I already followed the instructions of this post https://forum.avast.com/index.php?topic=53253.0, and send you the logs in the attachment. After using MBAM to clean the infected files, the alerts of avast are no longer appearing but I´m not sure my notebook is completely free of this malware.
Please go to START (Windows Orb) >> Control Panel >> Uninstall a Program or Programs and Features and remove the following (if listed):
PCSpeedUp
To do so, left clicking on the name once and then click Uninstall/Change at the bar above the list window.
Follow the prompts of the uninstaller BUT please read carefully any questions it asks before answering; some uninstallers will try and deceive you into keeping the software.
Let’s get our tools cleaned off and you on your way !!!
Clean up of Malware Removal Tools
Now that we are through using these tools, let’s clean them off your system so that should you ever need to have malware removed again (we hope not) fresh, updated copies will be downloaded.
[]Download Delfix from here to your desktop and double click it to start the program
[*]Ensure Remove disinfection tools is ticked Also tick:
[]Activate UAC
[]Create registry backup
[]Purge system restore
[*]Reset system settings
[*]Click Run
[*]The program will run for a few moments and then notepad will open with a log. Note: Please save this log first before rebooting your system (if asked to); DelFix does not save the log as it is trying to remove all traces of our work on your system. Please attach the log in your next reply.
You can delete any log files left on your desktop as these are no longer needed.
