My pc got a load of viruses recently.

I did a boot time scan with avast and it showed, among others, 3 viruses on kernel32.dll, winsock.dll and winsock.dll.

Avast could not repair them so i sent then to the virus chest. But as you know they are os files and i now get an message saying "i.explore has encountered a problem." (I'm sure that this is in direct relation to winsock.dll file going into quarantine.)

The full list of viruses Avast scanned and sent to the virus chest:
dmari.exe
huunklac.exe
kernel32.dll
pnqgj.exe
TMP98.tmp
uxsnish.exe
wmsock.dll
wnwsock.dll
yddb.exe


i also scanned my pc with Super AntiSpyware in safe mode. It found and quarantined:
rootkit.SENEKA trace.
Adware.tracking.Cookie
Trojan.Dropper-Cogad
Trojan.Fake-Alert/Trace.

How do i fix my OP system files now?

Thanks in Advance!
 
haf u tried using the 8 steps as suggested? follow them one by one~ it helps a lot. i use avast too~ so don't forget to disable it when u use combofix.. or was it sdfix :)
 
ive installed comodo firewall with defence plus. (sorry i know you said ask first) If need be i can do that over again on your instruction.

I haven't installed java, as the pc is not connected to the internet.

Id like to point out i don't have java installed on the pc anyway. i will install the latest version, which i have already downloaded ready to be installed, once my system is clean again.

The 3 log files are attached.
 
Good job!

Good idea on Java also.

Things should already be better but we aren't there yet!

Another run indicated!
OK there were found/removed items in MBAM so we need to run again as the first run likely exposed things that were not even seen the first time.

So another MBAM run Quick Scan will likely find more. So UPDATE run again.

Mike
 
Regarding UPDATE, i'm not connected to the internet on that pc, but the program was only installed today so im assuming it has the latest updates on it?

Also, seeing as the scans are coming up clean does that mean the registry files are ok?

attached log file for the quick scan:
 
Likely so! But do nothing yet just follow my instructions and get clean first!

Is the internet not plugged up, or broken, I read all the thread and saw no commentary on this!
If it is broken we are almost ready to fix it.

OK do the following

Download SDFix to Desktop.

http://downloads.andymanchesta.com/RemovalTools/SDFix.exe

On Desktop run SDdFix It will run (install) then close.

Then reboot into Safe Mode

As the computer starts up, tap the F8 key several times.

On the Boot menu Choose Safe Mode.

Click thu all the prompts to get to desktop.

At Desktop
My Computer C: drive. Double-click to open.

Look for a folder called SD Fix. Double-click to enter SD Fix.

Double-click to RunThis.bat. Type Y to begin.

SD Fix does its job.

When prompted hit the enter key to restart the computer

Your computer will reboot.

On normal restart the Fixtool will run again and complete the removal process then say Finished,
Hit the Enter key to end the script and load your desktop icons.

Once the desktop is up, the SDFix report will open on screen and also be saved to the SDFix folder as Report.txt.
Attach the Report.txt file to your next post.
=========================================
Download ComboFix

NOTE: If you have had ComboFix more than a few days old delete and re-download.

Get it here: https://www.techspot.com/downloads/5587-combofix.html
Or here: http://subs.geekstogo.com/ComboFix.exe

Double click combofix.exe follow the prompts.

Install Recovery Console if connected to the Internet!

When finished, it will open a log.
Attach the log in your next reply.

The internet is connected only for this pc.

When you read comobo.fix log it'll state that a 'Install Recovery Console has not been installed'. I know that this isn't a good thing, i just dont want that pc anywhere near my connection!.

How risky is it to not have it installed?
Can the recovery console be installed at a later date?


Attached log files:
 
OK Combofix found items run again to confirm clean!

Yes Recovery Console can be installed from the window cd.

Are you saying it will not install via ComboFix?

Mike
 
I chose not to install it the first time.

I took the plunge and temporarily installed my internet connection to that pc. So the recovery console has been installed this time.

log file for the second combofix scan:
 
Ok Looks clean!

Good job!

One last thing to do!

Open MBAM click More-Tools then Run tool.
Code:
c:\windows\system32\qmgbdomi.exe
Paste the name in the box above into File name:
Then click OK to detete.

Post one more Combofix and HJT log to let me confirm it is gone.

Mike
 
OK John great job!

I would not hesitate to connect up now.

Report back the status now how is it running any remaining issues?

The disk temp and registy cleanups below are important do them.

Thread closing-------------------------------------------------------------------

Some of these tools update so often they require downloading again later if needed. But keep and run MBAM and SAS to maintain.

Remove ComboFix
Start-Run
type
combofix /u
Hit enter or click OK.

Please download OTCleanIt http://download.bleepingcomputer.com/oldtimer/OTCleanIt.exe

Save to desktop.

This will remove all the tools we used to clean your computer.


Double-click OTCleanIt.exe. Click CleanUp. Yes to the "Begin cleanup Process?"

Approve all if prompted by Firewall. Approve Widows Defender or other guards or security programs while OTCleanIt attempting access to the Internet to allow all.

If prompted to Reboot click, Yes.
OTCleanit will delete itself when finished, If not delete it by yourself.

-------------------------------------------------------------------------------------
Run CCleaner http://www.ccleaner.com/download/builds (get SLIM at bottom no Yahoo toolbar)
Run twice or more on Cleanup temps, then on left click Registry then Scan for issues also repeat till clean.

Run ATF-Cleaner http://majorgeeks.com/ATF_Cleaner_d4949.html Temp and Registry, repeatedly until no more found.

KCleaner ftp://ftp2.kcsoftwares.com/kcsoftwa/files/kcleaner.exe
Fantastic cleaner.
-------------------------------------------------------------------------------------
The issues can and are likely found is in System Restore so do the below

Start-Programs-Accessories-System Tools-Disk- System Restore and create a new Restore point. Name it "After cleanup at TechSpot".

Then Start-Programs-Accessories-System Tools-Disk Cleanup
Click OK to accept C:
Select all Boxes
Then click More Options
Here click System Restore and OK to "Are you sure" and the OK to Run.

As this runs it clears all but the most recent Restore Point but it does one other thing that can contain infested files and a huge amount of disk space.

It clears what is known as Shadow copies which are used by specialized back up programs.

This is if you have the Volume Shadow Copy running which is the default.
-------------------------------------------------------------------------------------

Every two weeks or so, run MBAM and SAS until clean.

They take a while, so leave scanning while you are sleeping working or watching TV. If not done under the gun they can be scheduled not to interfere with computer time.

If they find something they can not clean, then get back to us.

Additionally run CCleaner. ATF-Cleaner and KCleaner.
----------------------------------------------------------------------------------------
I have been using ThreatFire for more than a year, it just went from ver 3 to ver 4.

It was designed to be used with and to co-exist with other Virus scanners.

Additionally it uses a totally different process to protect. While conventional Virus scanners work from definitions ThreatFire works on recognizing Virus/Malware activity.

It's like looking at it with 2 sets of eyes and from a different angle.

It works like some Firewalls do to learn what is good/bad.

After install it will ask you about everything that could be a security issue. For example the first time you run IE or FireFox it will prompt you. You would answer to approve and remember the setting. From then on no more prompts about IE or FireFox unless the exe changes like in an update.

As it queries you about the prompt to help you determine to approve or not you can google it with one click.

Look at http://www.javacoolsoftware.com/spywareblaster.html

Run SpyBot ocassionally and use the Immunize function.
http://www.safer-networking.org/en/download/

I highly reccomend Hostman: Hostman http://majorgeeks.com/HostsMan_d4592.html

Download install run and allow it to disable DNS Client and select all Host files and then Update and install all host files.

A Disk Scan (chkdsk) and Defrag are in order.

Mike
 
Ive run though all clean up steps.

The pc is working really well!. :grinthumb

Thank you so much!

I just have a few questions...

When doing a registry scan for issues in ccleaner it asks 'would you like to back up these changes'... should i back them? and if so where?

Also can i delete the Hijackthis program?

And just a last question can i run the spybot tea timer alongside avast's resident scanner?

TIA
 
Yes backup! CCleaner will give it a name based on the date.

Yes delete HJT!

OK on Teatimer if it works ok!

Good luck!
