How to remove the "IAT" from the laptop.
« on: November 25, 2015, 03:13:48 pm »
Hello all,
when I checked the laptop so RogueKiller (Local 64bit) he found "PUP" and rootkit "IAT" who can not be removed. According of paint is it serious problem. After clicking on the "Delete" button and a reset laptop "PUP" erased, but remained rootkit "IAT".
Is it possible to remove the rootkit ? Please help!!!
I apologize for mistakes in English. I am not English, but I live in England.
Add part of the results of the control program RogueKiller.

Hi willH,

Welcome to Adlice.com Forum.
We are going to investigate those hooks.

Please follow the following process.
  • Download Process Explorer and save it to your desktop.
  • Click on the setup file (procexp.exe) and select Run as Administrator to start the tool.
  • When Roguekiller hang, locate the process named explorer.exe, right click select Create Dump > Create Full Dump...
  • Save the dump on your desktop and compress it.
  • Go to Adlice Software upload form, select the dumps as files to be uploaded and copy/paste a link to this thread in the "Comment" section.
Regards.

I do not understand this part:
When Roguekiller hang, locate the process named explorer.exe, right click select Create Dump > Create Full Dump...

I have also enable control involving RogueKiller or what should I do?

Hey :)
I'm in charge of looking at the dump.

Could you get the JSON report please? It contains much more information.
You'll find it in %programdata%/RogueKiller/Logs

Thanks.

I have not installed RogueKiller. I use a portable RogueKiller.
On cleaning I use ADWcleaner and this me shows no rootkit.
 Send you in an attachment RKreport from last cleaning

Thanks for the log.
Adwcleaner doesn't scan for rootkits.

EDIT: the hook doesn't show any malicious activity.
We will whitelist it.

EDIT2: The signature was already in the database under the name "Avast", so it's very probable it is (since I can see the avast module loaded).
I've changed it a little bit to include your hooks as well.

Hi willH,

The hooks are created by Avast and are perfectly legit.
We slightly modified RogueKiller so, starting its next release, it won't show them anymore.

You don't have to do anything. Thanks for your patience.

Regards.
