Hi. Well, my laptop was being scanned by AVG and it detected 15 IRP Hooks, but AVG won't remove them. It says object is whitelisted (critical file system that should not be removed. Is this harmful to my laptop? Thank you for your help in advance.

Hello,lets see if we can confirm these Rootkits.
EDIT" does your AVG log look like this one?


Please download Rootkit Unhooker from one of the following links and save it to your desktop.
Link 1 (.exe file)
Link 2 (zipped file)
Link 3 (.rar file)In order to use this tool if you downloaded from either of the second two links, you will need to extract the RKUnhookerLE.exe file using a program capable of extracing ZIP and RAR compressed files. If you don't have an extraction program, you can downlaod, install and use the free 7-zip utility.

  • Double-click on RKUnhookerLE.exe to start the program.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • Click the Report tab, then click Scan.
  • Check Drivers, Stealth, and uncheck the rest.
  • Click OK.
  • Wait until it's finished and then go to File > Save Report.
  • Save the report to your Desktop.
  • Copy and paste the contents of the report into your next reply.
-- Note: You may get this warning...just ignore it, click OK and continue: "Rootkit Unhooker has detected a parasite inside itself! It is recommended to remove parasite, okay?".

To check for and confirm the MBR (Master Boot Record) rootkit.

Please download mbr.exe and save it to the root directory, usually C:\ <- (Important!).
  • Go to Start > Run and type: cmd.exe
  • press Ok.
  • At the command prompt type: c:\mbr.exe >>"C:\mbr.log"
  • press Enter.
  • The process is automatic...a black DOS window will open and quickly disappear. This is normal.
  • A log file named mbr.log will be created and saved to the root of the system drive (usually C:\).
  • Copy and paste the results of the mbr.log in your next reply.
If you have a problem using the command prompt, you can just double-click on mbr.exe to run the tool.

Nothing detected :(

And I tried the mbr.exe link, I double clicked it and followed instructions, then there was a black window that popped up for a second then it was gone and nothing happened. Also wanted to mention that my computer is also running slow. At first when I turn on the computer it starts normal but then after a while it slows down a lot.

After minimizing windows I saw a mbr-Notepad that said this:

Stealth MBR rootkit/Mebroot/Sinowal/TDL4 detector 0.4.2 by Gmer, http://www.gmer.net
Windows 5.1.2600 Disk: FUJITSU_ rev.891F -> Harddisk0\DR0 -> \Device\Ide\IAAStorageDevice-0

device: opened successfully
user: MBR read successfully
kernel: MBR read successfully
user & kernel MBR OK

Hello, did you see mu edit is post 2?

EDIT" does your AVG log look like this one?

These are False positives and they say will be corrected in the next update.

After minimizing windows I saw a mbr-Notepad that said this:

Windows 5.1.2600 Disk: FUJITSU_ rev.891F -> Harddisk0\DR0 -> \Device\Ide\IAAStorageDevice-0

device: opened successfully
user: MBR read successfully
kernel: MBR read successfully
user & kernel MBR OK

That indicates your Master Boot Record (MBR) is not infected.

If it were infected, you would have seen something like this:

device: opened successfully
user: MBR read successfully
kernel: MBR read successfully
MBR rootkit code detected !
malicious code @ sector 0x94fe9bd size 0x1fd !
copy of MBR has been found in sector 62 !
MBR rootkit infection detected ! Use: "mbr.exe -f" to fix.

Not all hidden components detected by anti-rootkit (ARK) scanners and security tools are malicious. It is normal for a Firewall, some anti-virus and anti-malware software (ProcessGuard, Prevx), CD Emulators sandboxes, virtual machines and Host based Intrusion Prevention Systems (HIPS) to exhibit rootkit-like behavior or hook into the OS kernal/SSDT (System Service Descriptor Table) in order to protect your system. SSDT is a table that stores addresses of functions that are used by Windows. Whenever a function is called, Windows looks in this table to find the address for it. Both legitimate programs and rootkits can hook into and alter this table.

API Kernel hooks are not always bad since some system monitoring software and security tools use them as well. If no hooks are active on a system it means that all system services are handled by ntoskrnl.exe which is a base component of Windows operating systems and the process used in the boot-up cycle of a computer. ARK scanners do not differentiate between what is good and what is bad...they only report what is found. Therefore, even on a clean system some hidden essential components may be detected when performing a scan to check for the presence of rootkits. As such, you should not be alarmed if you see any hidden entries created by legitimate programs after performing a scan.

Yes, my AVG said the same thing. I still think there's something wrong with my laptop because when I start it up it is fine, but after a while it just suddenly gets really slow, like it'll take a couple of minutes to load a new tab.
