AVG is telling me that my atapi.sys file is infected, and that it cannot be removed because it is an essensial file.
The infection is listed as Trojan Horse Packed.Protector.C, and the "process name" is C:\WINDOWS\system32\svchost.exe.

I installed Avast anti-virus and it reported a different virus infecting atapi.sys along with other files also being infected.
12/13/2009 4:05:25 AM SYSTEM 1572 Sign of "Win32:Malware-gen" has been found in "C:\WINDOWS\TEMP\~TMDE.tmp" file.
12/13/2009 6:09:46 AM SYSTEM 1572 Sign of "Win32:Cutwail-AD [Trj]" has been found in "C:\WINDOWS\SYSTEM32\DRIVERS\atapi.sys" file.
12/13/2009 10:58:03 AM SYSTEM 1572 Sign of "Win32:Alureon-ET [Rtk]" has been found in "C:\WINDOWS\Temp\8.tmp" file.

The problem with atapi.sys is not going away even with a MalwareBytes scan. My ISP reported to me that my computer has been sending out a huge amount of emails and it seems my computer is infected.

PLEASE HELP!!!

In one of the posts before registering , I saw that new users were advised to run DDS and a rootkit analysis tool before posting. I couldn't find that post again after registering and none of the pin-ups in this sub-forum advised to do that. If that is needed please do let me know.

Please run :thumbsup: SAS

Also run

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)

I ran web cure it. It found out c:\windows\system32\atapi.sys and c:\windows\system32\cdrom.sys . I set it to move incurable. It went ahead and after the scan deleted it. After reboot I can no longer boot the system. I have the original windows xp cd service pack2 with me. I will try to install atapi.sys and cdrom.sys from that CD.
