Welcome aboard

Please download ComboFix from Here or Here to your Desktop.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**

1. Please, never rename Combofix unless instructed.
2. Close any open browsers.
3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
   • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
   • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
   NOTE1. If Combofix asks you to install Recovery Console, please allow it.
   NOTE 2. If Combofix asks you to update the program, always do so.
   • Close any open browsers.
   • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
   • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
   • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
4. Double click on combofix.exe & follow the prompts.
5. When finished, it will produce a report for you.
6. Please post the "C:\ComboFix.txt"

**Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

Make sure, you re-enable your security programs, when you're done with Combofix.

DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!

Hi Broni

sorry it's taken so long to get back to you, I downloaded & ran combofix early this morning but nothing had happened after 3 hours so I had to go to work, when I came back tonight still nothing had happened so I closed down pc & ran again.

Hope that was ok to do, please see attached combofix log.

Cheers

You did just fine

Is Norton still complaining?

I strongly recommend, you uninstall RegVac Registry Cleaner. Registry cleaners are not recommended and here is why: http://miekiemoes.blogspot.com/2008/02/registry-cleaners-and-system-tweaking_13.html

=======================================================================

1. Please open Notepad

• Click Start , then Run
• Type notepad .exe in the Run Box.

2. Now copy/paste the entire content of the codebox below into the Notepad window:

Folder::
c:\documents and settings\Chris Milbanke\Local Settings\Application Data\ugpuhjbuv

DDS::
uInternet Settings,ProxyOverride = <local>
uInternet Settings,ProxyServer = http=127.0.0.1:5643

Registry::
[HKEY_LOCAL_MACHINE\software\microsoft\security center\Monitoring]
"DisableMonitoring"=-
[HKEY_LOCAL_MACHINE\software\microsoft\security center\Monitoring\SymantecAntiVirus]
"DisableMonitoring"=-
[HKEY_LOCAL_MACHINE\software\microsoft\security center\Monitoring\SymantecFirewall]
"DisableMonitoring"=-

3. Save the above as CFScript.txt

4. Close/disable all anti virus and anti malware programs again, so they do not interfere with the running of ComboFix.

5. Then drag the CFScript.txt into ComboFix.exe as depicted in the animation below. This will start ComboFix again.

6. After reboot, (in case it asks to reboot), please post the following reports/logs into your next reply:

• Combofix.txt

 

[Milbanke]

Broni Nortons not complaining, but it's keep flagging up high cpu usage in system 32 - whatever that means I dunno.

I've ran combofix again like you asked, it asked me if I wanted to update to a newer version so I did. Hope that was ok and hasnt messed up the scan, attached is the log for you.

Cheers
Milbanke

 

[Broni]

it's keep flagging up high cpu usage in system 32

Can you give me more details?

Did you get rid of RegVac Registry Cleaner?

=======================================================================

Uninstall Combofix:
Go Start > Run [Vista users, go Start>"Start search"]
Type in:
Combofix /Uninstall
Note the space between the "Combofix" and the "/Uninstall"
Click OK (Vista users - press Enter).
Restart computer.

=====================================================================

Download OTL to your Desktop.

* Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
* Under the Custom Scan box paste this in:



netsvcs
drivers32 /all
%SYSTEMDRIVE%\*.*
%systemroot%\system32\Spool\prtprocs\w32x86\*.dll
%systemroot%\system32\*.wt
%systemroot%\system32\*.ruy

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install|LastSuccessTime /rs



* Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.

• When the scan completes, it will open two notepad windows: OTL.txt and Extras.txt. These are saved in the same location as OTL.
• Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post them back here.

 

[Milbanke]

Got rid of Regvac, cant give any more details of norton flaggin up PCU usage as hasnt occured again as yet, if it does I'll get details for you.

Please see OTL scan results below, I've had to attach as a log for each as the message board said there were to many characters & it would have to be shortened.

Cheers

Your computer would greatly benefit from adding another 512MB of RAM.

Update your Java version here: http://www.java.com/en/download/installed.jsp

Note 1: UNCHECK any pre-checked toolbar and/or software offered with the Java update. The pre-checked toolbars/software are not part of the Java update.

Note 2: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications. If you don't want to run another extra service, go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter. Click OK and restart your computer.

Now, we need to remove old Java version and its remnants...

Download JavaRa to your desktop and unzip it to its own folder

• Run JavaRa.exe (Vista users! Right click on JavaRa.exe, click Run As Administrator), pick the language of your choice and click Select. Then click Remove Older Versions.
• Accept any prompts.

=========================================================================

Run OTL

• Under the Custom Scans/Fixes box at the bottom, paste in the following

Update Adobe Reader

You can download it from https://www.techspot.com/downloads/2083-adobe-reader-dc.html
After installing the latest Adobe Reader, uninstall all previous versions.
Note. If you already have Adobe Photoshop® Album Starter Edition installed or do not wish to have it installed UNcheck the box which says Also Download Adobe Photoshop® Album Starter Edition.

Alternatively, you can uninstall Adobe Reader (33.5 MB), download and install Foxit PDF Reader(3.5MB) from HERE.
It's a much smaller file to download and uses a lot less resources than Adobe Reader.
Note: When installing FoxitReader, make sure to UN-check any pre-checked toolbar, or other garbage.

======================================================================
