Welcome 
 
I'll be helping you with your computer.
 
Please read this post completely before beginning. If there's anything that you do not understand, please don't hesitate to ask before proceeding.
 
Please take note of the guidelines for this fix:

• Please note that I am a volunteer. I do have a family, a career, and other endeavors that may prevent immediate responses that meet your schedule. Do note that the differences in time zones could present a problem as well. Your patience and understanding will be greatly appreciated.
• First of all, the procedures we are about to perform are specific to your problem and should only be used on this specific computer.
• Do not make any changes to your computer that include installing/uninstalling programs, deleting files, modifying the registry, nor running scanners or tools of any kind unless specifically requested by me.
• Please read ALL instructions carefully and perform the steps fully and in the order they are written.
• If things appear to be better, let me know. Just because the symptoms no longer exist as before, does not mean that you are clean.
• Continue to read and follow my instructions until I tell you that your machine is clean.
• If you have any questions at all, please do not hesitate to ask before performing the task that I ask of you, and please wait for my reply before you proceed.
• Scanning with programs and reading the logs do take a fair amount of time. Again, your patience will be necessary. 

Let's begin... 

Please do the following so that we may take a closer look at your system for any possible infections.

Please restart the computer and do the following.

WARNING: Do Not click the Repair option under Advanced unless requested by a Malwarebytes support agent or authorized helper

NOTE: The tools and the information obtained are safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

• In the User Account Control pop-up window, click Yes to continue the installation

How is the computer doing?

Fixlog.txt

Hello friend, the computer was normal, I only noticed the infection when using the internet bank which blocked access for security... I no longer accessed the bank waiting for your response that everything was ok with the computer. He seems stable.

[JSntgRvr]

I believe that whatever was affecting your computer has been neutralized. Make sure you change your passwords.

Use this application to remove tools used and their quarantined items:
 
Please download KpRm by Kernel-panik and save to your Desktop.

• Click on KpRm.exe to run the tool.

Vista/Windows 7/8/10 users right-click and select Run As Administrator.

• Put a check mark next to these items:

- Delete tools

- Create Restore Point

- Delete now

• Click the "Run" button.

• When the tool has finished, it will create and open a log report and  delete itself.

A few final recommendations:

• Recommend using a Password Manager for all websites, etc. that require a password. Never use the same password on more than one site.
• Make sure you're backing up your files
• Keep all software up to date - PatchMyPC -
• Keep your Operating System up to date and current at all times -
• Further tips to help protect your computer data and improve your privacy:
• Please consider installing the following Content Blockers for your Web browsers if you haven't done so already. This will help improve overall security

Malwarebytes Browser Guard
