Hello again Scott

Please note that you should have Administrator rights to perform the fixes. Also note that multiple identity PC’s (family PC’s) present a different problem; please tell me if your PC has more than one individual’s setting.

Before we get underway, you may wish to print these instructions for easy reference during the fix, although please be aware that many of the required URLs are hyperlinks in the red names shown on your screen. Part of the fix may require you to be in Safe Mode, which may not allow you to access the internet, or my instructions!

Very little appears to be wrong with this PC. There is really just one HJT entry to fix, however a website appears in your trusted zone which I feel should not be there (DSSfordummies). I’ll include it’s removal in the fix, but if you put it there and want it to remain, just don’t use the 015 Fix. It is also worth doing an Ewido scan to be doubly sure of the cleanliness of the PC.

I note that you are running HijackThis from Desktop; please create a new folder for it (for example C:\Program Files\Hijackthis\Hijackthis.exe) and move the programme into it. It is very important you do this before anything else since backup files can be deleted if they are not within their own folder!

Firstly could you please disable Giant Antispyware from running during the fix, it may just hinder our attempts to change anything. Right click on the icon (looks like an archery target) in the task bar and click on Security Agents Status (Enabled) then click on Disable Real-time Protection. To re enable it, you follow the same steps but click on Enable Real-time Protection.

To start please download the following programmes, we will run them later. Please save them to a place that you will remember, I suggest the Desktop:

Killbox by Option^Explicit
CCleaner
Ewido Security Suite

Right click on this link Del 015 Domains.inf and choose Save (link) As. Save it to your desktop. Right click on that file and choose Install. It will run immediately (you won't be able to see anything happen). You may delete it afterwards

Install Ewido Security Suite it is a free version of the programme.
  • Install Ewido security suite
  • When installing, under "Additional Options" uncheck..
    • Install background guard
    • Install scan via context menu
    • 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.
  • The update will start and a progress bar will show the updates being installed.
    (the status bar at the bottom will display "Update successful")
If you are having problems with the updater, you can use this link to manually update ewido.
ewido manual updates
Do NOT run a scan yet.

Next, please reboot your computer in Safe Mode by doing the following:
1) Restart your computer
2) After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
3) Instead of Windows loading as normal, a menu should appear
4) Select the first option, to run Windows in Safe Mode.

For additional help in booting into Safe Mode, see the following site:

Safe Mode

[*]Launch Ewido, there should be an icon on your desktop, double-click it.
[*]The program will now open to the main screen.
[*]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.

Now that the updates have been installed do the following:
  • 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.**
    • You will need to step through the process of cleaning files one-by-one.
    • If ewido detects a file you KNOW to be legitimate, select none as the action.
    • DO NOT select "Perform action on all infections"
    • If you are unsure of any entry found select none for now.
  • 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 and include it in your reply.
Now close Ewido security suite.

Please re-open HiJackThis and scan. Check the boxes next to all the entries listed below.

O2 - BHO: netMonior Class - {85810C93-C14C-11D5-BC4B-0050BA28E4FE} - C:\WINDOWXP\System32\popkill.dll
O15 - Trusted Zone: http://www.dssfordummies.com

Now close all windows other than HiJackThis, then click Fix Checked.

Please install Killbox by Option^Explicit.

*Extract the programme to your desktop and double-click on its folder, then double-click on Killbox.exe to start the programme.
*In the Killbox programme, select the Delete on Reboot option.
*Open the text file with these instructions in it, and copy the file names below to the clipboard by highlighting them and pressing Control-C:

C:\WINDOWXP\System32\popkill.dll

*Return to Killbox, go to the File menu, and choose "Paste from Clipboard".

*Click the red-and-white "Delete File" button. Click "Yes" at the Delete on Reboot prompt. Click "Yes" at the reboot now prompt..

If you receive a message such as: "Component 'MsComCtl.ocx' or one of its dependencies not correctly registered: a file is missing or invalid." when trying to run TheKillbox, click download and run missingfilesetup.exe. Then try TheKillbox again.

There is almost certainly bound to be some junk (leftover bits and pieces) on your system that is doing nothing but taking up space. I would recommend that you run CCleaner. Install it, update it, check the default setting in the left-hand pane, Analyze, Run Cleaner. You may be fairly surprised by how much it finds. Also click Issues then Scan for issues – fix selected issues

Post back a fresh HijackThis log and I will take another look.




"Edit,
As there has been no reply from the original poster this topic is now closed,
Should you have any further problems please create a new Topic,

Thanks "
