wer installiert denn solchen swiss-dreck überhaubt??
FYI: Having long had a paid premium copy of MalwareBytes, today my WIN7 system crashed, either at the end of a backup or in response to installation of MBAMswissarmyknife. Logs show 07:10:33 A service was installed in the system. C:\Windows\system32\drivers\MBAMSwissArmy.sys 07:11:43 Windows Backup completed successfully. Error 08:16:49 EventLog The previous system shutdown at 07:13:15 on ‎19/‎10/‎2016 was unexpected. However, while the file was installed in the right place, the filesize is 188KB. Neither an up-to-date and full scan using Symantec nor Malwarebytes itself detected anything wrong.
