I have a problem with a computer that is connecting to foreign ip addresses with explorer.exe.

 

It started with a component that was installed from a website, then Norton blocked a web attack (web attack exploit toolkit website 5). Norton has continued to block attacks from websites and attempts to download trojans

 

Since then explorer.exe has been running very slow. We noticed multiple connections to foreign ip addresses in the resource monitor. I have created firewall rules to block explorer.exe from connecting to the ip addresses, but new connections continue to pop up.

 

We also noticed Internet Explorer was not connecting to some websites...resetting defaults and disabling add-ons fixed this.

 

I have run a few tools to try and remove the problem but nothing of significance has been found. Here are the tools previously run:

TDDSKiller

RougeKiller64

MalwareBytes AntiRootKit

MalwareBytes AntiMalware

ComboFix

 

I have attached the FRST.txt, Addition.txt, ComboFix log, and RougeKiller log.

 

Any help would be appreciated, thank you.

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!

  • When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please post it to your reply.

Hi,

 

I've been monitoring the pc for a few hours and there hasn't been any strange activity...explorer is running faster, no multiple connections to foreign ip addresses, and Norton isn't blocking attacks.

 

Looks like things are back to normal!  I'll keep monitoring the pc for the rest of the day.

Glad I could help. We will delete all used tools and I'll give you some tips to harden your security and learn how to protect yourself :)

icon_exclaim.gifMUST READ - general maintenance:

The Importance of Software Updating:


In order to stay protected it is very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.


Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.

Recommended additional software:

icon_arrow.gifTFC - to clean unneeded temporary files.
icon_arrow.gifMalwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gifMalwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gifMcShield - to prevent infections spread by removable media.
icon_arrow.gifUnchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gifFiheHippo.com Update Checker - to keep your programs up-to-date.
icon_arrow.gifAdblock - to surf the web without annoying ads!
 
 
 


Post-cleanup procedures:

 
 
Download DelFix by Xplode and save it to your desktop.

  • Run the tool by right click on the 51a5ce45263de-delfix.png icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run and wait until the tool completes his work.
  • All tools we used should be gone. Tool will create an report for you (C:\DelFix.txt)

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.
