Need Help with Trojans and malware

[TSRoger]

I did some of my own cleaning using otl.exe and then combofix, and I believe that helped alot.  I do have a few other minor infections, like with Firefox, for example.  I'd really appreciate it if someone could help me double check my work and eliminate the rest of the malware, making sure I did things correctly.  Thanks.

follow this guide and attach (not copy and paste) logs from Mawarebytes / OTL / aswMBR
http://forum.avast.com/index.php?topic=53253.0


if you have the combofix log....attach that also

[TSRoger]

See attached.  Thanks.

OK looks like your topic has flown under the radar and the malware removal specialists have missed it.

Even now there may be some delay due to differing time zones (2:35am in the UK) and availability of the volunteer malware removal specialists, work commitments, etc. Currently there are none of them on-line.

[TSRoger]

Okay, I guess I will wait patiently until someone can give me instructions on what to do next.  Thanks.

Hi sorry we missed you.. Could you attach the combofix log please

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

  [Reboot]
• Then click the Run Fix button at the top
  
• Let the program run unhindered, reboot the PC when it is done
• Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.

THEN

Download AdwCleaner from here to your desktop
Run AdwCleaner and select Delete



Once done it will ask to reboot, allow this
On reboot a log will be produced please attach that

[TSRoger]

I dont have the combofix log from last week's scan.  If you provide me proper instruction, I could create one again. (I dont have the combofix program installed anymore.)  Attached are the new logs, thank you!

[essexboy]

OK lets re-run Combofix as I feel it did not get it all first time round

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

[TSRoger]

No signs of trouble, everything seems to be running well so far.  Combofix log attached.  Thank you.  Do I need to delete combofix now?  If so, how?  Thx.

[essexboy]

Subject to no further problems   

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Run OTL

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

  :Commands
  [resethosts]
  [emptytemp]
  [Reboot]

• Then click the Run Fix button at the top
  
• Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

• Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
  
• In the Run box, type in ComboFix /Uninstall (Notice the space between the "x" and "/") then click OK
  
  
  
  
• Follow the prompts on the screen
• A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself. 

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

• Go to control panel
• Select folder options (Appearance > Folder options in category view)
• Select the View Tab.
• Under the Hidden files and folders heading select Do not show hidden files and folders.
  
• Click Yes to confirm.
• Click OK.

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

 Upgrading Java:

• Go to this site  and click Do I have Java
  
• It will check your current version and then offer to update to the latest version

SPRING CLEAN

To manually create a new Restore Point
 

• Go to Control Panel and select System
  
• Select System
  
• On the left select System Protection and accept the warning if you get one
  
• Select System Protection Tab
  
• Select Create at the bottom
  
• Type in a name i.e. Clean
• Select Create
  

Now we can purge the infected ones

• GoStart > All programs > Accessories > system tools
  
• Right click Disc cleanup and select run as administrator
  
• Select Your main drive and accept the warning if you get one
  
• For a few moments the system will make some calculations
• Select the More Options tab
  
• In the System Restore and Shadow Backups select Clean up
  
• Select Delete on the pop up
  
• Select OK
• Select Delete

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes.  Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

• Microsoft Windows Update

To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?

Keep safe  :wave:

[TSRoger]

Thanks a bunch.  However, I am still getting malware warnings, and my last avast scan picked up alot of potential threats.  I will say, though, that these don't look like any of the problems I had last time, so thats good.  Any instructions, please?  Or shall I do what you said in your last post regarding cleanup?  Thanks.

[Pondus]

and my last avast scan picked up alot of potential threats.  I will say, though, that these don't look like any of the problems I had last time, so thats good.

can we see what ?

[essexboy]

What is Avast detecting ?  Is it in the qoobox or OTL_Moved files folders

[TSRoger]

Here's what it's detecting.  Malware scan attached and a screenshot from an Avast scan (I dont know how to save an Avast scan log).

[essexboy]

OK it is detecting all the quarantined files .. So run the cleanup to remove those folders and then run Avast again
