Manually Deleting Virus

My PC is being infected with kavo.exe (W32.Gammima.AG, etc). I tried deleting it from the registry and folders. I do my best to clean everything but everytime i do a restart this virus comes back. Sometimes with the same name and sometimes with different names.

how can i really get it off my pc?  I do not want to reinstall my OS again. Is there a way to clean my pc from that virus?

If you are maually deleting a virus and you are sure that you have deleted all of it, and it keeps comming back then try turning OFF system restore before you reboot your computer to purge anything that may be hiding there, waiting to re infect your computer.
This will result in all your restore points being lost.
On re boot remember to restart system restore and make a new restore point.

Please be aware that if your computer fails to restart you WILL NOT have any restore points saved to use to roll back your system to a time when it was working

I am not even able to see hidden files or folders, not even in the safe mode i could see hidden files or folder. I also tried cleaning it in safe mode and still comes back.
I guess there is none solution without a system restore?

I tried this http://www.precisesecurity.com/computer-virus/gammima-ag-aug0730.htm  and nothing.

There is a likely a rootkit here preventing standard removal, and there may be other malware present too.

t would help if we could see what was going on with your computer. I suggest that you download, run, and upload a HijackThis log from the link below.

http://www.trendsecure.com/portal/en-US/threat_analytics/hijackthis.php

Click on "Do a system scan and save a log file" button. Post the text from the log file. Do not have HJT fix anything at this point.

Please do not post the log into the comment window. Use "Attach File" under the comment window to post the log.

Here is what I would suggest...

Download and Run ComboFix (by sUBs) You must run it directly from your Desktop.

http://download.bleepingcomputer.com/sUBs/ComboFix.exe

Disable your Anti-virus and any real-time Anti-spyware monitors that are running.
Then double click Combofix.exe & follow the prompts.
When finished, it will produce a log for you. Upload that log in your next reply with a new HijackThis log.  

Please do not post the log into the comment window. Use "Attach File" under the comment window to post the log.

Note 1: Do not mouseclick combofix's window while it's running. That may cause it to stall.
Note 2: Remember to re-enable your Anti-virus and Anti-spyware.

NOTE: If you have issues connecting to your network or internet after running combofix you can either simply reboot, or do the following:
* Going to Control Panel > Network Connections.
* Right click on their Network icons & select "Repair"
or
Alternately, if the Network icon appears in the notification area in the lower right corner of Desktop, right-click it, and then click Repair from the shortcut menu.

PLEASE ALSO NOTE: Combofix will typically fix most and sometimes all Malware entries but many times a script is also needed to finish cleaning up. So please keep CF until advised whether you need the script or not.

Hi IndiGenus,
Here it is the two log files, one for combofix and the other one for hijackthis. Now I was able to see the USB memory stick and the hidden files and folders. I'll wait for your replay. Thank you!

Looks like combofix took care of the issue. I'm not seeing anything else in the log that needs to be dealt with either.

You should remove combofix and it's associated files/folders.

Click START then Run...
Now type Combofix /u in the runbox  and click OK.  Note the space between the X and the U, it needs to be there.

The above procedure will:

Delete the following:
ComboFix and its associated files and folders.
VundoFix backups, if present
The C:\Deckard folder, if present
The C:_OtMoveIt folder, if present

Reset the clock settings.
Hide file extensions, if required.
Hide System/Hidden files, if required.
Reset System Restore.


I would also advise a full system scan with your Antivirus. Make sure it is fully up to date and let it either fix or quarantine anything it finds.

Thank you, it worked out perfect. Just one last question...Would it work for any computer that has the same kind of virus?

There were not any files named like that at the end. I found C:\QooBox
which had files of combofix. I deleted that folder, plus logs and stuff.
Thank you, good job!

Probably in many cases it would. But every case is different. There may be other instances of malware that prevent the fix or need fixing also. Each case needs to be assessed on a PC by PC basis. But combofix will do wonders with many of the current malware out there that can't be fixed using anything else. Just use with care...
