My antivirus software has dedected vista7.dll as a trojen horse and deleted it. It says Backdoor.Graybird is a back door Trojan Horse that gives its creator unauthorized access to your computer. The existence of the file, Svch0st.exe, is an indication of a possible infection. Backdoor.Graybird is a Delphi application.
We haven’t created vista7.dll, so we can’t know for sure that it is not a trojan. With that said, vista7.dll is a “hack” in order to get C3 working in Windows Vista/7/8, as the game was originally only developed for WinXP.
Thank you Sir but i can not recover that dll file. Even i disable my antivirus and redownload the dll, something deletes that vista7.dll immediately. May be some windows services delete it? Does any one has any iadea to solve that problem?
