Hello, I hope someone can help me with a virus infection.
I was surfing the web using Internet Explorer, I usually use Firefox. A fake anti virus started running.
Microsoft Security Essentials immediately detected a Trojan:JS/BlacoleRef.W, Exploit:Win32/Pdfjsc.RM and after a search (I think) I found Trojan:WinNT/Simda.gen!A, another Exploit:Win32/Pdfjsc.RM and much later it found Rogue:Win32/FakeVimes (this was after I had run Malwarebytes I think. I later noticed the browser's Bing search was changed to findgala.com.

Oops, sorry. I forgot to do this thing:
I also forgot to tell about some of the symptoms, the fake anti virus made shortcuts to itself on the desktop, start menu and more. It also changed my hosts file and removed my redirects from different pop up/ad servers to my own machine. Stramgly, I think Combofix deleted the hosts file, so I created a new one. I also manually removed the virus from the allowed list in the firewall and from the list of start up programs in msconfig. I don't remember if that was before or after which scan.

Hi there and sorry for the delay, could you update me on the current problems please

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.
• Select All Users
• Under the Custom Scan box paste this in
  netsvcs
  %SYSTEMDRIVE%\*.exe
  /md5start
  consrv.dll
  explorer.exe
  winlogon.exe
  Userinit.exe
  svchost.exe
  /md5stop
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\NetBT /s
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\NetBIOS /s
  C:\Windows\assembly\tmp\U\*.* /s
  %Temp%\smtmp\1\*.*
  %Temp%\smtmp\2\*.*
  %Temp%\smtmp\3\*.*
  %Temp%\smtmp\4\*.*
  CREATERESTOREPOINT
• 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.
• Post both logs

THEN

Download aswMBR.exe ( 1.8mb ) to your desktop.
Double click the aswMBR.exe to run it Click the "Scan" button to start scan



On completion of the scan click save log, save it to your desktop and post in your next reply

[Orehg]

Thanks for the answer, and sorry I could not answer you faster.
There's no symptoms now. I have run both Security Essentials and Malwarebytes after this and they have found nothing. I think the virus infected me through Adobe Reader, so I have disabled the Adobe Reader plugins, and instead I'll download PDF-files and scan them for viruses before I read them.

OTL only gave me 1 log, but here's Extras.Txt from the last scan:

Heres the new OTL.Txt

And here's aswMBR.txt

'Tis always better to be safe than sorry... Looks to be fairly clean just a few hangers on to remove

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

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

If you have Malwarebytes 1.6 or better installed please disable it for the duration of this run

Run OTL

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

  :OTL
  IE - HKU\S-1-5-21-261483860-755350895-2409874645-1000\Software\Microsoft\Windows\CurrentVersion\Internet Settings: "ProxyServer" = 133.11.240.56:3124
  FF - prefs.js..extensions.enabledItems: {CAFEEFAC-0016-0000-0021-ABCDEFFEDCBA}:6.0.21
  FF - prefs.js..extensions.enabledItems: {CAFEEFAC-0016-0000-0023-ABCDEFFEDCBA}:6.0.23
  
  :Files
  ipconfig /flushdns /c
  
  :Commands
  [purity]
  [resethosts]
  [emptyjava]
  [CREATERESTOREPOINT]
  [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.

[Orehg]

Was that fix supposed to take hours?

Well, here's the log I got from the scan. And the hosts file were supposed to have those addresses there. Can I move the hosts file in _OTL folder back, and then delete C:\_OTL?

Edited by Orehg, 03 February 2012 - 01:10 PM.

[Essexboy]

As you have Vista and IE9 there is no real need for Host files of that length any more as smart screen filter handles them. This actually reduces the amount of time for IE to get to the websites as it does not need to read the HOST file

Certainly you can copy it back to the location.. I will remove OTL cleanly once you are happy


Any problems outstanding ?

[Orehg]

No, there doesn't seem to be any virus symptoms. Do I need to uninstall OTL or aswMBR?

[Essexboy]

Delete aswMBR from the desktop

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

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 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

• Click Start.
• Open My Computer.
• Select the Tools menu and click Folder Options.
• 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.

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

[Orehg]

Ok, no more problems. Thank you for all your help. I'll delete my logs now, since the only thing I changed was my user name and computer name, someone might be able to identify me.
