Websites Blocked - Presumably By Virus

Hello!

I’ve got this suspected virus problem with my friend’s PC (Windows XP SP2) and am wondering if anyone can help me out. Let me tell you what I have already done and what I assume to be the cause of the problem.

The symptoms are that I cannot access lots of important websites, such as windows update, anti-virus sites, opera homepage, but even apparently unrelated ones like the German news magazine Der Spiegel, etc. This website-blocking thing appears to be a frequent feature of more recent viruses.

A quick look at the virus vault of AVG Free Edition tells me that over the course of the last few months, a number of viruses have been found, deleted and a copy kept in the vault. These were the following:
Trojan horse: StartPage.16.BD (se.dll)
Trojan horse: Dropper.ExeBundle.AH (crack22.exe)
Trojan horse: Dropper.Small.22.AV (Ati2mdxx.exe)
Java/ByteVerify (opr001PD.class, opr001PF.class)

Currently, neither AVG nor Sysclean (by Trend Micro) can find any more viruses. Nor do Trojan Hunter, CWShredder, Ad-Aware SE or Spybot find anything.
I did find two suspicious entries with HijackThis. Please let me post the log file below:

It seems to me that two processes

should be terminated and I did just that. I also deleted all temporary internet files and the whole content of the TEMP folder. Moreover, I flushed the DNS cache.
But all that doesn’t seem to have helped and I have sort of run out of ideas, to be honest.

I read somewhere that such viruses often proceed by a procedure called DLL injection and store their firewall-like instructions somewhere in the Windows folder. The only hint I could see about this is that the AVG scan log gives me lots of entries that appear to have been changed. In detail, it reports the result ‘change’ and the status ‘changed’ for the following entries, while usually it just indicates with an ‘ok’ that a file is allright:
Boot sector of disk C:
C:\Windows\System32\kernel32.dll
C:\Windows\System32\wsock32.dll
C:\Windows\System32\user32.dll
C:\Windows\System32\shell32.dll
C:\Windows\System32\ntoskrnl.dll

Could it be that these files have been changed by the virus? Or maybe the problem lies in a completely different place…. In any case, I’m utterly clueless and would appreciate any suggestions from you guys.

Cheers,

Welcome to Lockergnome.

Please print out or copy this page to Notepad. Make sure to work through the fixes in the exact order it is mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. You should 'not' have any open browsers when you are following the procedures below.

Please download Ewido Security Suite at http://www.ewido.net/en/download/.

1. Install Ewido Security Suite.
2. When installing, under 'Additional Options' uncheck:
* Install background guard
* Install scan via context menu
3. Launch Ewido, there should be an icon on your desktop, double click it.
4. The program will now open to the main screen.
5. When you run Ewido for the first time, you will get a warning 'Database could not be found!'. Click OK. We will fix this in a moment.
6. You will need to update Ewido to the latest definition files.
* On the left hand side of the main screen click update.
* Then click on Start Update.
7. The update will start and a progress bar will show the updates being installed. The status bar at the bottom will display 'Update successful'.
8. Exit Ewido. DO NOT scan yet.

If you are having problems with the updater, you can go to http://www.ewido.net/en/download/updates/ to update manually.

Download CleanUp! http://cleanup.stevengould.org/ (Alternate Link if main link don't work - http://www.greyknight17.com/spy/CleanUp.exe ) and install it. Don't run it yet.

Download Hoster http://www.greyknight17.com/spy/Hoster.exe and run it. Choose the 'Restore Original Hosts' button and press OK.

Restart your computer and boot into Safe Mode by hitting the F8 key repeatedly until a menu shows up (and choose Safe Mode from the list). In some systems, this may be the F5 key, so try that if F8 doesn't work.

CleanUp! deletes EVERYTHING out of your temp/temporary folders, it does not make backups. If you have any documents or programs that are saved in any Temporary Folders, please make a backup of these before running CleanUp!. Run CleanUp! and click on the Options button. Uncheck 'Scan local drives for temporary files'. Also uncheck those two Newsgroup entries if you don't want to delete them. Click OK and then click on the CleanUp! button. Let it run. After it's done, choose Yes to logoff.

Now open Ewido and do a scan on your system.

* Click on scanner
* Click on Complete System Scan and the scan will begin.
* NOTE: During some scans with Ewido it is finding cases of false positives.
o You will need to step through the process of cleaning files one-by-one.
o If Ewido detects a file you KNOW to be legitimate, select none as the action.
o Do NOT select 'Perform action on all infections'
o If you are unsure of any entry found, select none for now as the action.
* Once the scan has completed, there will be a button located on the bottom of the screen named Save report
* Click Save report.
* Save the report .txt file to your desktop or a location where you can find it easily.

Restart your computer and post the Ewido log and a new HijackThis log.
