Hello,

It's better to print out the next instructions or save them in notepad, because you also have to work in safe mode without networking support, so this page wouldn't be available then.
It is also important you don't miss a step and perform everything in the right order!!

°Please start with uninstalling Spyware & Adware Removal, because most probably this is another Rogue antispyware program with a bad reputation, giving false positives and charging money to clean it..
Reboot afterwards.

Download smitRem and save the file to your desktop.
Doubleclick it and choose install. This will create a new folder on your desktop with the name smitrem.

Please download the trial version of Ewido Security Suite here:
http://www.ewido.net/en/download/

Please read Ewido Setup Instructions
Install it, and update the definitions to the newest files. Do NOT run a scan yet.

* Reboot into Safe Mode`: ( without networking support !)
°To get into the Safe mode as the computer is booting press and hold your "F8 Key". Use your arrow keys to move to "Safe Mode" and press your Enter key.

* Start HijackThis, close all open windows leaving only HijackThis running. Place a check against each of the following if still present:

O2 - BHO: HomepageBHO - {e9ccf15d-4c68-4b5a-9e9a-8e12e4bd39bd} - C:\WINDOWS\system32\hp4778.tmp
O4 - HKCU\..\Run: [Spyware & Adware Removal] "C:\Program Files\Spyware & Adware Removal\SAR.exe" NoHint
O4 - Global Startup: Microsoft Office.lnk = C:\Program Files\Microsoft Office\Office\OSA9.EXE


* Click on Fix Checked when finished and exit HijackThis.
Make sure your Internet Explorer is closed when you click Fix Checked!

* Open the smitRem folder, then double click the RunThis.bat file to start the tool. Follow the prompts on screen.
Wait for the tool to complete and disk cleanup to finish.

* Now open Ewido Security Suite
Click on scanner

* Click Complete System Scan and the scan will begin.
* During the scan it will prompt you to clean files, click OK
* When the scan is finished, look at the bottom of the screen and click the Save report button.
* Save the report to your desktop

* Close Ewido

* Go to start > control panel > Display properties > Desktop > Customize Desktop... > Web tab > uncheck and delete everything you find in there. (except for "My current home page")

* Reboot back into Windows.

* Perform an onlinescan with panda: (please use this scanner instead of any other scanner!)
Panda Online
- Once you are on the Panda site click the Scan your PC button
- A new window will open...click the Check Now button
- Enter your Country
- Enter your State/Province
- Enter your e-mail address and click send
- Select either Home User or Company
- Click the big Scan Now button
- If it wants to install an ActiveX component allow it
- It will start downloading the files it requires for the scan (Note: It may take a couple of minutes)
- When download is complete, click on Local Disks to start the scan
- When the scan completes, if anything malicious is detected, click the See Report button, then Save Report and save it to a convenient location.
Post the contents of the Panda scan report, along with a new HijackThis Log, the contents of smitfiles.txt which is present on your Homedrive (C:\ in most cases) and the Ewido Log by using Add Reply.

It could be possible, after reboot that your system is using the windows classic theme again.
To restore this and set it back to XP-theme, rightclick on your desktop > properties > tab Appearances and choose Windows XP style again under windows and buttons.
Click apply and OK.

Thank you for your reply

couple of quick questions

the Spyware & Adware removal tool that you are refering to is not the Adaware SE or Spybot software that is intentionally loaded on this PC correct? You are refering to another program that I am unsure how it got on this machine.

And your ok with AVAST as the antivirus software?

Again thanks for your help

Nope, that's not Adaware Se and Spybot. There must be a program in your softwarelist present called Spyware & Adware Removal, and because you can't remember you downloaded and installed it, it is certainly rogue then, because those ones get installed in most of the cases without user knowledge.

If you can't find it in that add/remove list, don't worry, just delete the next folder C:\Program Files\Spyware & Adware Removal manually while in safe mode then.

And yes, Avast is OK :thumbsup:

Hello,

First of all, delete this entry from your favorites:
Free XXX Sites List.url

Then check and fix next entry in hijackthis again:

O3 - Toolbar: Yahoo! Companion - {EF99BD32-C1FB-11D2-892F-0090271D4F88} - C:\Program Files\Yahoo!\Companion\Installs\cpn\ycomp5_5_7_0.dll (file missing)

Can you give a bit more explanation about not saving favorites? Do you get an error or anything?

Yes, after you removed those items, you're done. :thumbsup:

Read here how to fix your favorites:
http://support.microsoft.com/kb/q180306/

To keep this clean in the future, I would suggest the following things:

Install Spywareblaster
SpywareBlaster doesn`t scan and clean for so-called spyware, but prevents it from being installed in the first place. It blocks the popular spyware ActiveX controls, and also prevents the installation of any of them via a webpage.

Avoid illegal sites, because that's where most malware is present.

Let your antispywarescanner(s) scan frequently and don't forget to update before.

And I do suggest you perform an online virusscan once in a while. (Housecall and/or Bitdefender). Because what one virusscanner can't find another one maybe can.
Also make sure that your virusscanner, the one that is installed on your system is always up to date!

Make sure your windows has the latest updates: http://windowsupdate.microsoft.com/

If you are having XP SP2, read here how to configure Security Features for Internet Explorer:
http://www.microsoft.com/technet/security/...xp/iesecxp.mspx

Also visit this Free Online Scanner for PC Health and Safety

More info on how to prevent malware you can also find here (By Tony Klein)
