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 for the repair.

I definitely see some changes after applying zoek. There is no more multiple conhost,dllhost,taskhost and presentationhost. The internet speed turned back as usual as before being infected by malware.Maybe I need to see how it goes later but I believe it worked out well.
Now I should avoid using Malwared software like Utorrent :(

I was thinking to format and re-install Windows but now I don't have to do it anymore.
Let me know if there are further instructions not to put myself in the same problems.

Thank you so much and God Bless you!! You are the BEST, TwinHeadedEagle.

Since there are no more problems, we can declare this PC clean
thumbs_up_smiley.gif


Now, we can proceed with post-cleanup procedures. Let's remove my tools and create a new, non infected restore point concurrently deleting old ones.


Step 1. - Creation of system restore point and tools removal.


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). I don't need it for review.
Tool deletes old system restore points and creates a fresh system restore point after cleaning.


Step 2. - Tips and tricks to keep your computer clean, safe and in a good shape.


Security tips - highly recommended reading:

Maintenance tips:

Additional software that I personally use and install on all my clients devices:

  • Malwarebytes' Anti-Malware (paid version highly recommended) - to scan your system from time to time in search for malware.
  • Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
  • McShield - to prevent infections spread by removable media.
  • Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
  • Adblock - to surf the web without annoying ads!
  • Qualys BrowserCheck - cloud service that scans your browsers and plugins to see if they’re all up-to-date.


My help is free for everybody.
