Today I received the professional key V5 (AVR) by e-mail.

After the program was downloaded, I try to install FCv5 AVR but,
Avast comes with a malware warning after completing the licebtie key
REGME.EXE contains a virus (malware)...
Then I can no longer enter a key, and I'm unable to activate the product...
I never had any problems with Previous and other versions of FC .
FCv5 AVR has become useless now!

What do I do now?
