Hitman absolution virus alert Win32/Heur false positiv?? game crashes

[def_con]

hi after the newest update for hitman i have a big problem. my avg detects a Win32/Heur virus in the HMA.exe of hitman absolution.

because i get the data from original steam side i thought this is a false positiv and ignored it. but hitman does not start anymore.

there comes the popup which says:

"game not available: unspecified error"
or
"game not available: data corrupted"

has anyone the same problem or can help me?

Right click on the game chose properties and then look for verify files and let it do its thing.
