Full Version: Hidden Object - rootkit
Kaspersky Lab Forum > English User Forum > Protection for Small and Medium Businesses
Vladabgd
Hi, I have all ready wrote to support, however I have a few questions. I have tried some mail subscription management softwares, which I removed from my PC. Some of them used "server" applications. So I ended up with rootkit - hidden object attached to my default internet exploring software (IE6.0 or Firefox). I dont see it in system32, or in active processes. F-secure AVG anti-rootkit softwares sees this problem, but not solving it. Need assistance ASAP. By the way, what are rootkits???? How dangerous they are?

hello
which kaspersky product and what version are you using?

rootkits are applications which can hide themselves and other components from the windows API (the are invisible to normal applications). his is commonly achieved through kernel hooks. rootkits themselves usually have no payloads so they aren't "dangerous", but they are often used to hide other malware.

and it doesn't see it?
there are a number of rootkit tools you can try.
What does f-secure blacklight see?
another tool you could try is gmer: http://www.gmer.net/gmer.zip
it's advanced, but should be able to detect the toughest rootkits.

v7 will include a technology which enables detection of really nasty rootkits.
Vladabgd
All these software sees that I have dangerous hidden object - rootkit in C:\Program Files\Internet Explorer\iexplorer.exe (If IE6.0 is default) or in C:\Program Files\Mozilla Firefox\Firefox.exe.
Lucian Bara
that looks like something similar to nyfose which uses IE/firefox for it's doing.
try posting a combofix log, maybe we will be able to locate it: http://download.bleepingcomputer.com/sUBs/ComboFix.exe

the log will be located in c:\combofix.txt

But seeing as this is a workstation computer, it might b better to do a format and start clean.
Vladabgd
Yeah, I agree, but there are important files on this PC, so I can not consider formating now! dry.gif . Oh, and thanks for quick replies.

exactly that's why you should back up the files and reformat, if it's bifose, then it's a remote access tool, so those files can be leaked out.
Vladabgd
Here is report. Notice hidden process! And see picture attached! This is a office PC.

Hope, this is it!

I think we got it, delete the folder: C:\WINDOWS\windows and reboot.
wait a few hours (3-4), update and perform a full scan in safe mode
