Badly infected machine, semi-cleaned, still having troubles.


Recommended Posts

I've been having a lot of trouble with my laptop recently, in particular I have been seeing an entry of explorer.exe in Task Manager that uses more than 2gig of ram on a 4gig machine (see image posted at http://imagebin.ca/v/1hvsujNzvIQz ).

 

After searching for info (an old friend always said "Google is your friend when you have questions"), I came across the Bleeping Computer website and ran the rkill app, which reported no findings.  However, when I installed and ran MBAM, what started as a list of 52 items exploded into 847 by the time the heuristic scan completed.

 

I have attached the xml version of the scan log since the log viewer function would not allow me to export the report as a normal text file. 

mbam-log-2014-11-24 (23-08-40).xml

 

Since the completion of that major scan, I am getting pop-up notices regarding several ip addresses attempting to be contacted by explorer.exe (5.149.250.194, 193.169.244.219, and 195.42.102.24).

After reading some other posts from this forum, I have already run scans with TDSSKiller:

TDSSKiller.3.0.0.41_24.11.2014_23.55.34_log.txt (run without loaded modules option)

TDSSKiller.3.0.0.41_25.11.2014_00.05.08_log.txt (run with loaded modules option)

 

And also with FRST64:

FRST.txt

Addition.txt

 

Any assistance you can provide would be much appreciated.

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll be working with you.
 
     
    
Before we start please read and note the following:

  • Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
  • Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
  • Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
  • Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
  • Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
  • Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
  • Note that we may live in totally different time zones, what may cause some delays between answers.
  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

:excl: I can't foresee everything, so if anything unexpected happens, please stop and inform me!
:excl: There are no silly questions. Never be afraid to ask if in doubt!

Here is the log.

 

Fixlog.txt

 

As I was posting this reply, my screen went black several times, and task manager again shows explorer.exe at 2.7 gig of ram in use.

 

Additionally, between the time I posted the logs from the re-run of FRST (around 12:15am my time) and the time I woke up this morning (around 9:30am my time), my internet explorer history list had several hundred entries for sites I did not visit myself...

Unfortunately, the laptop I am using did not come with a master restore disk, instead the manufacturer used a restore partition method (the drive is sectioned as 3 partitions, the main boot, one for the restore data, and one with "tools"). I am worried that the restore patition may be infected as well.

One thing I noticed right after posting those logs was that turning off the network connection to the router (and therefore all internet access), the process of explorer.exe that was so bloated actually reduces down to almost no activity or memory usage.

Ok, I just got home from work. I am using my phone to enter this reply while my laptop is temporarily network nullified. Based on my minor discovery right before i left for work (lack of internet connection puts the "beast" affecting my machine to sleep), I am rerunning the FRST test then the combofix test with all network adapters in disabled mode, keeping the computer internet free (and hopefully unhindered) for the duration of the testings.

Here is the protection log.

 

mbam_protection_log_20141127.txt

 

Oddly enough, the hijack, whatever it is, seems to be directly linked to the wireless network driver.  Everytime I disable the driver, the problem disappears.  Everytime I enable the driver, even if I don't have the wireless connected to the router yet, the hijack goes crazy trying to connect to sites.

I do not get involved in piracy. I use the peerblock program solely to block unwanted advertisement and suspected malware sites from being accessed during browsing. My children have used this machine in the past and it has been helpful in keeping them from seeing or clicking on sites not appropriate for their ages.

The only time i use torrents is when i am downloading a new linux dvd image, as it is faster than waiting for a download from a web page.
