Hijacked homepage?

Hi,

it has all began with avast! antivirus alerts - it found a trojan - Win32: StartPage-006. It was not able to treat it.

After this I downloaded Ad-Aware, Spybot, CWShredder and let them run.

They found something, removed it. But now, even the homepage of EI is often changed to e.g. www.msn.com...

What more, when spybot starts, there is always a funny message poping-up: Fehler bei Einfugen von RichEdit-Zeile. ERROR.

So, I would like to ask you for a help. (I have also switched the system restore function off) Here is my logfile:

Hello mandarinkaxx,

The first thing I would like to point out is that your Windows XP and IE are not up-to-date. Please go to windows update and update all critical files.

Next, Run HJT again and check these items and then on Fix:

Reboot the computer and post a new log here.

 

Hi Taz71498,

It took a little while to download and install all the updates.

Hi madarinkaxx,

Your log looks good now, although SpyKiller does not come recommended.

Please read: Why did I get infected in the first place

Regards,

Pieter

 

Hi Pieter,

thank you for your advices. I do not know why the spykiller is still shown in the Hijack This. It should be uninstalled and I cannot find it.

I use Java 2 Runtime Environment, SE 1.4.2_04. Is it OK or should I switch to something else?

Although the log file looks good, the previous problems seem to come back and some of the still remain:

-already mentioned funny message when Spybot starts
-error message after installation of Spyware Blaster (and also Spyware Guard) saying something about bad sector or a virus...

It looks like the trojan startpage is hidden somewhere in the system, because it becomes a rule: when avast! shouts it has found a trojan I will find spyware in my comp and the most of it is from CWS... After removing all the crap it changes my home page...

I tried Trojan Remover but I received the same message as in the case of Spyware Blaster...

Then I tried Trojan Hunter but it found just Savno.100 (it removed it)

Finally, I follow the instruction by symantec: http://securityresponse.symantec.com/avcenter/venc/data/trojan.startpage.html (Removed all the infected filles in safe mode, but I did not found any of the key entries to delete as it was recommended).

But just few minutes ago, there was another avast! warning...

Can you, please, help me?

mandarinkaxx

P.S. I am going to install Kerio Firewall, but I think, since the trojan is (in my opinion) in the system, it won't help in this case, but may prevent another attacks

 

Let's find out. Download http://tools.zerosrealm.com/dllfix.exe

Doubleclick it and install in folder of choice on the root drive, in your case C:\

Run start.bat and press option 1. 'output.txt' will be created in the folder

Please post that report

Regards,

Pieter
