Possible virus infecting a CD game

Hello, I would like to know if it is possible for a maleware, virus, or trojan to infect a file on a video game disc? I have a game called Warcraft III and recently out of nowhere my AVG detected a trojan on the warcraft III.exe file and after doing full AVG and maleware byte scans and reinstalling the game the same problem persists. In question i tried installing the game on a different brand new computer and the AVG anti virus detected the same exact thing. I am not able to play my WCIII game on either of my computers. Any help with this problem would be very much appreciated.

 

If this helps any the AVG resident shield detection reveals Trojan Horse Generic 16.LYU and .LYL on file C:\program files\Warcraft III\Warcraft III.exe and a link on C:\system volume information\ which was found when i did a scan on maleware bytes anti maleware scan. Im not sure wether its internet related, pc related, or disc related.

 

If this helps any the infection that is noted on the file c:\program files\warcraft III\Warcraft III.exe is identified as a Trojan Horse Generic 16.LYU and .LYL. I need to know if this is a internet related, disc related, or computer related problem.

 

If it helps any the virus caught by AVG on the file c:\Program Files\Warcraft III\Warcraft III.exe has been identified as a Trojan Horse Generic 16.LYU and LYL. Any assistance on this would be greatly appreciated.

 

Thank you for your time in answering this post, and I do apologize for multiple posts i made. Luckily my AVG, came out with a new update which after scanning the problem has been fixed. If any other problems persist I will make a new post, untill then you guys can close this topic off. Thankyou for your time, take care.
