What OS/SP ?
What exact avast version ?
Do you have other security (related) software installed ? (or did you)

What is your operating system and firewall ?

What avast version are you using, avast free/pro/internet security/Premier ?
What is the build number, avast 2015.10.2.2215 being the latest.

Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?
