Win32/PSW.Lineage.DN/ PWS-Lineage

Had a game called Air Conflicts installed on my PC (Vista Home

Premium) and it worked very happily, I got bored with the game and

removed it.

Have had some young relatives staying so decided to re-install it for

them. It installed fine but when I try to use it I get "ac.exe has

stopped working" followed by a message from Microsoft saying

"Virus alert: Microsoft detected the Win32/PSW.Lineage.DN/

PWS-Lineage virus on your computer

This problem was caused by Win32/PSW.Lineage.DN/ PWS-Lineage, a known

computer virus.

I am running NOD32 which indicates no problem and neither does

Malwarebytes.

The install was from the same disc as my first install.

Googled for an answer but only found other people with games getting

the same message.

Any solution greatly appreciated !!
