Toolbar:
Conduit Engine:
&Windows Live Toolbar:

--> Next...
Download CCleaner from here:
http://www.piriform.com/ccleaner

Run Registry & Cleaner tool. Also disable your unnecessary startup.
Tools >> Sturtup >> select unnecessery program >> disable

Do not disable these entries:
avast
ctfmon.exe

Disable all but left these if you have the habit to use them all.

I can't access add & remove program, though other items in control panel is still OK. Moreover, avast shows that it keep blocking redirect to two malicious sites. Plus, I can't use google chrome. Is my problem really solved?

It "seems" like my comp run normally again. A big hand to both magna 68 and Zyndstoff (aka Steven Gail). Please let me know if I have additional step to finish.

Well, as a matter of fact, "FixMBR" was the wrong button...

If this solved problem you're lucky. If the problem comes back, please come back here again.

It's always a good idea to wait for instructions when you are using an unknown tool...  ;D

Please rerun MBAM (update it via GUI update tab) and have it remove everything it finds.

Cheers

Hmm, strange that DDS did not show rootkit

TDL4 is rather tricky... (http://www.winboard.org/forum/images/smilies/smiley-301.gif)

You knew about this or... 'by heart  ;D

Obviously, it didn't...

Nope, but there have been more cases in the last days where some tools did not find anything, the symptoms were blocked URLs even without any browser running...

Besides that, I'm a wizard.  ;D

I believe it is new variant of TDLs rootkits...  :)
and it is therefore difficult to our diagnostic tools to identify presence of rootkit.

but again I am surprised that the mbr.exe in DDS did not listed info about TDL and it is in aswMBR.  :(
