Broken digital signature

[Vendetta]

Hey I have been clearing my PC of viruses, anyway I couldn't remove 3 and the error message I got was
"";"The file is signed with a broken digital signature, issued by: Valve Corporation., D:\Program Files (x86)\40K Space marine\Warhammer 40,000 Space Marine\spacemarine.exe";"Notification"

So I take it those are just false positives that it was smart enough not to delete?
