Title: can't enable shields
Post by: Devox on July 05, 2012, 05:33:55 PM
Hi, i am using vista-32 and i used to use Avira free antivirus, but yesterday it stop working so i try fix it and update it but still the real time protection didn't work. so i uninstall it and re-install it again but its also didn't work. so then i tried to use another antivirus so i installed avast free. but also the shields don't work and this time i can't even make update.

I suppose this means that my computer is infected.

So now, what should i do?

attached is a HJT log file, i don't know what is HJT but i found a lot of ppl ask for it and use it to identify the problem so i used it may it help.

Thanks.

OK I am not sure if OTL is strong enough to kill this but lets give it a whirl

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

Run OTL
THEN

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1  (http://download.bleepingcomputer.com/sUBs/ComboFix.exe)
Link 2 (http://www.forospyware.com/sUBs/ComboFix.exe)
 
VERY IMPORTANT !!! Save ComboFix.exe to your Desktop
 
* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here  (http://forums.whatthetech.com/How_Disable_your_Security_Programs_t96260.html&pid=494216#entry494216)

(http://img.photobucket.com/albums/v706/ried7/NSIS_extraction.png)

Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.
3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.



Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

Aye OTL lacked the oomph to kill the main driver... 

So lets try a different tack.. Delete the current copy of Combofix from your desktop
Download a fresh copy but prior to saving rename as Gotcha and try again... Meanwhile I will look for a stronger tool.  I think maybe Avenger next 
Title: Re: can't enable shields
Post by: Devox on July 06, 2012, 09:24:02 PM
just to be clear you want me to download a fresh combofix but rename before save and call it "Gotcha"?

You should be able to run Dr Web from Linux as it is a Linux based programme

Post by: essexboy on July 10, 2012, 10:12:36 PM
Lets see if GMER can locate it

Scanning with GMER

Before scanning, make sure all other running programs are closed and no other actions like a scheduled antivirus scan will occur while the scan is being performed. Do not use your computer for anything else during the scan.

(http://img.photobucket.com/albums/v666/sUBs/gmer_zip.gif)
Download GMER Rootkit Scanner from here (http://www.gmer.net/gmer.zip) or here (http://www.majorgeeks.com/download.php?det=5198).

Notes:
**Caution**
Rootkit scans often produce false positives. Do NOT take any action on any "<--- ROOKIT" entries 

-- If you encounter any problems, try running GMER in safe mode (http://www.computerhope.com/issues/chsafe.htm).
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Post by: Devox on July 11, 2012, 12:20:45 PM

Title: Re: can't enable shields
Post by: essexboy on July 14, 2012, 01:15:06 PM
OK I have been doing further research after Avenger failed to kill it..  Avenger works at ring 0 i.e one of the very first elements to run after the post test but there is a proof of concept ring -1 which starts even earlier and is therefore protected before Avenger even loads.. I wil not post the link for this as I do not want it to become common knowledge.  But suffice it to say it appears that you may have this type

Use of a tool outside of windows may kill it, but it appears that the control of the system is enough to stop an ISO being burnt 

Therefore I am afraid the only way to kill this is to reformat the drive, an overinstall or re-install of windows will not work..  You need to wipe the drive and start afresh
