I am losing control of my system. My homepage keeps getting changed, and Spybot finds the problem, says it is fixing it, but it is still there.

Here is the Hijack this log:

Herman – Thanks for sending your HijackThis log.

You are running Ad-Watch, whcih is good. But, it will interfere with the registry changes we are asking HijackThis to make in the fix below. So, you will need to disable Ad-Watch from protecting the registry until this fix is completed. Otherwise, it will undo the changes we want to make.


Since you will not be able to access this page in safe mode during this fix, please print these instructions now, or save them to your desktop, to help keep track of the steps.


To start,, follow this link for instructions to enable 'show all files' for your system.


1 – Please follow the instructions in this link below to download and run Spybot & AdAware SE: Spybot & Adaware Tutorial


Please let me know if anything can not be cleaned by these utilities.



2 – Run HijackThis, and press Scan, and put a check against the following entries, if they still show up. Make sure all browsers and program windows are closed except for HijackThis.

R3 - Default URLSearchHook is missing

O2 - BHO: (no name) - {549B5CA7-4A86-11D7-A4DF-000874180BB3} - (no file)

O2 - BHO: (no name) - {FDD3B846-8D59-4ffb-8758-209B6AD74ACC} - (no file)

O3 - Toolbar: FWN Toolbar - {3D0BDAB3-12F4-471C-8966-E35A2C6C7DE7} - C:\WINDOWS\System32
\FWNToolbar.dll

O4 - HKLM\..\Run: [Ad-watch] "C:\Program Files\Lavasoft\Ad-aware 6\Ad-watch.exe"

O4 - HKLM\..\Run: [WebRebates0] "C:\Program Files\Web_Rebates\WebRebates0.exe"

O4 - HKLM\..\Run: [updater] C:\Program Files\Common files\updater\wupdater.exe

O8 - Extra context menu item: Web Rebates - file://C:\Program Files\Web_Rebates\Sy1150\Tp1150\scri1150a.htm


Once you have selected all the items for HJT to fix, and remember to make sure all browsers and program windows are closed except for HijackThis, then click fix checked.


3 – Next, use Control Panel > Add/Remove Programs to remove any of the following malware that you find:

FindWhateverNow
'KeenValue'
'PowerSearch toolbar for IE'



4 – Reboot into Safe Mode (How do I boot into "Safe" mode?), then use Windows Explorer to delete the following lists of program files and folders, if they still exist.

C:\WINDOWS\System32\FWNToolbar.dll <– this file (may already be gone)

C:\Program Files\Web_Rebates\ <– this folder

C:\Program Files\Common files\updater\wupdater.exe <– this file


Please let me know about any problems with the file/folder deletes.


5 – Next, use "Start > Run" and type in "%temp%" (without the quotes). Delete the entire contents of that "temp" folder (use "Edit > Select All", press "Delete", click "Yes").

Then, Empty your Temporary Internet Cache completely. Close all instances of Outlook and and Internet Explorer, then use "Control Panel > Internet Options > General tab" and click the "Delete File" button. When prompted place a check in: "Delete all offline content", then click OK.

Then, use Windows Explorer to clean out ALL the other temp folders on your system (navigate to the folder, use "Edit > Select All", press "Delete", click "Yes"):

* C:\Documents and Settings\\Local Settings\Temp\
* C:\Documents and Settings\\Local Settings\Temporary Internet Files\
* C:\Documents and Settings\\Local Settings\Temp\
* Empty your "Recycle Bin".

Please let me know about any problems with the temp file deletes.


6 – Now, reboot normally and run either of these two Online virus scans: Panda Active Scan or TrendMicro Housecall and put on Auto Clean.


Now, reboot once again, and run HijackThis to create a new logfile. Repost it here, and if you had any problems with the steps outlined above, please let us know what they were. Your response and the new logfile will determine the next steps for this fix.

Thanks

Thank you for your help with my problem. I followed the directions you gave and it looks like I'm good to go. I ran Ad Aware and Spybot, abd still get several DSO exploit messages in Spybot, but when I track them down to the registry, they are not there. Maybe a false positive with Spybot?

Here is my current HiJackThis log:

Thank you for your help.

Herman – Congratulations, based on your last HijackThis logfile, no spyware was found. Good job!

The 'DSO Exploit' message in Spybot is indeed a false positive, and this reporting bug will be fixed eventually.

In closing…

Please allow me to suggest some prevention steps to keep your computer clean and secure going forward. You may have already taken a few of the steps, but it never hurts to take a quick look :)

1 – Use an AntiVirus Software, and be sure you update it at least once a week. There are several very good free programs available. Grinler offers an outstanding overview at Virus, Spyware, and Malware Protection and Removal Resources

2 – To reduce re-infection potential for malware in the future, I strongly recommend installing three free programs: SpywareBlaster, SpywareGuard, and IE/Spyad.

3 – Use AdAware SE and Spybot S&D; to regularly to scan your system.

4 – It is very important to make sure that both Internet Explorer and XP are kept current with the latest critical security patches from Microsoft. To do this just start Internet Explorer and select Tools > Windows Update, and follow the online instructions from there.

5 – I strongly recommend that you consider using a Firewall. Just by using a Firewall in its default configuration can lower your risk greatly. Check out what Lawrence Abrams has to say at Understanding and Using Firewalls

An excellent overview is: So how did I get infected in the first place?. Be sure to visit the browser test link at the end of the article to really see how secure your system is!!

Thanks
