Hello,



They call me TwinHeadedEagle around here, and I'll be working with you.



Before we start please read and note the following:
  • At the top of your post, please click on the "Watch thread" button and make sure to check Watch this thread...and receive email notifications. This will send an email to you as soon as I reply to your topic, allowing me to solve your problem faster.
  • Please do not install any new software during the cleaning process other than the tools I provide for you. This can hinder the cleaning process. Please do not perform System Restore or any other restore.
  • Instructions I give to you are very simple and made for complete beginner to follow. That's why you need to read through my instructions carefully and completely before executing them.
  • Please do not run any tools other than the ones I ask you to, when I ask you to. Some of these tools can be very dangerous if used improperly. Also, if you use a tool that I have not requested you use, it can cause false positives, thereby delaying the complete cleaning of your machine.
  • All tools we use here are completely clean and do not contain any malware. If your antivirus detects them as malicious, please disable your antivirus and then continue.
  • If during the process you run across anything that is not in my instructions, please stop and ask. If any tool is running too much time (few hours), please stop and inform me.
  • I visit forum several times at day, making sure to respond to everyone's topic as fast as possible. But bear in mind that I have private life like everyone and I cannot be here 24/7. So please be patient with me. Also, some infections require less, and some more time to be removed completely, so bear this in mind and be patient.
  • Please stay with me until the end of all steps and procedures and I declare your system clean. Just because there is a lack of symptoms does not indicate a clean machine. If you solved your problem yourself, set aside two minutes to let me know.
  • Please attach all report using
    fjqb1h.png
    button below. Doing this, you make it easier for me to analyze and fix your problem.

  • 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.

Thank you so much for working on my laptop's problem.
Here I upload the reports you asked me to. The program you asked me to run detected 6 malwares and I cleaned them all up. My laptop seems to work better, but I am waiting for your call.
I like your profile picture by the way.

Let's run one more scan. How is your PC now?


51a5bf3d99e8a-ComboFixlogo16.png
Scan with ComboFix

This is a very powerful tool that should be used only if advised by Malware Analyst.
Do not run ComboFix on your own!


Referring to this instruction, please download ComboFix by sUBs and save it to your desktop.
Temporary disable your AntiVirus and AntiSpyware protection - instructions here.

  • Right-click on
    51a5bf3d99e8a-ComboFixlogo16.png
    icon and select
    RunAsAdmin.jpg
    Run as Administrator to start the tool.
  • Accept the disclaimer and agree if prompted to install Recovery Console.
  • Do not take any actions while ComboFix goes through your System - it may cause it to stall!
  • This scan may take some time!
  • When finished - it will display a logfile (located also on your main drive, usually C:\ComboFix.txt).

Include that log in your next reply.

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 :)

MUST 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.gif
TFC - to clean unneeded temporary files.
icon_arrow.gif
Malwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gif
Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gif
McShield - to prevent infections spread by removable media.
icon_arrow.gif
Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gif
Adblock - 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.

I really appreciate your help. My laptop works great now, and here I upload the Delfix report. One thing is that I ran Delfix twice, because the first running didn't clean up some of the disinfection tools that I had placed in folders different than 'desktop'. So the second report deleted the first Delfix as well, but I think the first and second running have cleaned up everything successfully, except for one file, which was the Malwarebytes Anti-Rootkit.exe file, which I have deleted by my self right after.

Thank you again for your help and the very useful information!!!

Oops there seems to be one more problem, but if you want me to post a new thread for this, plz let me know. I replaced my old anti-virus program with microsoft essential, but it shuts down when I run a whole-scanning.

with Malware - during intial scan , when going through partitions, it list Partition 0,1,2,3

0 type is other (APROX SIZE 2040MB)
partion is active
NTFS BOOTABLE

1 type is primary (main size - LARGE)
partition is not active

other 2 are not active also - but non important. is everything alright with first two? is that how it works? I believe that 2gigs or w/e is windows on a partition

and other is the actual installed/programfiles etc

cpu 50percent
