I had several infected files and had a problem with getting a black screen after logging in to my computer.  The log-in page would load then it went to a black screen with only the mouse pointer.  I started in safe and loaded Malwarebytes then scanned.  I also loaded Avast.  After scanning I had like 50 files which were listed and several Trojans.  When I removed them and restarted the computer it now loads after signing on but stays black for a minute.  It also gives me a notification that the module C:\users\owner\Appdata\Local\...\xhdkasdxwyth.dll failed to load. 

 

Any help would be appreciated

 

The machine is a dell with a 2.8 gig Pentium 4

running windows 7 service pack 1

32 bit os

2 gigs of ram

Please read the following information first.

 

You're infected with Rootkit.ZeroAccess, a BackDoor Trojan.

BACKDOOR WARNING

------------------------------

One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would advice you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

http://www.dslreports.com/faq/10451

When Should I Format, How Should I Reinstall

http://www.dslreports.com/faq/10063

I will try my best to clean this machine but I can't guarantee that it will be 100% secure afterwards.

I would change all my passwords and keep a close eye on all your sensitive accounts.

Let me know what you decide to do. If you decide to go through with the cleanup, please proceed with the following steps.

-----------------------------------------

Run RogueKiller again and click Scan

When the scan completes > click on the Registry tab

Put a check next to all of these and uncheck the rest: (if found)

 

[RUN][sUSP PATH] HKCU\[...]\Run : YSPack (regsvr32.exe C:\Users\owner\AppData\Local\YSPack\xhdkasdxwyth.dll [7][x]) -> FOUND

[RUN][sUSP PATH] HKUS\S-1-5-21-1634147349-3898299598-1348007063-1000\[...]\Run : YSPack (regsvr32.exe C:\Users\owner\AppData\Local\YSPack\xhdkasdxwyth.dll [7][x]) -> FOUND

[HJ INPROC][ZeroAccess] HKCR\[...]\InprocServer32 : (C:\Users\owner\AppData\Local\{23e62f84-5237-92e8-0a28-a37f7f55ecb9}\n. [x]) -> FOUND

Now click Delete on the right hand column under Options

-------------

Next click on the Files tab and put a check next to these and uncheck the rest. (if found)

[ZeroAccess][Folder] Install : C:\Users\owner\AppData\Local\Google\Desktop\Install [-] --> FOUND

[ZeroAccess][Folder] Install : C:\Program Files\Google\Desktop\Install [-] --> FOUND

Now click Delete on the right hand column under Options

-------------------------------------

Next:

Download the attached fixlist.txt to the same folder as FRST.exe.

Run FRST.exe and click Fix only once and wait

The tool will create a log (Fixlog.txt) in the folder, please post it to your reply.

Mr. C,

I finally had a free moment and when I used my computer today, I noted that "Avast" had identified the Rootkit Zero Access and asked to remove it.  I clicked ok and had the computer re-start and do a boot scan.  This was accomplished and several files were identified and I believe removed.  I noted several if not all of the files listed in your list under files to be removed from Rouge killer. 

 

I then ran Rouge Killer and deleted 2 files from the list of three files on the registry tab.  The second file you listed said "not able to be found" when I clicked it to be deleted.

By the way I saw on task manager that my CPU kept running at 100% I could not see what was hogging the CPPU until I clicked on "show processes for all users"  this showed that taskhost.exe was  using 90% of my CPU.  I then went into scheduled tasks/ running tasks and after reading blogs I stopped the reliability analysis task and voila it slowed to a crawl.  The only thing is that I can't find it in scheduled tasks... I only saw it in running task...
