That is right after I did a scan with Malwarebytes’ and I did a full scan with Avast! and it found nothing! So should I delete the things Malwarebytes’ found?

yes

NO, not directly, not yet.

First add these files to the avast chest (see #### below):
c:\WINDOWS\system32\antiwpa.dll
c:\documents and settings\Cameron\local settings\application data\Install.exe

They remain in the original location, so after adding them to the chest, you should run MBAM again and remove those two files and the other registry entries.

This way avast gets a sample to analyse and help improve overall detections.

Send the sample/s to avast as a Undetected Malware:
Open the chest and right click in the Chest and select Add, navigate to where you have the sample and add it to the chest (see image). Once in the chest, right click on the file and select ‘Submit to virus lab…’ complete the form and submit, the file will be uploaded during the next update.
