Title: Root kit, aswMBR.exe Bsod
Post by: Bogartbc on August 25, 2012, 05:35:44 PM
Found a root kit yesterday after Cold Booting.  Deleted it with Avast then ran the prompted scan.  This came up clean.  I ran a full scan over night that came up clean.  I checked my auto starts finding a setwallpaper Unknown c:\programdata\setwallpaper.cmd.  I couldn't find this file with folder options set to show hidden, os folders, etc.  I couldn't find anything on MS about it.  I ran the 3 scans in on the Guide threat.  MBAM and OTL came up clean.  aswMBR.exe Bsod right after completing, I couldn't save that log.  I ran a second scan which I think is clean.

Given the Bsod I wanted to check if this was due to a Virus or software error.

aswMBR.exe logs.  Did you need the MBR.dat?

I also have the Bsod dump file if you need it.

Unfortunately I have no idea.  Avast popped up saying it found one with no real information displayed.  Delete was auto selected so I continued.  The boot-time scan prompt opened, I accepted and it restarted the system.  I can't find anything in the logs about it, most are dated after the long scan before windows boots and for the scan I ran overnight.  Sorry I didn't think to write what I saw down.

Are you experiencing any problems at all ?

Everything seems fine except I had to disable Web shield for IExplorer or Chrome to connect no matter what I set my firewall to do.  Steam, Xfire and Ventrilo worked fine with Web shield up.  Im just curious due to the aswMBR.exe Bsod and c:\programdata\setwallpaper.cmd which I can not find in Admin mode with folder options showing everything.

Have you allowed webshield through the firewall ?

The scan web (http) traffic was blocking the connect requests, I had to turn it off.  One would open for Avastsvc.exe at boot I would accept then my normal startups that make requests.  Chrome/IE would make one request I would accept but nothing loaded or made another request.  The Web shield doesnt really seem to be scanning anything though.

Im using comodo firewall,  I read on the forum that I should leave Web shield off due to a conflict between these two programs.

The webshield conflict with Comodo is on the Comodo side, and they want you to reduce protection by disabling Avast...  Personally I would change firewall

Do you have any suggestions for a Firewall that works well with Avast?  I've been using Comodo for some long Im not up to date these days.

Outpost is quite good I hear http://www.filehippo.com/download_outpost_firewall/

That seems pretty out of date, 2009.  Are the developers keeping it up to date via an update section similar to Avast?

No that date refers to when the first programme was added to fileHippo  ;D

Im am trying a few workarounds I have found on Comodo's forums to see if anything works.  I have on including the Web shield issue I posted about earlier.  If you have any information on these workarounds please let me know.  Both products I have been happy with the level of control so I'm hesitant to switch either program.


Are the logs I posted clean to you? 

Also is this Bsod a cause of concern?  I do not have the program to read this dump file so I do not know what caused it besides assuming a conflict with the aswMBR scanner.

The BSOD is no cause for concern... It happens on some systems

I can see no sign of malware on the system
