Very good. How is your PC behaving now?

[REDACTED]

So far, there is no indication of the problem.

First, let me say a big Thank You! to you and the others that help us remove these nasty things. Your help and support are without question.

Second, I am now keeping my kids away from my computer.Other than that, can you give me some indication of how this got on my computer. I will assume it was from site they visited.

Best regards,

Kids were probably installing some software bundled with Adware, I see no other way

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.

• How to configure and use Automatic Updates in Windows
  
• How to update Java
  
• How to update Adobe Reader
  

Recommended additional software:

CCleaner - to clean unneeded temporary files.
Malwarebytes' Anti-Malware - 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!

Post-cleanup procedures:

Download DelFix by Xplode and save it to your desktop.

• Run the tool by right click on the 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.
