AntiRansomware - Strange Behaviour

[Massimiliano22]

Hi everybody,

I've installed Malwarebytes Anti-ransomware (BETA 0.9.15.416) on a Windows 7 virtual machine, downloaded some photos and pdf and then launched an attachment infected with Crypt0L0cker.

On the first execution,  all the photos in the test folder on desktop has been encrypted. Then Malwarebytes Anti-ransomware unexpectedly quit but the process of encrypting files stopped. The other files (pdf and txt) in download and other folsers, remained untouched. Reboot

On the second execution, the photos in the test folder were untouched (as the other documents) but in Quarantine only the cryptolocker files and registry keys from the first run are shown. reboot

On third execution, the photos in the test folder were untouched (as the other documents) but in Quarantine only the cryptolocker files and registry keys from the first run are shown. reboot

Thank you and best regards,

Massimiliano
