When the infected file is executed for the first time, the virus will install itself in memory. Virus reserves 768 bytes for itself at the top of the free memory. Virus hooks INT 21h and INT 8h (system timer).
Virus will infect all executed files which are between 3 and 61441 bytes long. Virus checks whether the file contains string 'Dr' at the end of the file and determines this way if the file is already infected or not. The string is a part of text the virus contains: 'UnGame(C)Dr'.
Every 4096 timer ticks, virus checks if the video mode is 4, 13, or 19 the timer handler selects 1 of 8 routines to run - depending on timer count. These routines include warm reboot, some video and musical effects and a displayed message 'Come On, no.51, You Time is Up.'.
This virus has nothing to do with the Ungame product from DVD Software.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
