What would you like me to enter as the registry search term?

Here's the latest wpad.dat threat.

Well, you asked me to do this just recently, and the results are the same. This time I closed Outlook when I ran it.

Aye I did but if you look back then the first time you ran it nothing showed, but there was a result on the second run

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1
Link 2
 
VERY IMPORTANT !!! Save ComboFix.exe to your Desktop
 
* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
  • Accept the disclaimer and allow to update if it asks




  • When finished, it shall produce a log for you.
  • Please include the C:\ComboFix.txt in your next reply.[/b]
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.

3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.


Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

Here (attached) is the log from ComboFix. A couple of caveats. When it was running before the restart, it threw up a series of error messages, such as the ones I'm attaching about various files, saying first that it couldn't back them up and then that it couldn't backup and then couldn't restore several files in the C:\Windows\System32 (or maybe they were all in C:\Windows\System32\config, I'm not sure.) There were a total of maybe 5 or 8 such files, with two error messages for each.

Also, when the system restarted and ComboFix came back up to finish its process, there was an instruction to not run any other programs while ComboFix was generating the log, but it was too late for that, as some program automatically come up on my system at startup, and I hadn't known to turn them off. One of the programs that started at that point was the Avast virus protection you had indicated I should disable. I did disable it (disabled  all shields) but only until the "next startup" so it came up automatically after the startup. Please, let me know if I need to rerun ComboFix because of this.

Here is the fixlog. Avast was still generating detected threat warnings as FRST was running, and as soon as the comp came back up after reboot it generated another one. They're not all the same. One of them had the application as FRST iteslf! A lot of them are either about Outlook or Winword. The one that came up first after system reboot is about svchost. I'm attaching it. But they're all wpad.dat.

OK you will need to upload the zip analysis to a file sharing site or dropbox for me to collect

Download AVZ tool from here to your desktop
Unzip all files to a folder on your desktop
Open the folder and double click the AVZ icon
When the tool opens select "File" > "Standards scripts"


Place a tick in :

 
5. Update signature database


Then press "Execute selected scripts"


Once that has execute then
select "File" > "Standards scripts"
Place a tick in :

3.   Advanced  System Analysis with malware removal mode enabled


When finished look in the folder AVZ4 on your desktop
Open the LOG folder
Upload virusinfo_syscure to to a site for me to collect

Let me know if this stops it


FIX

Open AVZ as before
Click "File" > "Custom scripts"


A dialogue will open
Copy and paste the following script into the marked space then press run


Script for insertion :

Code: [Select]
begin
SearchRootkit(true, true);
SetAVZGuardStatus(True);
 DelCLSID('{E6FB5E20-DE35-11CF-9C87-00AA005127ED}');
 DelBHO('{2670000A-7350-4f3c-8081-5663EE0C6C49}');

 RegKeyParamDel('HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Shared Tools\MSConfig\startupreg\mobilegeni daemon','command');
 DeleteFile('C:\Users\J\Downloads\tools v5.3.1.zip.exe','32');
