Hello everyone, I am currently running Windows Vista Ultimate on an ASUS laptop. The current antivirus program I have include McAfee antispyware and antivirus 8.5i, windows defender and Malwarebytes' anti-malware. I currently have detected three infections so far from these programs. Malware found a rookit called mrxdavv.sys and a Trojan called kwave.sys, although i tried to remove them though anti-malware, they are still detected after reboot, so i guess there is another infection that is re-creating them, this is when I found another rookit through McAfee called NTOSKRNL-HOOK, and same thing happens with this, it always comes back after reboot, I have been looking for solutions for two days and it looks like all three infections are serious. I caught them from my cousin's laptop because hers was infected too and now it spread to mine through my flash drive. I have tried formatting and rebuild her system but it did not work, so i am suspecting it is a kernal rookit. These infections have tried to randomly install advanced anti-virus pro on my laptop this morning and running malwarebytes has cleaned it up and nothing had happened since then except detections. So I guess they are under control but I just can't get rid of it. I just ran Combofix half an hour ago and obtained a log, please let me know if you would like to see it. Combofix also quarantined some files which I did not realize was infected, but it did not solve the problem. I appreciate any responds and thankful to all the helps.

Regards,

Jeff

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

==>PLEASE DO NOT NOW POST LOGS<== unless a log is specifically requested.

Sorry it took so long for a response
First try DR Web


Please download Dr.Web CureIt, the free version & save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
---------------------------------

Then we need to scan for rootkits:


We Need to check for Rootkits with RootRepeal
  • Download RootRepeal from the following location and save it to your desktop.
  • Extract RootRepeal.exe from the archive (If you did not use the "Direct Download" mirror).
  • Open Posted Image on your desktop.
  • Click the Posted Image tab.
  • Click the Posted Image button.
  • Check all seven boxes: Posted Image
  • Push Ok
  • Check the box for your main system drive (Usually C:), and press Ok.
  • Allow RootRepeal to run a scan of your system. This may take some time.
  • Once the scan completes, push the Posted Image button. Save the log to your desktop, using a distinctive name, such as RootRepeal.txt. Include this report in your next reply, please.
