Possible infection - trojan.filefill detected


Recommended Posts

My laptop was acting strange this morning-kept hanging and mouse slow to respond.  I ran a Malwarebytes scan and Trojan.filefill was detected and quarantined.  I deleted it also, but my computer is still quite slow.  I ran Farbar Recovery tool and logs are attached.  I also attached the Malwarebytes scan log.  I am running Windows 8.1.  Thank you in advance for your assistance.

Hello,

    

 

They call me TwinHeadedEagle around here, and I'll try to help your with your issue.

 

     

    

Before we start please read and note the following:

  • We're primarily oriented on malware removal here, so you must know that some issues just cannot be solved and you must be prepared for this. Some tools we use here will remove your browser search history, so backup your important links and all the files whose loss is unacceptable.
  • 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. Keep in mind that private life gets in the way too. Note that we may live in totally different time zones, what may cause some delays between answers.
  • 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.
  • I volunteer to help you, so please, do not ask for help for your company/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 not covered in my instructions happens, please stop and inform me!

:excl: There are no silly questions. Never be afraid to ask if in doubt!

The same applies to any use of P2P software: uTorrent, BitTorrent, Vuze, Kazaa, Ares... We don't provide any help for P2P, except for their removal. All P2P software has to be uninstalled or at least fully disabled before proceeding!

 

Failure to follow these guidelines will result with closing your topic and withdrawning any assistance.

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 :)

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.gifCCleaner - 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.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.
  • The program will run for a few seconds and display a notepad report. You do not need to attach it.
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.

My help is free for everybody.
