Hi ds123,
As it's now being blocked again in Avast Free, we can rule out the paid components as the cause of the issue. The culprit is therefore likely to be one of the Core Shields, specifically Behavior Shield.
Can I ask you to upload the FM12 executable file to
VirusTotal, so that we can investigate this further? Once uploaded, please wait for the scan to finish, and then please post the URL for the VirusTotal page here after the scan has finished.
You can find the file in either the
C:\Program Files (x86)\Steam\SteamApps\common\Football Manager 2012 folder or the
C:\Program Files\Steam\SteamApps\common\Football Manager 2012\ folder depending on your system.
