Title: Rootkit warning, nothing detected?
Post by: irrelevant on October 19, 2011, 06:55:12 PM
Hi all.

I have a full scan scheduled for 2am daily.  Three times over the last month, it's reported multiple instances of "Threat: Rootkit hidden process" with a result of "Error: access is denied(5)", alternating between two different PIDs.

Doing a manual scan picks up nothing.  Running an f-secure boot-cd brought up no infections.  MBAM showed no infections.

Should I be worried, or is this a false positive?

Thanks

rob

Quick scan said nothing found. Full scan didn't find anything relevant, just a couple of files I knew were there.

It seems like rootkits and malware keeps getting more advanced I had one recently that couldn't be detected by avast malwarebytes or any other program.Ragnarok (http://www.existencero.com/?v=ragnarokprivateserver)It killed safe mode and infected my bios forcing my PC to keep resetting I formated the hard drive by hooking it to USB and had to reset the CMOS and reload the bios it was a CNA Training (http://www.cnatrainingdotcom.com) friggen nightmare.

The log appears clean - as the detections are referencing PID, I assume you are using a memory scan.  Which leads me to suspect that you are detecting signatures loaded into memory by an antimalware programme

Are you experiencing any unusual symptoms ?

I'm getting the "Threat: Rootkit hidden process" message too...and I never use Memory Scans.

Thanks for the help!  It's an avast full system scan that's picking it up, so I presume it's doing a memory scan.  I've also got Zonealarm installed, so maybe it's picking that up.  I'm not experiencing anything particularly unusual..  Hope it's just the AV being over-cautious then..

1. It's an avast full system scan that's picking it up, so I presume it's doing a memory scan. 
2. I've also got Zonealarm installed, so maybe it's picking that up. 
3. Hope it's just the AV being over-cautious then..

1. That's right.
2. I think so.
3. Yes, nothing to worry about. :)

Greetings!

I found this thread via a search after my avast complete scan caught several memory loaded spyeye, downloader, dialer, et al. in it's web. The fine insight provided for this other gentleman's query has me believing that's what happened with mine.

A quick question:

I run Avast Pro, Malwarebytes pro and win defender simultaneously. Is it OK in anyone's opinion? Should one be disconnected?

Also, if one cannot install Win7 SP1 would that be indicative of hanky panky?

Thanx,

griff
