Hello,
Yesterday my free avast edition automatically updated from 5 version to new 6. My PC has OS windows 7. Once time installed new version, it was impossible to use internet. Pratically every adress I tryed to open, a message from Avast appeared to me saying that "site was potentially dangerous" or found a virus/malware and it was blocked. The same web adress (youtube, Facebook, libero.it) I opened without any problem with previous 5 version.
Someone could help to me ? Thanks a lot.
