Hi steviewilson,

Please post the log from the last Malwarebytes scan.

Well for some reason the log never saved! So I removed the highlighted files and malicious files, rebooted, did another scan and ZERO infections came up! I did a HJT scan and have included that log.

Think Im out the water now? Fingers crossed!

It's looking good, as a final check, please go to

Kaspersky website and perform an online antivirus scan.

  1. Read through the requirements and privacy statement and click on Accept button.
  2. It will start downloading and installing the scanner and virus definitions. You will be prompted to install an application from Kaspersky. Click Run.
  3. When the downloads have finished, click on Settings.
  4. Make sure these boxes are checked (ticked). If they are not, please tick them and click on the Save button:
    • Spyware, Adware, Dialers, and other potentially dangerous programs

[*]Click on My Computer under Scan.

[*]Once the scan is complete, it will display the results. Click on View Scan Report.

[*]You will see a list of infected items there. Click on Save Report As....

[*]Save this report to a convenient place. Change the Files of type to Text file (.txt) before clicking on the Save button.

[*]Please post this log in your next reply and also let me know how your computer is running now.
