Hello Steven,
Thanks for your reply.
The Cpl file is not related to android, but to the windows control panel.
Its not seems to be a false positive to me, because I receive many files like this by email (pretending to be a bill in my name), and usually avast always detect them as win32:malware-gen .
However this specific file is not being detected. So I was trying to understand why is it happening, specially when other antiviruses started to detect it (In the begin only 12 detected, now 29 are detecting).
Thanks for your time,
Tonanet
