Just follow the guide and attach (Do not copy/paste) logs for AdwCleaner, malwarebytes’, OTL, and aswMBR.exe

You can attach the logs after you have finnished all the analysis. Just remember where you saved the logs.

Hi sjon12,

I notice you have

  • AVG
  • Avast
  • Symantec Endpoint Protection (Norton)

You may want to remove two of these. Running 2 or more antivirus software can cause soo many strange problems with your system. (Slowness and false positive)

You also have a Zero access variant on your system…

A malware remover may take some time to reply , so please be patient :slight_smile:

Download and Install Combofix

Download ComboFix from one of the following locations:

Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

  • IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

[*]Double click on ComboFix.exe & follow the prompts.
[*]Accept the disclaimer and allow to update if it asks

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now
