@ Asyn,

@ ArthurG,

  1. Please disable the Avast Behavior Shield and run a Quick Scan, then a Boot-time scan.

  2. After this, please run an MBAM (Malwarebytes) scan free http://www.malwarebytes.org/. Make sure you update the MBAM definitions prior to scanning. Click the “remove selected” button to quarantine anything found. You will find the infection details under the Quarantine tab. Copy & Paste the entire report in your next reply (the log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM). I just want to be sure we are not missing any malware as a source of your problems.

@ Tourach,

I realize you have disabled the Behavior Shield to temporarily resolve your problems. But to fix it, you are advised to submit a mini-dump. Have you considered doing this as suggested in my previous post? Thank you.
