solution hxdefdrv.sys

By galehickey2 ·
Solution that worked for me-
delete hxdefdrv.sys from the windows folder and then from recycle bin-
go into command prompt and type in NET STOP HACKERDEFENDER100 and hit enter-
ABOUT 45 seconds will pass and you will get a message "The service is not responding to the control function."
Reboot and hxdefdrv.sys sis not come back.

Part(I)

I was hacked by this application when I opened a web page in Internet Explorer.
Here is some information on hxdefdrv.sys (HACKERDEFENDER) and the removal instructions.

After noticing that something was wrong, I disconnected my pc off the Internet.

I noticed these changes to my system:

-There was a new shortcut in my desktop, with the name Start and this target:
"C:\Program Files\Internet Explorer\IEXPLORE.EXE" http://www.casinopalazzo.com/index.php?sourceid=100455

-After searching for the files created today, I found these new files in C:\Winnt\
.23052004.exe <-- The name of this file is the date of tomorrow
.hxdefdrv.sys
.sezzbc.ig2
.vzcdaq.2nh

-The Internet Explorer Start Page was modified to
http://rjgzvd.outhost.info/

-When trying to execute RegEdit.exe, this application was closed almost immediately.

-I deleted the file hxdefdrv.sys. After restarting the PC, the file had been recreated.

-To avoid the creation of this file again, open a command prompt and execute NET STOP HACKERDEFENDER100
Notice that this is the name of the service in the winunins.ini file (See winunins.ini below)

If the service is in memory, about 45 seconds will pass and you will get a message "The service is not responding to the control function.
If the service is not in memory, you will be told so.

After removing the service from memory, the hxdefdrv.sys file does not appear again when restarting the PC. Nevertheless, the application is still in memory, so that doesn't solve the problem completely.

Please, note that this service is not listed in the Task Manager, because it hides itself, some other services and files.

-I restarted my PC in safe mode and found another file in C:\Winnt
.svhost.exe
.winunins.exe
.winunins.ini

-After opening RegEdit, I found svhost.exe in the path:
1)
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
"Network Service"="C:\\WINNT\\svhost.exe -sr -1"

2)
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Network Service"="C:\\WINNT\\svhost.exe -sr -1"

-I found on the Internet, the site of the developers of this application in the url:
http://www.megasecurity.org/trojans/h/hackerdefender/Hackerdefender1.00.html
There you can get a better idea of its functionality

When I opened the winunins.ini file, I found this information -among other- in the [Settings] section:
ServiceName=HackerDefender100
DriverFileName=hxdefdrv.sys


To remove this application:
-Restart the PC in safe mode

-Open RegEdit and delete the keys:
1)
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
"Network Service"="C:\\WINNT\\svhost.exe -sr -1"

2)
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Network Service"="C:\\WINNT\\svhost.exe -sr -1"

-Delete these files frm C:\Winnt\
.23052004.exe
.hxdefdrv.sys
.sezzbc.ig2
.vzcdaq.2nh

- In RegEdit, find and Edit every Key containing ".outhost.", leaving them blank. I.e. The key
Default_Page_URL reads "http://ykkgcg.outhost.info/". Right click on it, select modify, delete the text and select OK. Please, note that you should look for ".outhost." I have noticed that The first part ("ykkgcg") is variable.

-Edit the host file, deleting everything and leaving only this line:
127.0.0.1 localhost

-Restart Windows in normal mode. Everything should be ok now. :-)
