That's the last of it gone - just a little tidying up to do:

1) Run HijackThis as you did to generate a log, but this time click on 'Do a system scan only'.
Place a checkmark in the boxes to the left of the following entries, by clicking on them:

O2 - BHO: (no name) - {46A4E9D9-B30E-452A-8157-DBBEC8573B03} - C:\Program Files\VSAdd-in\VSAdd-in.dll (file missing)
O2 - BHO: (no name) - {75001ACD-EC81-4FBA-B871-5EC900E8EDC5} - C:\WINDOWS\system32\pmnnl.dll (file missing)
O2 - BHO: (no name) - {F18F04B0-9CF1-4b93-B004-77A288BEE28B} - C:\WINDOWS\system32\hockwdsb.dll (file missing)

O3 - Toolbar: &VSAdd-in - {74DD705D-6834-439C-A735-A6DBE2677452} - C:\Program Files\VSAdd-in\VSAdd-in.dll (file missing)


2) Delete the following folder if it exists:

C:\Program Files\VSAdd-in

As an example:
To delete C:\WINDOWS\system32\foldertogo
Double click the My Computer icon on your Desktop.
Double click on Local Disc (C:)
Double click on the Windows folder,
Double click on the System 32 folder,
Right click on foldertogo and from the menu that appears, click on 'Delete'


You are running an old version of Sun Java which needs updating:
  • Go here and click on the Download button to the right of Java Runtime Environment (JRE) 5.0 Update 9.
  • Accept the license agreement by clicking the radio button.
  • Under Windows Platform - J2SE™ Runtime Enviroment 5.0 Update 9, click the Windows Offline Installation, Multi-language link.
  • Go to Add/Remove Programs and remove any entries that refer to Java 2 Runtime Enviroment and then reboot your PC.
  • Navigate to and delete the following folder, if it exists: C:\Program Files\Java.
  • Finally double click the installation file that you downloaded earlier.

Your log doesn't appear to show a software firewall installed - if you have one, and i've missed it, please ignore this.
If you are relying the firewall that comes with Service Pack 2, then you need to install one. While the SP2 firewall is better than nothing, it doesn't monitor outgoing traffic, so anything malicious on your computer can 'phone home' at will.

There are a few free firewalls available.
Zone Alarm: Available here.
Kerio: Available here.
Outpost: Available here.

It is important to note that you should only have one firewall installed at a time, but you can download both to your Desktop and install each in turn to see which one you prefer.

I want you to run your PC as normal for a few days and when you are happy that everything is fine, do the following:

Update your anti-virus program,
Disable System Restore,
Boot into Safe Mode,
Scan your computer for viruses.
When you get the all clear, reboot into Normal Mode.
Re-enable System Restore,
Create a Restore Point.
This will give a clean Restore Point should you need it in the future.
A tutorial for System Restore is available here.

The reason for waiting is that if removing the malware has caused a problem, which it occasionally does, you can put your PC back to how it was before the fix. This will re-install the malware, but an infected PC is better than an expensive paperweight!

Some bedtime reading: This is a very good tutorial about keeping your computer safe and secure on the internet.
